• Participating in on-call rotation and contributing to incident response

Ideal Profile:

• 5+ years of professional software engineering experience, including shipping production React Native applications

• Deep proficiency in React, React Native, JavaScript, and TypeScript

• Strong understanding of React Native architecture, including component design, rendering, state management, and the bridge/JSI/native layers
