  • Deep practical understanding of how LLMs reason, how to structure inputs, and how to measure improvement.

Benefits

  • Unlimited Learning Stipend: books, courses, or conferences of your choice.
  • Comprehensive Health, Dental, and Vision coverage.
  • 401(k) via Human Interest.
  • Relocation assistance to San Francisco (if applicable).
