Job description

We're looking for a Founding AI Engineer to help build and scale an AI-first product from the ground up. This is a hands-on role for someone who enjoys solving hard problems, shipping quickly, and working across the stack to bring new capabilities into production.

You'll join a small, highly technical team and play a key role in shaping the product, technical foundations, and engineering culture.

What you'll do

In this role, you will:

  • Develop production-grade AI systems that deliver reliable, high-quality outputs in real user workflows
  • Design and maintain evaluation infrastructure (benchmarks, automated tests, monitoring) to measure quality and guide iteration
  • Experiment rapidly and ship improvements by combining LLM prompting techniques with practical engineering
  • Work end-to-end from research and prototyping through deployment, iteration, and performance tuning
  • Collaborate closely with product and engineering to translate ambiguous requirements into robust solutions

What you bring

As our Founding AI Engineer, you've built AI solutions that tackle difficult problems - demonstrated through prior roles, personal projects, open-source work, or a strong portfolio/GitHub presence.

Requirements

  • Expert-level Python skills
  • Industry experience shipping algorithms and/or evaluation pipelines into production environments
  • Hands-on experience with large language models and prompt engineering
  • Familiarity with back-end development and Postgres databases
  • Experience with modern front-end development (TypeScript / React)
  • Excellent written communication - clear, structured, and precise

Nice to haves

  • Publications at leading ML venues (e.g. NeurIPS, ICLR, ICML) or related research areas
  • Familiarity with common LLM evaluation tooling (e.g. OpenAI Evals or similar frameworks)
