About the role

Eigen is looking for outlier AI Platform Engineers to help build the future of human connection. You must have experience designing large yet maintainable AI systems, and be excited to do so about 3 times faster than most people think is possible.

We are well-capitalized and backed by Peter Fenton (Benchmark), David Singleton (ex CTO, Stripe), Gustav Söderström (CEO, Spotify), and only hire the best. Expect talented, thoughtful colleagues and a work environment that’ll expect you to do your best work every day.

What you'll do

  • Invent the technological paradigms that’ll govern the next generation of products in the age of consumer AI
  • Advance the next big frontier of AI: emotional intelligence and relational reasoning
  • Contribute to our agent harness, high velocity data pipelines, simulations and evals suite, and foundational platform engineering

What we like to see

  • Excited to solve difficult and ambiguous technical problems with a high degree of autonomy
  • Exceptional systems designers that think in terms of architecture, not syntax
  • Founder mentality with attention to detail that care about the backside of the fence
  • Strong communicator with high confidence and low ego
  • P99 consumer of claude code and codex tokens
  • Experience with Typescript, Python, and building agentic systems
