  • Develop and maintain backend systems including API services, databases, and server-side logic
  • Optimize tech stack and applications for maximum precision and speed
  • Write clean, efficient, and well-documented code, following industry best practices—the Falconer platform will help you!

  • Skilled at prompt engineering
  • Ability to implement backend systems in Python and/or Node.js
  • You can evaluate tradeoffs and propose the most appropriate storage solution (SQL, NoSQL, Vector DBs, Graph databases)
  • You enjoy hard problems and open-ended assignments
  • You use data to make decisions, and experiment your way around hard problems

Bonus points:

  • You've developed products with LLMs before (extra if you've already built your own agents)
  • You have fine-tuned foundational models to tailor responses to specific data use cases
  • You have experience with LlamaIndex and Memgraph to produce knowledge graphs

Perks and benefits:

  • Generous equity package
  • Competitive salary and benefits
  • 401(k) retirement account
  • The best equipment and tools, like a spec'd out MacBook, and dev prod tools like Cursor, Claude, and Linear to help you move fast
  • Flexible work arrangements with in-office work or hybrid work for the right candidate
  • Our current office is in San Francisco, just steps from Caltrain
