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.
