We're seeking a Founding Engineer (AI/ML) with 2–5 years of production software engineering experience and strong applied machine learning expertise. This engineer will own the intelligence layer of client recruiting marketplace, building recommendation systems, ranking algorithms, retrieval capabilities, and LLM-powered matching solutions that improve candidate-role alignment. The ideal candidate has personally shipped production ML systems, writes strong Type Script or Python, and thrives in a fast-paced, hands-on founding-engineer environment.
Job Description:
Job Category:
Information Technology. As a Founding ML/AI Engineer at client, 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.
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. This is the thing we care about most. Strong in Type Script 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 Git Hub, projects you're proud of. Nice to have:
React, Supabase, Prisma, Typesense, trigger.dev, embeddings and vector search.
How we work:
We're in person in SF at our hacker house, 6 days a week. It's an intense cadence and we'd rather you know that now than find out in week two. Relocation assistance available.
Skills and Certifications [note: bold skills and certification are required]. Production recommendation, ranking or ML matching systems.
Type Script or Python production engineering.
Production LLM APIs
