Founding ML/AI Engineer
San Francisco, on-site · Full-time · US Relocation assistance available
The build: As a founding ML/AI engineer, you'll own the intelligence layer of our recruiting marketplace — the
recommendation systems, ranking algorithms, and LLM-powered matching that
decide which candidate sees which role. This is the core of how the product
works, and it's yours to build.
What you'll do
- Own
the AI/ML intelligence layer end to end: recommendation, ranking, and
retrieval.
- Build
LLM-powered matching that measurably improves candidate-role alignment.
- Take
features from problem to production yourself, shipping on a daily cadence.
- Architect
and maintain the production data pipelines and services the models run on.
- Work
directly with the founders to turn product goals into shipped systems.
Requirements
What we're looking for
- 2–5
years shipping production software, with real applied ML depth. You've put
models in front of users, not just in notebooks.
- Hands-on
experience with recommender systems, ranking, or ML-powered matching — the
thing we care about most.
- Strong
in TypeScript or Python. Either is fine on its own.
- Production
experience with LLM APIs.
- Strong
CS fundamentals and a track record in fast, unstructured environments.
- Something
outstanding on your profile: a top program, a strong GitHub, projects
you're proud of.
- Nice
to have: React, Supabase, Prisma, Typesense, trigger.dev, embeddings and
vector search.
How we work: In person in SF at our hacker
house, 6 days a week. Intense cadence — better you know now than find out in
week two. Relocation assistance available.
