Requirements
- Proven track record of independently delivering substantial full-stack product features, with significant frontend engineering expertise.
- Deep proficiency in React, TypeScript, HTML, and CSS, including component design, complex state management, asynchronous operations, and performance optimization.
- Experience shipping rich, interactive products like editors, workflow builders, developer tools, or complex data applications.
- Strong product and interaction judgment, with the ability to simplify technical workflows.
- Practical knowledge of accessibility, including semantic interfaces, keyboard navigation, focus management, and accessible component behavior.
- Demonstrated ability to independently ship backend changes, including data models, APIs, services, and background jobs.
- Experience with Rails or a comparable framework; Rails experience is preferred.
- Pragmatic judgment for improving existing codebases, knowing when to reuse, refactor, or introduce new abstractions.

- Ownership of production outcomes and curiosity about AI agents, execution traces, and human review workflows.
