Fredrin | Forward Deployed Engineers | Los Angeles, CA | REMOTE | $150k-$250k annual salary

Fredrin is an AI software factory for engineering teams: run many coding agents in parallel from one Kanban board, with each ticket getting its own branch, worktree, and agent session. We bring planning, execution, code review, and pull requests into one workspace. https://www.fredrin.com

We're hiring forward deployed engineers to help teams adopt Fredrin in real production workflows. You'll work directly with customer engineers, connect their repos and CI, make their codebases agent-ready, debug deployments, and turn what you learn into improvements you ship in Fredrin itself.

We're looking for strong TypeScript skills, deep practical knowledge of Git and worktrees, experience shipping production software, and hands-on experience with AI coding agents. You should be comfortable owning ambiguous problems and communicating clearly with customers. Try Fredrin before applying: you'll be teaching it from day one.

Rebar | Software Engineers (Product, Applied AI, ML Infra, Data Platform) | ONSITE 5 days/week, New York City (union square area!) | Full-time | $150k–$260k + equity | https://jobs.ashbyhq.com/rebar

We build AI estimating software for commercial HVAC, plumbing, and electrical contractors. Before bidding on a job, a contractor or estimator has to count every duct, fitting, diffuser, and piece of equipment across a set of construction drawings that can run to thousands of pages. We speed this up by ingesting the drawings, detecting the equipment schedules, finding symbols, and producing a priced takeoff that the estimator reviews and corrects in a collaborative canvas editor. We have strong PMF and raised a $14M Series A earlier this year.

It may not sound sexy, but it actually is!! There are a ton of hard and interesting engineering challenges. Just to highlight a few:

* very dense document drawings with a realtime collaborative canvas editor (think 50k DOM elements and up) * segmentation models (and many more) whose output has to become geometry a user can interact with * gpu inference across hundreds of concurrent jobs * dynamic analytics and chart generation from agentic workflows custom built for estimators

Open roles:

* Software Engineer, Product ($180k–$240k): https://jobs.ashbyhq.com/rebar/5ab49c2d-9a70-4723-9217-7704a... * Software Engineer, Applied AI ($150k–$250k): https://jobs.ashbyhq.com/rebar/ad41a627-d9a4-49a4-a1b4-f7202... * Software Engineer, ML Infrastructure ($200k–$260k): https://jobs.ashbyhq.com/rebar/ead8df0c-b6da-4e79-90d0-99651... * Software Engineer, Data Platform ($170k–$220k): https://jobs.ashbyhq.com/rebar/c227ea05-98f8-4a08-9760-f7e3c...

Stack: TypeScript/React/Next.js, Python, PyTorch, Postgres, Temporal, AWS, Kubernetes, Modal.

We're also hiring for PMs, implementation, sales, and marketing roles! I'm the Head of Engineering. Apply through Ashby and mention HackerNews or HN in the Ashby form. Or email me at john@withrebar.ai. We will reply to everyone, but it might take us some time! Thank you in advance for your patience

Additionally, there's a fun puzzle on our marketing site that will fast track your application if you want to solve!

Estee Lauder Companies | Staff Machine Learning Engineer | Long Island City - NY | Hybrid | Full-Time

As a Staff Machine Learning Engineer, you're a player-coach: a strong hands-on contributor who also sets standards, reviews others' work, authors the designs others build against, and mentors the team. You design, build, test, and deploy production AI products and the platform beneath them, and you shape how we build and integrate AI systems — working with engineers, scientists, product managers, and domain experts to turn ambiguous problems into reliable, scalable deliverables. The core of this role is engineering: agentic AI products and their platform, including stateful, transactional services where reliability and data-modeling rigor matter. Classical ML, statistics, and experimentation are valued and let us take on predictive and inference work when the roadmap calls for it — but you may spend long stretches purely on AI-product and platform engineering, so we're looking for someone energized by that work.

Interview process: Recruiter call, meet hiring manager

https://careers.elcompanies.com/careers/job/1168273194779

So people are basically only interested in hiring seniors? Jesus. We really are living in the worst possible timeline. Christ almighty. Thank you all for making the professional ambitions and dreams of IT enthusiasts and students living nightmares.

Proxima Fusion | Senior Software Engineer (Dev Platform) | Munich, Germany | ONSITE | Full-time

We're building the world's first commercial stellarator fusion power plant. First spin-out from the Max Planck Institute for Plasma Physics, based on Wendelstein 7-X (the largest stellarator ever built), €650M+ raised, teams in Munich, Zurich and Oxford.

Finding a good stellarator design means searching an enormous high-dimensional space, and every candidate design needs heavy plasma physics simulation. That's the compute problem this role owns: cloud + HPC clusters, K8s, Ray, Dask, and the platform work around it (CI/CD, IaC, observability).

You'd sit directly next to the physicists and AI researchers burning through that compute, so you see exactly what your infrastructure unlocks. Python and Linux.

If you've wanted to point your platform engineering skills at something that actually matters, clean, abundant energy, this is about as direct a shot as it gets, and it's happening in Europe.

Interview process: recruiter call, meet the team lead, technical panel, meet the CEO.

Flok Health | Multiple roles | ONSITE | Cambridge UK | Series A

https://www.flok.health

Come help us build explainable AI for providing physiotherapy at scale.

Our core systems are a custom decision engine, interactive streaming video over WebRTC, and multiple internal tools to help us scale. We care a ton about high quality software and great UX - healthcare apps has a bad rep for being unpolished. Commercially, we partner with national healthcare systems to provide high quality care that patients love.

Over the next 18-24 months we are expanding our geographical and product footprint:

- Our infrastructure will need to mature - Our software will need to generalise as we treat more clinical conditions - Our collection of internal tools will need to grow

We're hiring for generalist engineers. Our core stack is Python/Rust/Typescript, but all backgrounds welcome as long as you like ownership and responsibility.

Read more and apply at https://www.flok.health/careers/engineering-team or find me online and DM me! We're 4 days a week on-site in a beautiful farm-style office in Cambridgeshire.

Definitely mention you came from HN if you apply - will help you stand out against the flood of AI-generated applications we get these days.

Search Atlas | Product Engineer (Product Manager role, not a Full-stack role) | REMOTE (anywhere, EST hours) | Full-time contractor | $23-$34 USD/hour | https://careers.searchatlas.com/jobs/599248-product-engineer...

We're ~160 people, fully remote, building an AI marketing platform. Our main product is OTTO, which runs a site's SEO on its own - it reads live search data and pushes the technical and on-page fixes itself, nobody queues them up. Around that we've got ad automation for Google and Meta, GBP management for multi-location brands, content gen, and LLM visibility tracking (whether ChatGPT and co are citing you). Autotrader, Hyundai, P&G, Vendasta are some of our customers.

Work happens in pods, 1 PM and 2-4 engineers. You own your pod's roadmap and ship it with them, no veteran PM signing off on your specs first. That's the part most PM roles won't hand you.

Looking for 3+ years PM in B2B SaaS with an actual technical background - eng or QA before PM, or a PM who's been getting into the codebase themselves. You should be able to read Python and TS, write your own SQL, find your way around an API, and not need an engineer to tell you what a stack trace says. We're Django on the back, React/Next on the front. QA is yours end to end including release sign-off, people tend to underestimate that bit. And you're already using Claude Code or similar daily, not "open to it".

A few notes before you apply:

- Experience: we're looking for people with a few years of hands-on product or engineering work behind them. The role is autonomous from the first week, so we need you ready to take the wheel. - Recruiting agencies: we hire in-house and manage every application ourselves, so there's no need to send candidates or reach out about partnerships. Thank you for understanding! - If your stack matches, please do reach out. Django/DRF/Celery/Postgres with React/Next, Python automation work around SEO: if that's your day-to-day and you're using AI coding tools (Claude Code, Codex, Cursor, whatever you like) in your real workflow, I want to hear from you. Don't talk yourself out of it because the title isn't an exact fit; tell me what you've built.

Recruitment process is screen with me, a take-home that runs about 75 mins, technical round with one of our senior PMs, then a call with our Director of Product (who you'd report to). I usually come back to people within 2 business days.

Our ATS forces us to list specific ywhere as long as you can do EST hours, so apply even if yours isn't

Apply at the link and mention HN somewhere, in your pitch or wherever it fits. joao.pedro@searchatlas.com if you need me, though the link's faster.

P.S: Not a PM, or the PM role isn't quite your thing? Have a look at everything else we have open at https://careers.searchatlas.com and apply directly to the role that suits you best (preferred route). If you're not sure which one that is, email me with a short line on what you do and I'll point you to the right one.

Lokker.com | Data Scientist, Classification and Scoring | REMOTE: North America / Europe, UTC-8 to UTC+2 | Full-time

Lokker is a privacy platform. We continuously analyze websites, applications, third-party technologies and data flows to identify privacy, security and consent risks in production. We have built a large proprietary dataset from years of observing real-world digital behavior, and we are hiring a data scientist to help us expand and improve the classification, scoring and risk intelligence built on it.

You will develop and improve models that classify digital activity, identify meaningful privacy and security behaviors, and assess the confidence and significance of findings.

Looking for 2 to 4 years of production experience in data science and machine learning. Strong Python and SQL, pandas or Polars, scikit-learn and modern classification techniques, familiarity with model evaluation and explainability. Practical experience in training and evaluating supervised classification models on real PRODUCTION data, practical LLM experience beyond simple demonstrations, and curiosity about how websites and internet technologies actually behave. You do not need a privacy or adtech background. We will teach the domain.

You will work closely with engineering, product and privacy experts, and what you build goes directly into the product.

IMPORTANT: the timezone range above is a hard requirement, not a preference. We cannot make an exception.

ON APPLICATIONS: we assume you used AI to help write it. So do we. What we cannot do is verify a claim that exists only in the document you sent us, so make sure the skills you claim are visible somewhere public: LinkedIn with real dates and role detail, GitHub, papers, Kaggle, a writeup, a talk. If your best work is under NDA, say so and describe it in your own words.

A human reads every application. No keyword filter, no automated rejection.
