  • Collaborate closely with product and design to align on goals and ship with confidence
  • Talk with users and use the product yourself to understand real-world needs and opportunities
  • Push through obstacles with resourcefulness and a strong problem-solving mindset
  • Learn new concepts quickly and apply them to real production challenges
  • Stay up to date on the latest in AI research and engineering
  • Take on tasks that stretch your abilities and work hard to close skill gaps quickly
  • Contribute to a culture of ownership, ambition, and fast-paced learning

Requirements

  • A strong technical foundation from a top CS program or equivalent hands-on experience building real systems
  • Evidence of ambitious, self-driven projects or internships that required problem solving and ownership
  • Solid programming fundamentals and comfort with TypeScript
  • Exceptional ability to read deeply, reason clearly, and communicate complex ideas
  • Curiosity about AI systems and a desire to push beyond easy or obvious solutions
  • A personal track record of learning quickly and putting in real effort to master difficult skills
  • Experience working in fast-paced environments while balancing care with urgency.

Nice to have

  • Prior internships in AI, backend, or infrastructure engineering
  • Previously been one of the first 10 hires at startup
  • Personal projects that show initiative, creativity, and independent thinking
  • Backgrounds or interests that span technical and non-technical domains (e.g. writing, design, philosophy, economics, etc)
