- A product mindset — you care deeply about UX, edge cases, and performance.

- You're adept at identifying optimization bottlenecks, and debuggers and code profiling tools are an important part of your toolkit.
- Strong communication skills and comfort working in a collaborative, async environment.

## Bonus points if you've:
