• Drive accessibility improvements across the board - keyboard navigation, ARIA compliance, mobile interactions.
• Own governance and standards: reduce redundancy, enforce consistency, and make sure product teams are building with the system, not around it.

• You're fluent in React and TypeScript, and have solid knowledge of web components and advanced CSS (you know the difference between vh and dvh and why it matters).

• You follow the design systems space closely and have opinions: who's leading, what's overrated, what's next.

• You're excited about how LLMs and agents change the way we think about component architecture and developer tooling.

• Bonus: React Native experience, or appetite to learn.
