- Strong communication skills and a bias toward action

- Background at a strong company, a top university, or a track record of independent technical projects

Nice to Have

- Exposure to human-in-the-loop or agentic data systems

This is a six-day-a-week, in-person founding role for someone who wants outsized ownership and is energized by startup intensity.
