Required

3+ years of experience

Immense pride in the work you do and a desire to build the best products on earth

Builders with taste: You know the difference between good and great, and you can't sleep until you've achieved the latter

Systems thinkers: You see patterns others miss, and you understand how AI fits into larger systems. You design for reliability, not just capability

Relentless learners: You dive into unfamiliar domains and emerge with either expertise or a delusional drive to acquire it, and you form hypotheses, run experiments, and let data guide your decisions

Clear communicators: Complex model behaviors become understandable when you explain them

Domain experts: Deep experience with LLMs, prompt engineering, fine-tuning, or AI infrastructure. You've shipped AI systems that real users depend on
