Sponsors, but it's cap-subject — you still face the weighted lottery (~61% per draw at Level IV). Good if you win; have a cap-exempt backup on your list.

About the role
- You'll work directly with me and a very small engineering team.
Responsibilities
- Build reliable browser authentication and session isolation.
- Design retries, replay, cancellation, recovery, and observability.
Skills
- What we're building
- It takes weeks.
- CharacterQuilt uses computer-use agents to do that work inside the software companies already use.
- A campaign that took three months can now ship in two days.
- You'll own the runtime behind every agent run:
- workers, sandboxes, files, skills, authenticated browsers, durable state, retries, recovery, and the API and CLI around the system.
- Our agents touch customer software and real budgets, so "probably worked" is not good enough.
Compensation
- $250k-$350k
Benefits
- Five days a week in Union Square. $250K to $350K base plus 0.5% to 3% equity.
Company info
- Ship the API, CLI, and MCP surfaces customers and our own agents use.
Visa & Work Authorization
- We do not sponsor US visas
