About the role:

As a Senior React Native Engineer, you'll play a key role in building and scaling mobile experiences that enable developers and users to interact with Web3 infrastructure effortlessly. You’ll be responsible for shipping high-quality, high-performance apps—with special attention to startup time, interaction smoothness, and codebase maintainability.

You’ll collaborate with a cross-functional team to define, build, and refine features that are fast, intuitive, and robust.

Key responsibilities:

• Architect, design, and implement fast, scalable, and reliable mobile features in React Native.

• Work closely with design to create pixel-perfect, platform-consistent interfaces.

• Lead performance optimization efforts, including rendering performance, app startup, and interaction latency.

• Write clean, testable, and maintainable code that scales with our user base.

• Integrate APIs and manage data across app screens, including caching, loading states, and error handling.

• Debug and fix production issues, track metrics, and help improve the overall reliability of the mobile app.

• Contribute to mobile architecture, development standards, and tooling decisions.

• Document decisions, patterns, and systems for internal and external audiences.

What does success in this role look like?

• In three months, you've become a core contributor, leading critical features with a focus on UX and speed. You're familiar with the codebase, shipping confidently, and offering thoughtful input in architecture discussions.

• In six months, you're driving core mobile projects from idea to execution, improving app speed, polish, and reliability. You’re mentoring others and actively raising the quality bar.

• In twelve months, you're shaping the long-term direction of the mobile platform, championing scalable architecture, and improving app performance at scale.
