- A demonstrated track record of building, such as personal projects or public code you have shipped.
- High agency, fast learning and clear, concise communication about what you built and why.
- Strong builder mindset and motivation to create things rather than to add lines to a resume.
- Willingness to work in person five days a week in San Francisco.
