Founding ML/AI Engineer

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.
