Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/
Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.
We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Perpay | Senior Full Stack/Backend Engineer + Engineering Manager | Onsite in Philadelphia, Full-Time
Perpay is building financial products backed by users' paycheck direct deposit. We believe everyone deserves a chance to improve their financial future, and we’re dedicated to building simple and inclusive financial products that help our members create healthy habits and achieve economic stability. We've really hit our stride in terms of growth the last 18 months, and that curve is still steepening.
We're looking for:
- A few Senior Full-stack or Backend Engineers across our 3 product engineering teams. We highly value product-mindset, experience building production web apps for real users, and ability to coach and support more junior engineers.
- A technically hands-on Engineering Manager. Ideally, you have at least a year or two of experience leading people and being accountable for a team's execution, roadmap, and performance. You would be the fourth "line manager" on our team, and so there's ample opportunity to grab org-wide initiatives that are interesting and impactful.
Our stack includes AWS, Postgres, Python/Django, React/Redux/Typescript, Datadog
Some other company notes / benefits: Open PTO policy, full health/dental/vision, strong total cash comp, remote weeks around major holidays + extra holiday on weekends like MDW and LDW, catered lunch 3 days/wk, 401k w/ solid match, cell phone plan, gym subsidy, and some student loan repayment match.

We're also heavily focused on making ethical scraping the default (robots.txt checks, rate limiting, any custom compliance rules).
But we can't do it alone. We are looking for people who share our passion for software craftsmanship, data, and AI. We are growing fast, have a “no-bullshit” policy, and try to minimize the distance between the code you write and the customers who use it. We iterate to greatness :)
If that sounds like you, please email me at (adrian at kadoa dot com) and mention HN in the subject line. Ideally you include an ETL or scraping project you've been working on in the past.

Phrasing is a bootstrapped company dedicated to building the most effective and efficient way to learn a language.
I’m a polyglot myself and have always struggled for a few main reasons:
1. Apps only ever focus on taking you from 0-1, never from 1-100.
2. If you have any experience in the language, it’s really hard to pick it up after a few years.
3. Language learning apps are always ugly, clunky, ugly, and just stressful to use. And ugly.
4. No apps support maintaining and learning multiple languages simultaneously
5. Apps only ever support the major languages, leaving minority languages in the dust
So, I set off to build my dream language learning application, and a quick 2 years and 10,000 hours later I’d built Phrasing.
It’s launched, it’s live, it has (happy) paying daily users, and I myself am using it to learn 18 languages. The product is ready to go, and the business is already growing organically.
I’m looking for someone cracked to come in in a co-founding capacity and eventually take over the backend (elixir) codebase from me.
No experience is required so long as you’re passionate, talented, and hungry.
If you’re interested, and located in Europe, send me an email at hn@phrasing.app.
Hunh. It feels weird to say "Language learning apps are always ugly, clunky" and "Apps only ever support the major languages, leaving minority languages in the dust" when those are a few things that Duolingo actually does fairly well. Don't get me wrong, Duolingo has a LOT of flaws and I'm excited to hear you're building an alternative to it, just the pitch feels like it's based on a time when Rosetta was the name to beat.
That’s a fair point. It was originally “Those that work are always…” but I lost that preface in some refactoring.
I think it’s quite obvious though why Duolingo doesnt disprove any of my points. There was and is still no pleasant, multilingual, effective language learning app on the market. For the most part, you can choose one of those (and no, I do not consider Duolingo “multilingual” in the sense most polyglots need :) )
I personally find it quite ugly and clunky. I feel like the interface is optimized for children, and the number of ads you have to tap through to get even a modicum of knowledge is quite clunky. The last time I used it I spent over 20 hours to partially learn almost 4 letters of the Arabic alphabet — I’d call that pretty clunky.
Objectively they have a good team, but I do not think it’s above crticism in either regard.
It doesn't look like any of the TTS solutions are sufficient. I'll be removing the language limitation sometime next year, once the interfaces are built out for custom audio and custom annotations.
If a good Dzongkha TTS comes out, then I'd be happy to integrate it natively!

Ditto | Public Safety Forward Engineer | Full-time | Remote (North America preferred)
Ditto is building an edge-first, peer2peer database and streaming APIs that solve challenging data synchronization problems. Our core is built on CRDTs and Rust.
If you know networking, ATAK, p2p, ROS2 or wireless MANETs please apply. I’m building out a team to apply the technology to life saving markets and need a hand.

About us: Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.
The problem we’re solving: Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.
We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.
Why it matters: This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.
The role: We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions

Compensation
-Salary + meaningful equity. Sponsorship available for exceptional candidates.

We also believe in compliance and security from day 0.
We're looking for someone with deep healthcare integration experience to hit the ground running. Ideally they're a pragmatic backend expert to help us scale as we continue to grow. Integrations can be a full time role, but at a startup it's necessary to wear many hats. So this individual should also feel comfortable as a generalist who can jump in at any part of the stack.

CLUTCH | Hardware/firmware Engineer, Product Designer, Head of Growth | Remote | Full-time

Fusionbox | Python + TypeScript Engineers | United States| Full-time | REMOTE (Legal to work in the US)
We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
I'd be curious what statemachine libs you're using. The open source side of python statemachines is pretty limited (though python-statemachine is rather nice and its repo owner is a pleasure to work with).
Something on the typescript side? I've seen that union types can be rather elegant for representing the structure of a statemachine.

We love working together with our customers - construction is truly a unique place where each project is its own micro universe.

Sitch App | Founding Product Manager | NYC-area HYBRID (2-3 days/week in NYC near Union Square) | Full-time
Sitch is a new type of concierge dating app. We're using AI + Humans to ask you questions, get to know you, then help you find love.
We're an AI powered concierge matchmaker for serious daters. Sitch is live in 5 cities and expanding nationally in 2026.
We're philosophically opposed to the dopamine-fueled mini-game doomswiping of 'traditional' dating apps which cynically monetizes desperation. We're monetizing intent!
* We're top-tier VC funded (a16z Speedrun, M13, early Snap angels)
* Looking for a PM who loves building for consumers, loves relationships, is a bit unusual, and is obsessed with building unique experiences only made possible with the new era of LLMs
* 2-3 days/week in person, in Manhattan near Union Square
Site is at https://joinsitch.com, and feel free to send me (Chad) and Dini (co-founder) a note at hi@unusual.inc
How are you dodging the cross-concerns of 'people who use the app more are more likely to dump money into it'? At present, customers who pay are more desperate than customers who don't, so income is directly tied to customers who can't find a partner.
probably a longer answer is warranted, but we keep it simple - everyone pays - which essentially eliminates ghosting and self-selects for people who are serious about a search for a partner.
Lantern | NYC only, hybrid 4 days a week in office | Senior Software Engineer (mid career - Staff)

Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)
In education, we have always traded off scale and quality. In a 30-student math class, half of kids are ready to accelerate while half are still working on their foundational skills, but teachers cannot be in 30 places at once, giving each student one-on-one support.
Until now. Imagine 30 teachers in every classroom—that's how Goblins feels. Students draw math on any device, and our AI figures out the "why" behind their confusion, giving instant feedback and building conceptual foundations. (Try it out here! https://app.goblinsapp.com/onboard)
Goblins launched to school districts in the spring of 2025. Since then we've built a waitlist of thousands of teachers and sold Goblins to districts across the US (we'll hit 100k+ paid students this year!). We are in the unique position of having a product that is both highly differentiated and demanded :)
Technical problems that we find interesting:
→ Building knowledge graphs that adapt to student performance in real-time, routing them to the optimal next problem they should solve to maximize learning and engagement.
→ Extending our handwriting recognition from digital canvas to real paper through Chromebook cameras (think real-time OCR on math equations through low-quality webcams with poor lighting)
→ Creating interactive mathematical lessons (think 3blue1brown, but conversational) that remediate student misconceptions.
You'll be joining founding team members Sawyer (CEO, former Head of Design at X1 [acquired by Robinhood] and math teacher) and Alp (CTO, ex-Stripe and Amazon), plus two other exceptional founding engineers.
We move fast, care deeply about craft, and obsess over delighting users. If you're interested, email alp@goblinsapp.com :)

We are hiring for:
- Fullstack engineer for our internal research management web application
On the data side: AWS, Cloudflare, Snowflake, Clickhouse, Dagster
Obviously, we are not the only ones trying to figure out how to use AI in investing but in a world where there are lots of people trying to build picks & shovels, this is an opportunity to be one of the goldminers at a greenfield, new firm. This role makes sense for people who are interested in finance/investing (although you do not necessarily have to have experience in the industry).
We're in full-time in office in NYC, so that's a requirement for FTE.
We work very hard, hours are long, and people are very dedicated to the mission. It is not for everyone, but for those interested in competing in financial markets, love startup atmosphere without near-term existential risk, and want to work with super smart colleagues (both technical and investors!), this could be a great fit.
I write about hedge fund data teams frequently here, if you are just interested in learning about the space: https://magis.substack.com/
Target salary 180-250K, depending on experience + Bonus/Carry (hedge fund equity equivalent)
Contact: I am at: ai (at) nx1 (dot) com (I'm Alex, ai are my initials... you are not being sent to an ai :] )
--
What we're looking for:
- 4-8 YoE in Typescript (we use Vue) + Python experience
- Ability to be in-office in NYC
- Bonus: SQL (ie. you know Window Functions), AWS (ie. you'd know how to configure an IAM role)

This may not be the “right” place to ask this, but I am a software engineer in the entertainment industry and it’s pretty bad right now. What is a pivot I can make? My skills are mostly C++ and Python.
If you want to get into AI topics: start learning about LLMs, embeddings, vector stores, datasets, fine-tuning, evals, and how to use CLI dev tools like Claude Code.
Andre Ng helped build a great free resource with courses: https://www.deeplearning.ai/ (some are sponsored but still free)
I think a quicker pivot (job wise) would likely be Python web development. They already know Python. Then layer on LLMs when doing that job (with more "runway")

Leadership Development – Strategic Partnership (Remote)
Are you an established consultant or a retired executive with a network you're not ready to stop using?
This isn't a job; it's a strategic partnership. We are Relationship Media, LLC, a leadership education company founded by a 20-year law enforcement veteran and former S.W.A.T. commander. We have a proven, "sticky" training program that solves the single biggest problem in organizations today: The Relationship Gap.
We’re not selling abstract theory. We sell a practical, example-driven blueprint for leadership (using our proprietary "Be Like Tony & Don't Be Like Chad" framework) that helps organizations in public service, manufacturing, and healthcare solve their $223 billion crisis of cultural disconnection.
We have the product. We're looking for partners who have the relationships.
The Opportunity: Two Ways to Earn
We are recruiting a small team of commission-based partners to bring this vital training to their networks.
1. The Certified Partner (White-Label):
This is for independent consultants, coaches, and trainers. We will white-label our entire online course with your brand, logo, and welcome video. It becomes your product. You sell it to your clients and keep a significant portion of the revenue. Stop trading your time for money and add a scalable, recurring income stream to your practice.
2. The Affiliate Partner (Referral-Based):
This is for retired executives and well-connected professionals. You make high-level introductions to your network (City Managers, Police/Fire Chiefs, Plant Managers, HR VPs). When we close a deal for in-person or online training, you earn a generous referral commission. You leverage your credibility; we do the rest.
Who We Are Looking For:
• Profile 1: The Independent Consultant. You are an HR, OD, or leadership consultant, etc., looking for a proven, high-quality curriculum to sell to your existing clients.
• Profile 2: The "Encore Career" Executive. You are a retired/semi-retired leader (e.g., City Manager, Police/Fire Chief, HR Director, Operations VP, etc.) who wants to leverage your network for a flexible, lucrative, and meaningful opportunity.
This is a 100% commission-based partnership for established professionals who understand that their relationships are their most valuable asset.
If you are a high-level connector ready to monetize your network by solving a real-world problem, we want to talk to you.
BuildBetter | Senior Engineer (Backend, Full-stack) | Full-Time | Remote (US) | 170-200k base + equity | Visa Sponsorship not provided
BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, and Posthog, automate the operations work that lets them provide their customers with world-class product experiences.
We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.
Joining us will mean solving hard problems at the frontier of AI adoption, including:
- maintaining performance at scale
- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.
- building agent and workflow systems that automate real work for customers
- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly
- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems
- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work
- health insurance

Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?
We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen
Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.
krea.ai | Distributed Systems Eng. & Data Engineers | San Francisco (on-site & remote), CA
I'm the cofounder & CTO of Krea (https://www.krea.ai). We are a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and professional creatives. Small team (~24); millions of active users; and raised over $83M from top Silicon Valley investment firms.
We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.
The job:
- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.
- Learn ML engineering from world-class researchers on a small tight-knit team. You’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions.
- Play with huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.
Tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational DBs, PyArrow, etc.)
You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for experience with dist. systems, k8s, and existing ML or data experience (but not required!). Cool side projects are a green flag.
Pareto.AI | Multiple Roles | INTL REMOTE, US REMOTE OR HYBRID (SF) | https://pareto.ai
Pareto.AI is in the premium data annotation space, focused on ethical, high-quality data annotation. We work with almost all of the frontier labs. We are a fully distributed, remote-first company with engineering teams spread around the world. Some of us work hybrid from our office in SF. There is essentially no restriction on where you're located as long as you're not from a sanctioned country and are willing to adjust to either a US or EMEA timezone.
We have a few full-time, fully-remote roles available. For those two below, we've recently restructured how we do engineering at Pareto and are looking to be very talent dense. I've hired successfully from HN multiple times in the past, so if you have expertise in those respective tech stacks I'd love to chat:
We're also looking to hire some shorter term contractors. We have a couple of projects around refactoring and migrating to a new design system, as well as some shorter term projects around compliance, so if you're only available for a short time we'd likely have room for you too:
Backend code-writing roles require a really strong command of Python. Equally for the frontend roles you really need to understand your TypeScript and React. You're expected to have a lot of responsibility.
You can reach me directly at steven@[domain] if you have any questions that aren't covered by this post or the job listings, but any applications would need to go directly through the link above. After you have applied, feel free to drop me a one-liner email with the subject "Via HN: Applied" letting me know so I can make sure you don't get caught up in the screening flow.

We build the user-facing products for inbound email security and have many interesting challenges working at massive scale. Please see the following links for more details on the open positions and our general careers page link for all open positions across the company. We are hiring for engineering in other divisions as well!

Hi Pallavi, thanks for your interest in this position. We only allow referrals for people we've worked with before but I will ensure your resume gets reviewed by the hiring manager.
We’re a tech-enabled E&S MGA on a mission to modernize Specialty insurance. The industry is burdened with legacy technology and inefficient processes, preventing innovation at scale. We are changing that. Our goal is to become the best-in-class full-stack insurance and re/insurer, leveraging AI and data-driven insights to revolutionize underwriting, pricing, and risk selection. We believe in talent density—fewer, better people working together as one. We win as a team.
Requirements (vary by role):
Strong ownership and bias for action; clarity in written communication; hands-on delivery in lean teams; comfort with ambiguity and high standards. Deep experience with one or more areas above (shipping production systems, data pipelines, LLM apps, or secure/AWS infra).
Benefits:
Competitive comp + equity, medical/dental/vision, PTO, remote-first with periodic team onsites.
Apply: email hiring@ledgebrook.com with subject “HN: — ”. Please include a brief note on why Ledgebrook, a recent project you’re proud of, and your LinkedIn/GitHub. We’re actively hiring and will respond to applicants.
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS product or AI wrapper, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.
Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool new AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

Critical Open Roles - Engineering, AI/ML, Product, Design:
We recently raised our Series B from notable venture capital firms, including Khosla Ventures and PayPal Ventures. We have strong unit economics and are on track to (more than) double our revenue growth this year. These are super positive signals for our company, emphasizing product market fit and stability as an early stage startup that's well positioned for continued growth.
Trinsic | Software Engineer | REMOTE (North America) | Full‑time
We’re building the first Identity Acceptance Network—the “Visa for ID.” Humanity is editing genes, starting space tourism and working on artificial intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards . We’re bringing identity into this new age, where trust is essential and becoming more so every day with AI. We enable accepting digital IDs that users already have (mDLs, BankIDs, reusable IDs) and verify users ~10x faster across 40+ networks covering 500M+ people.
Role
- Software Engineer (#5 on the team; ~20% of eng capacity). High ownership, product-minded, backend and systems leaning.
- You’ll ship fast, prune scope, and help shape our engineering culture.
- You’ve thrived in early-stage environments, can tackle fires independently, and care as much about product as code.
- Strong backend experience; generalist who enjoys moving up/down the stack.
- You care deeply about user privacy and data security.
- Remote‑first in North America; strong async work habits; <5 hrs/week of recurring meetings; frequent pairing/huddles.
- We’re keen but responsible adopters of AI tooling to hit our high bar of excellence.
Comp & benefits
- Salary set by a transparent formula (we target ~60th percentile cash for our stage) + meaningful equity, usually 90th+ percentile for a startup of our stage.
- Premium US healthcare (75% of premiums covered for you & dependents), at least 15 days PTO, $900/yr fitness stipend, $350/mo coworking or $200/mo home office, first week is “Think Week” to help you transition into your new role, paid family leave, top‑tier laptop, twice‑yearly in‑person offsites.
Since we do location based pay (based on benchmarks) it's tough to give a range as it'd be a huge range (North America has a significant variety of pay scales), and the various levels themselves in just the US have big ranges as well.
We'll address this in our first orientation call with a candidate to make sure we're in the same ball park of ranges.
But point taken, we'll look into if we can make some range indications available. For now, if you lookup compensation ranges for companies in our peer group and your geography it should match, but very happy to discuss your specific during a call.
it's philosophical only in your head. In real world if you are geared towards exploiting people you will always find good enough explanation to make you feel better. In this case that reason is location.
MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.
We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position.
For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
We're looking for remote junior engineers that have 0-3 years of professional experience in software, and 5+ years of curiosity exploring computers, programming, and technical hobby projects. This is an open-ended entry role with mentorship and diverse opportunities to work on all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more. To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.
Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule.
We're hiring generalist software engineers to work on web applications, data mining, machine learning/data science, data transformation/ETL, data modeling, database scaling, infrastructure, devops, and more. We'll cater the role to whatever subset of these areas match your interests.
Beneficial experience includes PostgreSQL, Python, Rust, Linux, TypeScript, Nix, frontend/backend web development, and data mining.
I’m Kiran, Chief of Staff (CoS) at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
Sounds familiar. This is the company that wants to pay ~$2k a month and is looking for engineers in the third-world. They will also deny you if you are in the US and looking to put something recent on your resume and don't care about salary.
Babylon Labs | https://babylonlabs.io/ | is building native use cases for Bitcoin, unlocking its broader economic potential through trustless Bitcoin staking with over $6B in native BTC TVL and the new trustless Bitcoin vault that enables BTC to participate in DeFi across any chain.
I'm getting it from the fact that you aren't showing people a job posting. Nor are you asking about their experience. Your application process is to send you ideas for growth. That is why it sounds like free consulting.
I know the kind of person you are looking for. I am that type of person. And I'm telling you there is no way I'd download an app and send my ideas in as part of a job application. I'd gladly do so as a small paid gig during the application process, when we have talked and it feels like my experience matches your needs. But not as the initial contact, no way.
Novig | Multiple Roles | New York | Onsite | Full-time
Novig is rebuilding sports betting from first principles as a prediction market exchange. Legacy sportsbooks are extractive middlemen with misaligned incentives, dark patterns, and predatory mechanics. We're creating the alternative: a transparent exchange where users trade against each other at fair odds.
We're building core infrastructure around order routing, risk management, data pipelines, low-latency networking, and market integrity at scale. We write Rust extensively. We believe correctness, performance, and expressive code are necessities rather than luxuries. Ideal candidates care deeply about infrastructure, security, and performance. It certainly won't hurt to also care about prediction markets, traditional markets, or well-designed distributed systems.
About me:
Hi, I’m Giorgi — a Full-Stack Web Developer with around four years of experience in frontend development and about a year in backend and AI-related work. I’ve collaborated in various settings — from freelancing individually to working with teams in digital agency and startup — which helped me develop strong adaptability and teamwork skills.
Most of my career has focused on building and maintaining WordPress websites (custom themes, ACF, Twig, Gutenberg), but over the past two years I’ve also been involved in React/Next.js projects. Recently, I’ve taken a growing interest in backend and AI development through my work at Onconest, an AI-powered health startup, where I contribute to both backend and AI implementation.
I’m passionate about clean, accessible web experiences — over the last year, I’ve led accessibility improvements for large-scale projects in a US-based digital agency. I’m always eager to learn, improve, and take on new challenges where I can deliver results and make an impact.
Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.
We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Ascento | Zurich, Switzerland | Full Stack | https://www.ascento.ai
Ascento develops autonomous security robots that patrol outdoor areas to detect and report. All in support of security guards. We stay away from conflict, just robots driving circles around buildings in remote boring places. The technical challenges however, are far from boring.
We are looking for a full stack engineer to join as a core member of the off-robot software team. This is the software that plans, configures, operates and creates insights from data collected from the robots. You would work across the whole cloud-stack, consisting of Frontend (React), Backend (Typescript / Go), Infra (Terraform / AWS / GCP).
The cloud software team is still small, meaning you get a chance to help set priorities, guide long-term architectural direction and figure out how to best help our users. We celebrate pragmatism, we work hard to make simple systems and we help each other to hyperfocus.
Sounds like the place for you? Drop an email to sijmen@ascento.ai. I'm curious to read what about this ad caught your interest.

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Rapid deployment and iteration of experimental software changes across firmware, control software and UI
- Modelling buildings in code and finding the right UI for operators to edit them
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations and we need experienced, generalist engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Tandem Health | Senior/Staff Software Engineers | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)
We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We’re especially keen to talk to Staff Engineers (backend) and Senior AI Engineers (e.g. LLMs and the scaffolding around, computer-use agents)
Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

Milestone Systems | Lead Data & AI Engineer | Remote (USA)
The Arcules team at Milestone is looking for a Lead Data & AI Engineer to design and evolve the intelligent analytics portion of our security cloud platform. This spans from squeezing the most out of video and data coming into our platform, to building scalable data pipelines, to deploying AI models and agents that power insights for our customers.
In this role, you’ll architect and implement our data lakehouse, transform existing data into high-value “gold” datasets for AI applications, and design the AI systems that bring those insights to life. You’ll work hands-on with cutting-edge technologies including Spark, Iceberg, Trino, Go, Python, and GCP.
Arcules is like a "reverse Netflix": our data pipelines process petabyte-scale incoming video streams, requiring close to real-time inference.

Phrasing.app | Co-founder | EUROPE REMOTE
Phrasing is a bootstrapped company dedicated to building the most effective and efficient way to learn a language.
I’m a polyglot myself and have always struggled for a few main reasons:
1. Apps only ever focus on taking you from 0-1, never from 1-100.
2. If you have any experience in the language, it’s really hard to pick it up after a few years.
3. Language learning apps are always ugly, clunky, ugly, and just stressful to use. And ugly.
4. No apps support maintaining and learning multiple languages simultaneously
5. Apps only ever support the major languages, leaving minority languages in the dust
So, I set off to build my dream language learning application, and a quick 2 years and 10,000 hours later I’d built Phrasing.
It’s launched, it’s live, it has (happy) paying daily users, and I myself am using it to learn 18 languages. The product is ready to go, and the business is already growing organically.
I’m looking for someone cracked to come in in a co-founding capacity and eventually take over the backend (elixir) codebase from me.
No experience is required so long as you’re passionate, talented, and hungry.
If you’re interested, and located in Europe, send me an email at hn@phrasing.app.
Hunh. It feels weird to say "Language learning apps are always ugly, clunky" and "Apps only ever support the major languages, leaving minority languages in the dust" when those are a few things that Duolingo actually does fairly well. Don't get me wrong, Duolingo has a LOT of flaws and I'm excited to hear you're building an alternative to it, just the pitch feels like it's based on a time when Rosetta was the name to beat.
That’s a fair point. It was originally “Those that work are always…” but I lost that preface in some refactoring.
I think it’s quite obvious though why Duolingo doesnt disprove any of my points. There was and is still no pleasant, multilingual, effective language learning app on the market. For the most part, you can choose one of those (and no, I do not consider Duolingo “multilingual” in the sense most polyglots need :) )
Absolutely. One thing you absolutely can’t say about Duolingo is that it’s ugly. Not very clunky either.
I personally find it quite ugly and clunky. I feel like the interface is optimized for children, and the number of ads you have to tap through to get even a modicum of knowledge is quite clunky. The last time I used it I spent over 20 hours to partially learn almost 4 letters of the Arabic alphabet — I’d call that pretty clunky.
Objectively they have a good team, but I do not think it’s above crticism in either regard.
Wish you had Flemish Dutch (Vlaams)
Added! It will be under "Dutch (Belgium)" when displayed alphabetically, but it will appear as "Flemish" in reviews.
I'll work on getting some samples generated today or tomorrow for the onboarding flow, but if you sign up you can now extract expressions in Flemish.
Any chance you would add Dzongkha?
PS: Cool product, if I were in a different life phase I would definitely consider joining you to build it!
It doesn't look like any of the TTS solutions are sufficient. I'll be removing the language limitation sometime next year, once the interfaces are built out for custom audio and custom annotations.
If a good Dzongkha TTS comes out, then I'd be happy to integrate it natively!

Absinthe Labs | Full-Stack Engineer | REMOTE / NYC Hybrid | Full-Time
About us: Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.
The problem we’re solving: Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.
We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.
Why it matters: This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.
The role: We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions

Fusionbox | Python + TypeScript Engineers | United States| Full-time | REMOTE (Legal to work in the US)
We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
I'd be curious what statemachine libs you're using. The open source side of python statemachines is pretty limited (though python-statemachine is rather nice and its repo owner is a pleasure to work with).
Something on the typescript side? I've seen that union types can be rather elegant for representing the structure of a statemachine.
Speckle | Backend (Engineering), Founding Account Executive (Growth) | Full-Time | REMOTE | US East, London, EU | https://jobs.ashbyhq.com/speckle
At Speckle [0], we’re on a mission to shake up the AEC (Architecture, Engineering, and Construction) industry. To do that, we're building the OSS data layer for AEC to operationalize how the built environment industry works with data and automation. Think of us as a cross between Github and Palantir, with an opportunity to significantly impact a $10 trillion industry. Our platform already powers workflows on billion dollar projects at leading firms like Suffolk, Multiconsult, Pomerleau, and Stantec.
I'm the CEO/founder and I can honestly vouch that we're tight knit team that values autonomy and shipping cool product on top of our data layer (me included - and this might be a red flag for some, but it's my therapy) over hierarchy, politics, levels and complexity (my spirit animal is the grug brained developer). We love working together with our customers - construction is truly a unique place where each project is its own micro universe.
We have multiple roles open across engineering and growth (sales & marketing) [1]

Annex | Backend + Data Engineer | Bay Area, Austin | Full-time
The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.
We grew revenue 6x last year and should end 2025 having grown 3-4x. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.
We're in that exciting early stage, where someone can contribute foundational new pieces to core parts of our platform.

HouseAccount | https://www.houseaccount.com/ | AI Engineer | Full-time or Part-time | Remote only (Eastern Time USA)
Say you have a broken pipe, a door to replace, a TV to mount. How easily can you find a handyman to get it done? At HouseAccount we want to harness the power of AI to improve the home services space.
Currently we integrate with OpenAI Platform to ask follow-up questions so handymen can get a thorough description of the issue and provide a quote right away. I am looking to hire a developer to make this integration even smarter, anything from image recognition to recommender systems.
I am the sole developer and I'm looking to be joined by someone autonomous and with a lot of energy. You will be responsible for tinkering with existing LLM models (how to rewrite the prompt to balance tokens and speed?) and for coming up with your own innovative solutions (can a homeowner take a picture of a broken pipe and get an instant quote and availability?).
We are a startup, which means you will work autonomously and you will own the pipeline without any "corporation bureaucracy". Your task is to build something innovative where the outcome speaks for itself.
If this sounds like you, submit your application to https://job-boards.greenhouse.io/houseaccount/jobs/495978200... Written communication skills are paramount so a cover letter is expected. Include "HackerNews" to get screening priority.
Thanks.

Sitch App | Founding Product Manager | NYC-area HYBRID (2-3 days/week in NYC near Union Square) | Full-time
Sitch is a new type of concierge dating app. We're using AI + Humans to ask you questions, get to know you, then help you find love.
We're an AI powered concierge matchmaker for serious daters. Sitch is live in 5 cities and expanding nationally in 2026.
We're philosophically opposed to the dopamine-fueled mini-game doomswiping of 'traditional' dating apps which cynically monetizes desperation. We're monetizing intent!
* We're top-tier VC funded (a16z Speedrun, M13, early Snap angels) * Looking for a PM who loves building for consumers, loves relationships, is a bit unusual, and is obsessed with building unique experiences only made possible with the new era of LLMs
* 2-3 days/week in person, in Manhattan near Union Square
Site is at https://joinsitch.com, and feel free to send me (Chad) and Dini (co-founder) a note at hi@unusual.inc
How are you dodging the cross-concerns of 'people who use the app more are more likely to dump money into it'? At present, customers who pay are more desperate than customers who don't, so income is directly tied to customers who can't find a partner.
probably a longer answer is warranted, but we keep it simple - everyone pays - which essentially eliminates ghosting and self-selects for people who are serious about a search for a partner.
Excellent gate. This weeds out attention seekers, as well.

Lantern | NYC only, hybrid 4 days a week in office | Senior Software Engineer (mid career - Staff)
Lantern is Series A company, building the future of sales automation with AI agents that actually work. We're replacing the messy patchwork of enrichment tools, intent platforms, and automation software with a single system that does it all—pulling from 150+ data sources to research prospects, verify contacts, and help close deals.
We're a small, focused team tackling hard problems at the intersection of AI and enterprise data. You'll be working directly on the core product, helping us build intelligent systems that can reason about complex sales workflows and make autonomous decisions.
On any given day, you might:
- Build reliable agentic workflows that orchestrate multi-step research and outreach processes
- Design data pipelines that synthesize insights from hundreds of disparate sources into actionable intelligence
- Architect systems that scale gracefully as we handle increasingly complex prospect analysis and verification
- Collaborate directly with early customers to understand how our AI agents can solve their hardest go-to-market challenges
Tools we use:
- Python, LangGraph, BAML, Temporal.io, ClickHouse, Postgres, dlt - TypeScript, React - AWS, Modal.com, K8s, ArgoCD, GitHub Actions
This is a chance to work on genuinely novel problems in AI—not just fine-tuning LLMs, but building autonomous agents that can navigate messy real-world data and make smart decisions. If you're excited about pushing the boundaries of what AI agents can do in production, we'd love to talk.

Goblins | https://goblinsapp.com | Founding Engineer #3 | Williamsburg, New York | ONSITE | $100-200k (+ generous equity)
In education, we have always traded off scale and quality. In a 30-student math class, half of kids are ready to accelerate while half are still working on their foundational skills, but teachers cannot be in 30 places at once, giving each student one-on-one support.
Until now. Imagine 30 teachers in every classroom—that's how Goblins feels. Students draw math on any device, and our AI figures out the "why" behind their confusion, giving instant feedback and building conceptual foundations. (Try it out here! https://app.goblinsapp.com/onboard)
Goblins launched to school districts in the spring of 2025. Since then we've built a waitlist of thousands of teachers and sold Goblins to districts across the US (we'll hit 100k+ paid students this year!). We are in the unique position of having a product that is both highly differentiated and demanded :)
Technical problems that we find interesting:
→ Building knowledge graphs that adapt to student performance in real-time, routing them to the optimal next problem they should solve to maximize learning and engagement.
→ Extending our handwriting recognition from digital canvas to real paper through Chromebook cameras (think real-time OCR on math equations through low-quality webcams with poor lighting)
→ Creating interactive mathematical lessons (think 3blue1brown, but conversational) that remediate student misconceptions.
You'll be joining founding team members Sawyer (CEO, former Head of Design at X1 [acquired by Robinhood] and math teacher) and Alp (CTO, ex-Stripe and Amazon), plus two other exceptional founding engineers.
We move fast, care deeply about craft, and obsess over delighting users. If you're interested, email alp@goblinsapp.com :)

New Hedge fund | Full Stack Engineer | On-site (NYC)
We are a new discretionary, tech industry focused hedge fund, founded by a portfolio manager with 15+ years of experience at a Tiger Cub. I lead the data/technology team here and previously spent ~6 years in a similar role at a well known Tiger Cub and briefly running a data startup.
We are hiring for: - Fullstack engineer for our internal research management web application
Our tech stack: * Frontend: Typescript, Vue3 * Backend: Cloudflare, Supabase/Postgresql, Typescript *
On the data side: AWS, Cloudflare, Snowflake, Clickhouse, Dagster
Obviously, we are not the only ones trying to figure out how to use AI in investing but in a world where there are lots of people trying to build picks & shovels, this is an opportunity to be one of the goldminers at a greenfield, new firm. This role makes sense for people who are interested in finance/investing (although you do not necessarily have to have experience in the industry).
We're in full-time in office in NYC, so that's a requirement for FTE.
We work very hard, hours are long, and people are very dedicated to the mission. It is not for everyone, but for those interested in competing in financial markets, love startup atmosphere without near-term existential risk, and want to work with super smart colleagues (both technical and investors!), this could be a great fit.
I write about hedge fund data teams frequently here, if you are just interested in learning about the space: https://magis.substack.com/
Target salary 180-250K, depending on experience + Bonus/Carry (hedge fund equity equivalent)
Contact: I am at: ai (at) nx1 (dot) com (I'm Alex, ai are my initials... you are not being sent to an ai :] )

What we're looking for: - 4-8 YoE in Typescript (we use Vue) + Python experience - Ability to be in-office in NYC - Bonus: SQL (ie. you know Window Functions), AWS (ie. you'd know how to configure an IAM role)
Not sure what the email is - you're missing the user part?
AFAIK, emails can't start with @
Yes it's a bit confusing for multiple reasons but I think it's ai at nx1 dot com.
Hi sorry -- it is: ai (at) nx1.com
If you can’t work out the email, you won’t get past the interview, sorry.

We are building a new programming language (BAML) to build AI agents -- the "typescript" for LLMs. We are open source: https://github.com/BoundaryML/baml

We are looking for engineers with experience with Rust, programming languages, and/or compilers. Any amount of experience is fine.

If you believe in ownership, iterative delivery, and building modern enterprise software the right way, say hello.
This may not be the “right” place to ask this, but I am a software engineer in the entertainment industry and it’s pretty bad right now. What is a pivot I can make? My skills are mostly C++ and Python.
It might be better in its own "Ask HN" post.
If you want to get into AI topics: start learning about LLMs, embeddings, vector stores, datasets, fine-tuning, evals, and how to use CLI dev tools like Claude Code.
Andre Ng helped build a great free resource with courses: https://www.deeplearning.ai/ (some are sponsored but still free)
I think a quicker pivot (job wise) would likely be Python web development. They already know Python. Then layer on LLMs when doing that job (with more "runway")

Our stack is written in Rust, with a vanilla JS and templated HTML frontend.
Hey there! I tried finding a way to apply, but was unsuccessful. So, I'll put my best foot forward here!
My name is Logan. I'm a software engineer who works a lot in the PERN stack, but a lot of my interests align with what you're looking for(Pokemon, real world assets).

I'm quite competent with JS and have started taking a big interest in Rust recently.
If possible, I'd love to chat more. Is there a way I could contact you?

Hiring for a full-time, 100% remote role (entire company is remote) for a Staff Software Engineer, working on the ShiftUp platform stack (Python, Pydantic AI, GCP, Temporal Workflows, Turbopuffer, Postgres). You will be one of the first five engineering hires, and you will have the ability to grow and shape your own role.

You'll be working to build all kinds of agents, workflows, and other components to support our features. Our research agents are truly deep, sometimes spending upwards of an hour searching and analyzing information for a single prospect or strategy. Our RAG pipeline is focused on quality, leveraging LLM chunking, metadata and graph generation, and contextual embeddings.
If this sounds like fun, let's chat: you won't be asked to regurgitate leetcode solutions, we'll simply have a conversation and see if there's a mutual fit. Our interview process is lightweight, respectful and moves fast. Competitive salary, equity and full benefits.

Leadership Development – Strategic Partnership (Remote)
Are you an established consultant or a retired executive with a network you're not ready to stop using?
This isn't a job; it's a strategic partnership. We are Relationship Media, LLC, a leadership education company founded by a 20-year law enforcement veteran and former S.W.A.T. commander. We have a proven, "sticky" training program that solves the single biggest problem in organizations today: The Relationship Gap.
We’re not selling abstract theory. We sell a practical, example-driven blueprint for leadership (using our proprietary "Be Like Tony & Don't Be Like Chad" framework) that helps organizations in public service, manufacturing, and healthcare solve their $223 billion crisis of cultural disconnection.
We have the product. We're looking for partners who have the relationships.
The Opportunity: Two Ways to Earn We are recruiting a small team of commission-based partners to bring this vital training to their networks.
1. The Certified Partner (White-Label): This is for independent consultants, coaches, and trainers. We will white-label our entire online course with your brand, logo, and welcome video. It becomes your product. You sell it to your clients and keep a significant portion of the revenue. Stop trading your time for money and add a scalable, recurring income stream to your practice.
2. The Affiliate Partner (Referral-Based): This is for retired executives and well-connected professionals. You make high-level introductions to your network (City Managers, Police/Fire Chiefs, Plant Managers, HR VPs). When we close a deal for in-person or online training, you earn a generous referral commission. You leverage your credibility; we do the rest.
Who We Are Looking For: • Profile 1: The Independent Consultant. You are an HR, OD, or leadership consultant, etc., looking for a proven, high-quality curriculum to sell to your existing clients. • Profile 2: The "Encore Career" Executive. You are a retired/semi-retired leader (e.g., City Manager, Police/Fire Chief, HR Director, Operations VP, etc.) who wants to leverage your network for a flexible, lucrative, and meaningful opportunity.
This is a 100% commission-based partnership for established professionals who understand that their relationships are their most valuable asset.
If you are a high-level connector ready to monetize your network by solving a real-world problem, we want to talk to you.

BuildBetter | Senior Engineer (Backend, Full-stack) | Full-Time | Remote (US) | 170-200k base + equity | Visa Sponsorship not provided
BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, and Posthog, automate the operations work that lets them provide their customers with world-class product experiences.
We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.
Joining us will mean solving hard problems at the frontier of AI adoption, including:
- maintaining performance at scale
- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.
- building agent and workflow systems that automate real work for customers
- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly
- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems
Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python
Benefits:
- unlimited PTO
- $100/mo education stipend
- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work
- health insurance

Railway | Product Design, Customer Success Engineer, Product Eng (full stack)| REMOTE (Worldwide) | https://jobs.ashbyhq.com/Railway?utm_source=DayMzWzJ0P
Tired of trying to beat kube into shape? Does writing YAML to ship code fill you with utter dread? Dream of a future where deploying software is simple, and you don't need an army of infrastructure engineers to build that perfect janky bash script™ to make life easy?
We're Railway, and we think infrastructure can be better. So far we've built out a platform loved by hundreds of thousands of users who simply tell us "Give me Postgres", "Deploy this repo", and we make it happen
Fair warning! The problems are complex: home-rolled hypervisors, cut-above container orchestration, over/under/whateverlay networks, virtio device drivers, edge proxies, IAM that doesn't suck, kitchen sinks - we need to build it and we're looking for likeminded individuals who think this stuff is fun.
Three open roles (apply below!):
+Product Designer: -Apply here: (https://jobs.ashbyhq.com/Railway/6fb07755-acd8-4400-9de3-fa5...)
+Customer Success Engineer: -Apply here: (https://jobs.ashbyhq.com/Railway/dbc51554-cdb8-47d5-8071-5a9...)

krea.ai | Distributed Systems Eng. & Data Engineers | San Francisco (on-site & remote), CA
I'm the cofounder & CTO of Krea (https://www.krea.ai). We are a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and professional creatives. Small team (~24); millions of active users; and raised over $83M from top Silicon Valley investment firms.
We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.
The job:
- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.
- Learn ML engineering from world-class researchers on a small tight-knit team. You’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions.
- Play with huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.
Tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational DBs, PyArrow, etc.)
You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for experience with dist. systems, k8s, and existing ML or data experience (but not required!). Cool side projects are a green flag.

Pareto.AI is in the premium data annotation space, focused on ethical, high-quality data annotation. We work with almost all of the frontier labs. We are a fully distributed, remote-first company with engineering teams spread around the world. Some of us work hybrid from our office in SF. There is essentially no restriction on where you're located as long as you're not from a sanctioned country and are willing to adjust to either a US or EMEA timezone.
We have a few full-time, fully-remote roles available. For those two below, we've recently restructured how we do engineering at Pareto and are looking to be very talent dense. I've hired successfully from HN multiple times in the past, so if you have expertise in those respective tech stacks I'd love to chat:
* Lead/Senior+ Backend Eng: https://jobs.ashbyhq.com/pareto-ai/569f4da0-801c-433a-978f-5...
* Lead/Senior+ Frontend Eng: https://jobs.ashbyhq.com/pareto-ai/47552c42-82c1-4bcd-a1f7-e...
We're also looking to hire some shorter term contractors. We have a couple of projects around refactoring and migrating to a new design system, as well as some shorter term projects around compliance, so if you're only available for a short time we'd likely have room for you too:
* Short term/Contract -> Mid-Staff level Front/Backend/Full stack Eng: https://pareto.ai/careers?ashby_jid=4cbdb231-c7c5-40cd-ad9d-...
Backend code-writing roles require a really strong command of Python. Equally for the frontend roles you really need to understand your TypeScript and React. You're expected to have a lot of responsibility.
No recruiting agencies or similar.

You can reach me directly at steven@[domain] if you have any questions that aren't covered by this post or the job listings, but any applications would need to go directly through the link above. After you have applied, feel free to drop me a one-liner email with the subject "Via HN: Applied" letting me know so I can make sure you don't get caught up in the screening flow.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS product or AI wrapper, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.
Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool new AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

Role
- Software Engineer (#5 on the team; ~20% of eng capacity). High ownership, product-minded, backend and systems leaning.
- You’ll ship fast, prune scope, and help shape our engineering culture.
- You’ve thrived in early-stage environments, can tackle fires independently, and care as much about product as code.
- Strong backend experience; generalist who enjoys moving up/down the stack.
- You care deeply about user privacy and data security.
Stack & ways of working
- .NET (C#) backend, React + TypeScript frontend, Azure, GitHub CI/CD.

How to get in touch
Reply with your GitHub/LinkedIn + a few lines on what you’ve built, or email jp@trinsic.id.
If you’re North America‑based and excited about identity, I’d love to talk.
JP, CTO @ Trinsic
Your comp philosophy: principle #1 - transparency. Specifically mentioning not revealing details long into a hiring process as a bad practice.
Your job req - no comp range provided.
Why?
Since we do location based pay (based on benchmarks) it's tough to give a range as it'd be a huge range (North America has a significant variety of pay scales), and the various levels themselves in just the US have big ranges as well.
We'll address this in our first orientation call with a candidate to make sure we're in the same ball park of ranges.
But point taken, we'll look into if we can make some range indications available. For now, if you lookup compensation ranges for companies in our peer group and your geography it should match, but very happy to discuss your specific during a call.
So work provided to you is worth different money if it's done from NY vs Berlin or Paris, why?
We can have a great philosophical chat about it! Let's chat.
it's philosophical only in your head. In real world if you are geared towards exploiting people you will always find good enough explanation to make you feel better. In this case that reason is location.
MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time
MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.
We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

I’m Kiran, Chief of Staff (CoS) at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
Applied :) Hopefully you're open to Rubyists who are keen to explore other languages/ecosystems!
Edit: Mixrank
Sounds familiar. This is the company that wants to pay ~$2k a month and is looking for engineers in the third-world. They will also deny you if you are in the US and looking to put something recent on your resume and don't care about salary.

That doesn't doesn't like a job posting. That sounds like a request for free consulting.
Is there a role open, with expected responsibilities and a compensation level you can communicate?

I'm getting it from the fact that you aren't showing people a job posting. Nor are you asking about their experience. Your application process is to send you ideas for growth. That is why it sounds like free consulting.
I know the kind of person you are looking for. I am that type of person. And I'm telling you there is no way I'd download an app and send my ideas in as part of a job application. I'd gladly do so as a small paid gig during the application process, when we have talked and it feels like my experience matches your needs. But not as the initial contact, no way.
Novig | Multiple Roles | New York | Onsite | Full-time
Novig is rebuilding sports betting from first principles as a prediction market exchange. Legacy sportsbooks are extractive middlemen with misaligned incentives, dark patterns, and predatory mechanics. We're creating the alternative: a transparent exchange where users trade against each other at fair odds.
We're building core infrastructure around order routing, risk management, data pipelines, low-latency networking, and market integrity at scale. We write Rust extensively. We believe correctness, performance, and expressive code are necessities rather than luxuries. Ideal candidates care deeply about infrastructure, security, and performance. It certainly won't hurt to also care about prediction markets, traditional markets, or well-designed distributed systems.
Tech stack: Rust, Node, PostgreSQL, Kafka, Linux, distributed systems.

About me: Hi, I’m Giorgi — a Full-Stack Web Developer with around four years of experience in frontend development and about a year in backend and AI-related work. I’ve collaborated in various settings — from freelancing individually to working with teams in digital agency and startup — which helped me develop strong adaptability and teamwork skills. Most of my career has focused on building and maintaining WordPress websites (custom themes, ACF, Twig, Gutenberg), but over the past two years I’ve also been involved in React/Next.js projects. Recently, I’ve taken a growing interest in backend and AI development through my work at Onconest, an AI-powered health startup, where I contribute to both backend and AI implementation. I’m passionate about clean, accessible web experiences — over the last year, I’ve led accessibility improvements for large-scale projects in a US-based digital agency. I’m always eager to learn, improve, and take on new challenges where I can deliver results and make an impact.
