Ai2 / Allen Institute for AI | Senior Software Engineer | Seattle | Onsite

We're hiring a senior software engineer for AI for the Planet at Ai2.

We build production ML systems for conservation, oceans, climate, and Earth observation. The work is very applied: satellite imagery, geospatial ML pipelines, agent systems, and products used by researchers, governments, and conservation organizations.

Looking for someone who enjoys building end-to-end systems, shipping production software, and working closely with researchers and users.

Comp: $126–189k base + bonus + benefits.

Apply: https://job-boards.greenhouse.io/thealleninstitute/jobs/7909...

Inferra | Founding SRE + Bare-Metal Infra Engineers | San Francisco / REMOTE | Full-time

We're looking for cracked, optimistic engineers/students with good systems taste. We're a team of ~10 in SF, building a GPU neocloud.

The work spans SRE, bare-metal automation, datacenter bring-up, GPU clusters, storage, networking, security, IaC, and Kubernetes-as-a-service. Prior DC, neocloud, and cloud-provider experience is very relevant.

Email sasan at inferra.ai with anything relevant.

Opaxa | Founding Full-Stack Engineer | San Francisco | Full-time | $200K–$300K + founding equity | opaxa.ai

Opaxa is the AI agent platform that runs restaurant back-office operations. Not another dashboard — agents that take the work off the operator's plate and act: build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, draft the review reply. The operator approves what matters; the rest gets done.

The unfair part: the founder owns and runs a 40-location restaurant company with over 750 employee's — so Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Deep domain expertise is built in, and your work runs in real restaurants immediately, not after a six-month hunt for a design partner. Well-funded.

A working prototype is already built. Now I'm hiring a founding full-stack engineer to take it from prototype to production: own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), set the technical bar, and grow the team behind you.

You'd work directly with me — I own product, customers, and the domain; you own the AI and the build. We'd be hiring additional engineers and account managers within the first year.

You're a fit if you: - have shipped agentic systems to production — plan-and-act, not chatbots or wrappers - are a strong full-stack builder (Python and/or Node, Postgres, real infra) - use the latest AI tooling (Claude Code / Cursor) as your default want to own a whole product as the first engineer, and eventually lead

Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, integrations across the restaurant stack.

To apply: email me at colton@opaxa.ai with the most impressive agentic system you've personally shipped — what it did, what you owned, and what made it hard — plus your resume or links. I read every one and reply. Please write it yourself; if it's clearly AI-generated, I'll pass.

z0.ai | Full Time | Founding Engineer | On Site 5 days a week | NYC | $140-$180k USD + equity

We're helping non technical users adopt AI by making usage visible. Power users become role models and people can upskill to gain value rather than lose their jobs to AI.

It's a complex problem because we need to balance trivial UX, with a slew of security and compliance requirements.

This is the first non founder developer role on the z0.ai codebase. We need someone who can own the full stack end to end: product surfaces people enjoy using, services that stay correct, and the taste to make both feel like one product.

We're funded and are live with our first customer already. We expect to onboard our next customer later this week and are actively ramping up sales efforts.

Check out the full job posting at https://www.z0.ai/careers/founding-engineer/ and send an email to join@z0.ai

Paymail | Engineer | REMOTE | Startup Equity Only

Paymail is an invoicing and money transferring service over email. Because it's alot easier to send $50 to email@example.org than to send it to a long series of digits representing a branch and account number. In a way Paymail is an internet native payments competitor to x402.org. I'm the founder and I'm on a mission to make every bank your email provider. I spent the last year working for a banking outsourcing company and it gave me some good insights into what's possible in the FinTech world. I'm currently searching for a React+Typescript developer with good design instincts to give a huge chunk of equity to and become a cofounder of the company working with a well written medium sized React+Typescript codebase that represents our product.

Startups are busy but to get the product to an MVP stage is not very far away at all so it would suit someone looking for a potentially profitable side hustle or on a full time basis as well.

Stack: Stalwart, React, Typescript, Python, Rust, Postgres

Coop (https://smart.coop.farm)| 2nd Founding Engineer | iOS Heavy Engineer | Hybrid onsite | Austin, TX | Full-time, Part-time

My name is AJ Forsythe and I'm the Founder / Chief Chicken Tender at Coop! We're an Austin TX based company on a mission to build the world’s largest decentralized food production network, starting with AI powered chicken Coops. We’ve been in the market for about 18 months and our customers are in 48 states and will generate about >10M eggs this year. It's insanely fun to work on and we have a shot at building a huge business in the connected urban farming space. If you’re big into computer vision, consumer products that are fun, and an awesome team we would love to chat. The Coop has an automatic door + cameras doing computer vision work (predator detection, egg alerts, remote health monitoring, etc). It's a super exciting time and are seeing directional product market fit which I'm thrilled about. Seriously go check out our website, it's a super fun + amazing product.

We’re a tight-knit team of 5 people with 15+ years of experience working together. We’ve been through YC, started and scaled multinational million-dollar businesses together, taking them from idea to acquisition by a Fortune 50 company. We’re gritty and passionate without taking ourselves too seriously - and we’re here to build something really exciting that helps people reconnect with their food and the planet. We're VC backed (call it $5M) by some of the world's best investors but we are a scrappy small team that moves fast. We have an absolutely fantastic CTO Ryan that I'm looking for his / our right hand person to work alongside with. I think the term full stack is overused but that's closest to what we're looking for. Also this really isn’t a traditional Eng role, I look at it as we’re a small growing team and you would be one of us working on a ton a cool projects on day 1. Also, we LOVE working with founders so if you've started a company before that's epic.

Oh also, I have a fun project where I want to make a water gun turret that uses our cameras to detect predators and allows you to aim and blast them. If you're into hacking robotics and gimbals etc, please reach out.

You can also reach out to me directly at: aj[at]coop.farm - Just email me your LinkedIn / GitHub / portfolio + why you think you'll be an awesome fit and I'll respond. Please don’t use GPT too much. This is my 3rd company (2 have exited) and I want to build the super solid core team and you might be the perfect fit for us and vice versa. Bwok Bwok! AJ

FeedbackPulse makes employee engagement simple with tools for creating meaningful surveys, gathering staff feedback, and building a better workplace culture. Our platform offers engagement surveys, performance reviews, and 360° feedback solutions that help companies address high turnover rates and disengaged workforces.

You: HR/PeopleOps experience, using AI tools like Claude Cowork daily, clear writing skills, self-directed, and results-oriented.

Our culture: Direct communication, focused deep work, clear work-life boundaries, and sustainable growth as a bootstrapped company.

Mention you are from HN in your application message.

I'm Roman, co-founder of 9 Mothers. We're building AI weapon systems in Austin, TX. Our first product is designed to stop group 1 suicide drones. We started in 2025 and are still a small team of fewer than 20 people.

We're hiring for a lot of roles, but mostly in software and robotics. I'm primarily focused on robotics, so if you have a strong background in robotics, reach out to me directly at (name)@9mothers.com.

Charge Robotics | Multiple Roles | Full-time | Onsite | SF Bay Area

Hi HN! We’re a YC-backed, Series-A startup building robots that build large-scale solar farms.

Check out a video of our first system here! https://youtu.be/ZZ2fP1Y5Z2E

It turns out that construction companies literally can't build solar fast enough, so what we're doing is a crucial part of switching the grid over to renewable generation.

You’ll be a key contributor, helping bring our next generation of mobile solar factory to life.

Come work with us if you love:

* Fast-paced prototype development with software and hardware components

* Making a positive climate impact through your work

* Hacking on massive construction equipment!

Reddit (YC 1) | reddit.com | Staff MLE | Full-Time | Remote (US) (ideally east coast) | $230K - $322K base + equity

We are looking for a staff MLE to join the Ads Content Understanding team. This team looks at all of the reddit content in order to understand what people are talking about. We own the knowledge graph for the entire company, and we also produce a number of interpretable signals that are then used either for RAG type products or as features for models. This is a horizontal/platform team, all of our customers are internal, and most of them are within the ads space, but we're doing some interesting things with organic shopping experiences on reddit.

There's a lot of upside to this role, we're still nascent on our 'commercial intent' understanding (think - is this post comparing tokyo vs kyoto, or is this post at a later stage in the trip planning journey, it is comparing hotels in kyoto).

The job posting does a solid job of describing the responsibilities and expectations for this role. It's a mix of modeling, engineering, leadership. Please apply if you think there's a good fit, the ideal candidate has both leadership experience as well as domain experience with content understanding.

Team is roughly split into two pods, knowledge graph (mostly EU eng) and signals (mostly US eng). This would be a TL role for the signals pod, so east coast timezone would have the most overlap with our team and partner teams.

We also have an open Senior MLE headcount for this signals pod, and are expecting more headcount in Q3.

Long Tail | full stack | REMOTE/US Based | full time

We build software to help hospitals fight insurance companies.

Small team that just took investment from PE firm so we're scaling rapidly. Looking for AWS-native full stack architects with 5-10 years' experience. No healthcare background required (always a plus though).

Forward Deployed Engineer - backend - python | REMOTE (UTC -3 to +3) | Full time

Small stealth team in the property management space, building AI agents that run real operations, where agents and humans work as one team rather than as user and tool. Funded, profitable, fully remote, competitive comp.

We want a senior backend engineer to own a client facing use case end to end: build the backend tools and workflows our agents call, handle the jurisdiction and client specific extensions, and talk to the client directly. Pull requirements, explain the tradeoffs, own the relationship. Take messy real world problems, turn them into something agents can actually use, then keep it alive in production.

You're probably a fit if:

- you've shipped serious backend systems in production

- you can hold your own on a customer call

- you've run LLM agents in production, or you'll ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call

Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain and LangGraph, prior customer facing or operator background.

We care more about what you've built and can build than a checklist, so skip the skills inventory and tell us about something hard you shipped.

Apply: email mercedes@kinxshn.com with "HN - Forward Deployed Engineer" in the subject , your CV attached and salary expectation.

Lysk | lysk.ai | AI/Geo Engineer | Full-time | Warsaw / Paris

Lysk is a European defence startup, based between Paris and Warsaw. Our mission is to create modern software tailored for hostile environments. Our customers include European military and police units. We are in stealth but have already been recognised as one of France’s top 20 seed companies. Backed by Project A, Europe’s leading defence VC, and angels including the founders of Cloudflare, Quantum Systems, and ElevenLabs. We’re assembling a world-class team at the intersection of modern software and defence. We do not work on weapons systems or hardware products.

Currently we're looking for:

- Junior LLM engineer (gguf, on-prem models, llm validation and pipelines)

- Junior Voice AI engineer (we need customised STT models)

- Senior GEO-AI engineer (interpreation of speech-based geographical information)

Strobe Power | Founding Engineer | ONSITE (Brooklyn or SF) | https://strobepower.com

AI data centers are creating a massive new wave of electricity demand, and the grid is already stretched. Strobe is building an autonomous power company to help meet that demand: software that turns buildings, batteries, EVs, and generators into a distributed power plant that can buy, sell, and dispatch electricity in real time.

We’re a 6-person, well-funded team backed by top investors. This is early, high-ownership, and very real-world: the software you build will control physical assets and move money in energy markets. We are the only company actively trading distributed power in New York - the space is entirely new and unlocked by recent FERC regulation.

I’m looking for a staff engineer to own the data integrations and cloud infrastructure that make the whole system work. That means connecting to utilities, grid operators, OEM hardware, weather providers, and our optimization engine — then making sure it all runs reliably when market events are happening and dollars are on the line.

You’d work on things like:

* Wholesale market integrations with NYISO, CAISO, ERCOT: pricing, capacity markets, dispatch signals * OEM hardware integrations for monitoring, control, and telemetry * Utility data pipelines, including Green Button Connect / ESPI, interval usage, billing, and meter data from utilities like ConEd, PG&E, and SCE * Weather forecast pipelines feeding our scheduling engine * Event-driven AWS infrastructure using Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, Timestream, Amplify, and CloudWatch * Terraform IaC, observability, alerting, and the reliability work needed when downtime has real financial consequences

Good fit if you have deep AWS experience, have used Terraform seriously in production, and write a lot of Python. Energy experience is a plus, but not required. Experience with utilities, government APIs, OEMs, hardware, telemetry, or other “real world is messy” systems is very relevant.

Stack: Python, TypeScript, Rust, Terraform, AWS, GraphQL/AppSync, MQTT, Grafana. We use an AI-agent-optimized monorepo and are investing heavily in agent-enabled engineering efficiency.

Small team, no layers, high trust.

Apply: keeley@strobepower.com or https://strobepower.com/careers. Please mention Hacker News.

I've decided to no longer post here after the incredible amount of spam I started receiving, both in terms of direct email submissions as well as unqualified and outright fraudulent applications to my application tracking system.

By fraudulent I mean: fake resumes, names stolen from real developers who work at well-known companies but either don't have a linkedin/portfolio or do have a linkedin/portfolio without a profile picture. So easily impersonated by a scammer.

It is a real shame, but this thread is now being scraped by plenty of other sites and bad actors.

Inbound hiring for remote teams is basically cooked at this point, signal is completely hidden in the noise. Curious if anyone else has had this experience or if it's just me?

Trax | Analytics Engineer | REMOTE CST (Philippines, Costa Rica, US) | Full-time Contract

We're hiring an Analytics Engineer to help power our future. This is a really greenfield project where we need to define the data models that fuel all reporting, analytics, and ML/AI going forward. We do 'freight audit' - we save our clients money by making sure all their logistics spend is correct and as agreed.

At Trax, our data infrastructure is in the middle of a real transformation. We're building the data foundation that will power our next wave of AI features, and we need someone who can own that work end-to-end. This isn't a "run queries and make charts" role.

You'll be:

- Designing and maintaining data marts in dbt + Snowflake

- Building customer-facing dashboards that integrate into our platform

- Bridging the gap between engineering, business ops, and client teams

- Running ad-hoc analyses that drive real decisions

- Shaping how our data platform evolves alongside our AI/ML capabilities

What matters most to us:

- Deep data modeling knowledge (domain logic, not just syntax)

- Advanced SQL; dbt and Snowflake experience is a big bonus

- Strong communicator who translates between technical and non-technical worlds

- A learning mindset; genuinely non-negotiable for us

We're a small, close team. You won't disappear into a large org. You'll work directly with leadership, partner with Solutions and Sales, and have a real voice in how we build. If you thrive on ownership, are energized by complexity, and want to see the direct impact of your work, let's talk! My email and linkedIn are in my profile.

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering

FusionAuth | Principal Software Engineer, Senior Java Engineer - Cloud, Account Executive, Solutions Engineer | Varies between REMOTE (in USA, also in Europe but only for the account exec/solutions engineer positions) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges for the Principal Software Engineer it is 225k-270k, but the Euro positions don't have them :(

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Fusionbox | Python + TypeScript Engineers | United States | Full-time | REMOTE (US-only)

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 strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), 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 race conditions.

A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you.

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 work 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.

Chestnut | Senior Product Engineer | SF or Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

From our about us: We are builders at heart—founders, SREs, open-source stewards, architects of large systems, and people who love creating things from scratch. We believe AI should amplify the creativity of everyone who builds software, not just speed up tasks. If you’re technical, curious, customer-driven, and want to shape how the next generation of software is created, we’d be thrilled to work with you.

We have multiple open roles, including AI Engineer, Forward Deployed Engineer, and Software Engineers.

Backend Engineer: Postgres-heavy work on Supabase: PL/pgSQL functions, pgmq queues, Deno edge functions, billing and cron systems. You like databases enough to enjoy writing triggers and RLS policies, and you want to own systems end-to-end rather than just ship tickets.

QA Specialist: Manual testing of our iOS/Android app and web tools, working alongside our head of QA on a clinical product where data quality, platform stability, and accessibility are critical to our mission.

Note: Candidates must be in time zones no further west than EST; Western Europe is fine.

Tandem Health | 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 first 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.

We’re expanding our Stockholm team with exceptional builders in a wide range of roles.

Cora AI | Founding Full Stack / Applied AI Engineer | REMOTE (US ONLY, LA/SF preferred) | Full-time | $190–250k + early equity

We build customer success agents and account intelligence that do the actual manual work — so CS teams can focus on the relationship-driven work that drives growth.

You'll be one of the first engineers. You'll ship voice agents, multi-agent orchestration, RAG pipelines, evals, and account intelligence features that touch real customers on day one.

What we're looking for:

- You build with AI IDEs (Cursor, Claude Code) as a force multiplier — not occasionally, as your default

- You've shipped something with LLMs in production (agents, RAG, evals — not just wrappers)

- Comfortable owning a feature from idea to production without a lot of hand-holding

- Based in the US — SF Bay Area or LA strongly preferred

Why Cora:

- Work on cutting-edge applied AI: voice agents, knowledge graphs, multi-agent systems, evals, simulations, and more

- Real users, real impact, high autonomy

- Fast, fair interview loop — no BS

- Fully covered healthcare for you and your dependents

- 401(k) plan

- Flexible time off

Interested? Email careers [at] cora.ai — these go straight to me, and I read every one.

Hotwash | Founding Engineer (→ CTO for the right person) | REMOTE (US), Boston a plus | Full-time

I'm a solo founder. I built the entire product myself, got 11 fire departments paying with zero churn, and now I need someone to own engineering so I can't be the only one who does. West Point, Ranger Regiment, Yale Law, still the only developer.

What we do: Hotwash is an after-action review platform for fire departments. After a serious call, crews record what happened, we transcribe and structure it, and the hard-won lessons become searchable institutional memory instead of retiring when the veterans who earned them do. Fire is the wedge; the long game is operational learning for any high-reliability organization.

Traction: $40K ARR, 11 paying fire departments, zero churn. Raising a $1M pre-seed.

The role: Employee #1 on engineering. You own the codebase, architecture, and UX end to end, and you lead the rebuild off the current stack. You work directly with me on what gets built and why, including sitting with fire chiefs to figure out what they actually need. For the right person this becomes the CTO seat.

Who I'm looking for: A full-stack engineer who ships simple, usable products and has a real eye for design. Our users are fire crews, not power users, so the bar is "obvious to someone who's never seen it." If you care about how software feels, not just whether it works, this is your seat.

Stack: Today it's FlutterFlow + Firebase, Node, with Groq/AssemblyAI for transcription and Gemini for summarization. The rebuild target is React Native (Expo), Cloudflare Workers, D1, R2. You'd own that migration, so this is real greenfield ownership, not maintenance.

Comp: Founding equity, scaled to scope.

We're pre-raise, so cash is lean right now and grows when we close.

Email hiring@hotwash.com with a resume, link to something you've built, and one line on why this interests you.

- Deep understanding of Linux internals, networking, distributed systems, and/or Kubernetes.

- Familiarity with at least one major cloud provider (AWS, GCP, or Azure).

- A builder's mentality: you think about failure modes, observability, and operability alongside correctness.

MixRank (YC S11) | Software Engineers | 100% Remote (Global) | Full-Time

MixRank processes petabytes of data every month through web crawling. Hundreds of customers use our data products, including Google, Amazon, Facebook, Intel, and Adobe, across industries such as finance, recruiting, sales, marketing, and security. We’re a fully remote company with a global footprint across 20+ countries. We’re growing, profitable, employee-owned, and have no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We’re looking for passionate individuals for whom programming is not just a job, but something they genuinely 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 codebase is friendly to new contributors. You’ll have a fully functional development environment within hours through full automation and will be pushing commits on your first day. Deployments to production happen multiple times per day and finish in under two 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 run two datacenters with high-performance servers we’ve built ourselves, capable of handling the volumes of data we process. We’ve implemented our own distributed file system, perform full-scale web crawls, and download and run static analysis on the entire universe of published Android APKs and iOS IPAs.

Unlike a typical startup where you might spend half your time in meetings and the other half fixing Jira tickets, at MixRank you’ll challenge yourself with difficult technical problems that help you grow as an individual. We’re continuously hiring for the positions below; these aren’t singular roles that close once filled. Our philosophy is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities around their interests.

Other companies may create a long list of specific requirements with the expectation that you’ll exactly replace someone on the team or fit a role defined by committee. MixRank is more pragmatic: we first get excited about bringing a unique individual onto the team, then figure out the best way to support their specific talents.

Servicing Copilot | Senior Full-Stack Contractor | REMOTE (EST overlap required) | $5k paid bake-off → ~6 month contract | CAD $130-180/hr

I'm building an AI-native operations tool for private mortgage lenders. MVP targets two workflows that eat servicing staff time: NSF collections follow-up and renewal management. I run a Canadian private lender as my day job, so the product is built against a real shop with real data and real users. Self-funded. No VCs, no board.

The data model is locked (20 tables, multi-tenant by lender_id, idempotent CSV imports, append-only event log). Wireframes in progress. Hiring one engineer for the full ~6-month build via a paid bake-off: $5k flat for ~1 week of work, 2-3 candidates in parallel, winner takes the engagement. Losing candidates get paid in full and keep their work.

Trial scope: CSV loan tape import with idempotent upsert + audit, one case detail screen, one LLM call classifying a borrower email reply with structured output, activity log driven by case events. Stack is contractor's choice — Postgres required, Next.js + TS or Python + React expected.

Looking for senior generalists with real production LLM experience (structured outputs, evals, failure modes — not side-project tier) and strong relational data modeling judgment. Opinions you'll defend in writing.

Email: info@readifinancial.com

with: one paragraph on why this interests you, 1-2 links to shipped work involving a real schema + LLM in production, your rate and availability, and one question about the project. No cover letters.

BIT Capital | Head of Engineering | Berlin, Germany | ONSITE (2 days/week) | Full-time

Looking for the key engineering leader to build and scale infrastructure and data platforms for a Berlin asset management fund. We are betting big on AI to drive investment returns and build the best infrastructure to support our high alpha targets (track record >35% p.a. since inception; https://bitcap.com/en/bit-global-technology-opportunities-ai...).

You'll design large-scale data pipelines, evolve our lakehouse architecture, strengthen data quality and observability, and build infrastructure for AI/LLM workflows (agentic scaffolding, RAG, LLMOps, AI for engineering). We are looking for a hands-on technical leader, that is steering initiatives end-to-end while staying deep in implementation.

We have our roots in tech entrepreneurship (Jan Beckers), and this mindset still dominates our work culture, even as a regulated financial institution. We are a team of 45 tech- & investment experts with a flat hierarchy, hands-on leadership, fast-paced decisions, and a little nerdy culture as people are actually passionate about their work. Stack: AWS, Databricks/Spark, Python, PostgreSQL, Agentic AI.

If the complexity of financial markets excites you as much as the complexity of distributed systems, you'll love it here. Competitive comp, relocation & visa support, stellar team.

Hey HN! Air Space Intelligence (https://www.airspace-intelligence.com) is hiring in Boston. We are a frontier AI and product company for the critical industries and defense backed by a16z.

We’re rebuilding America’s air traffic control system from scratch. What we do in the next two years will define how this country moves through the sky for the next fifty.

At the core is one of the largest real-time optimization problems in the world: how do you safely sequence ~40,000 flights/day while routing around weather, military airspace, equipment outages, and constant real-world churn? The system has to be right every time, and reliable at scale.

We’re hiring across Backend, Infrastructure, and Frontend (ICs and Tech Leads).

One of our roles (with a small puzzle at the bottom that routes to my email): https://www.airspace-intelligence.com/careers/role?=1336c828... - include “HackerNews” in the subject so I can prioritize.

If you want a problem that is genuinely hard, consequential, and urgent - this is the moment to reach out.

Adacore | Software Engineers | Full-time | Remote or On-Site

Adacore is the maintainer of GNAT, GCC's Ada frontend (but now with many more compiler backends: LLVM, Why3, JVM...) and of a lot of tools revolving around the Ada ecosystem (IDEs, Coverage tools, Fuzzers, Static Analyzers, Formal proof tooling...). Evertything we build is open-source and we make money by providing support, trainings, certifications...

We are looking for different profiles:

- GCC/GNU toolchain developpers ( https://app.hellotalent.com/vacancy/gnu-toolchain-developer-... )

- Senior Static Analysis Software Engineer ( https://app.hellotalent.com/vacancy/senior-static-analysis-s... )

Please apply through the website. I am in the Static Analysis team, so I can answer questions if you have any. Also, if you feel like you would be a strong candidate (e.g. you have working experience with abstract interpretation) but are missing some of the requirements (e.g. not in the right location or only three years of experience instead of five etc) and this is making you hesitate to apply, please contact me - I'm just a lowly engineer far removed from the hiring pipeline but I'd love to hear for you and try to convince HR that you could be a good fit :).
