Syndica is seeking a Senior React Native Engineer to build and scale mobile experiences that enable developers and users to interact seamlessly with Web3 infrastructure. You will be responsible for shipping high-quality, high-performance applications, with special attention to startup time, interaction smoothness, and codebase maintainability.
What You'll Do
- 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 We're Looking For
- 5+ years of mobile development experience with production apps at scale.
- Deep experience with React Native.
- Proficiency with the nuances of native iOS development.
- Built or maintained apps in production with a high volume of users.
- Solid understanding of mobile architecture, component design, and performance optimization.
- Experience managing data flow, asynchronous logic, and API integrations (e.g., REST, GraphQL, caching).
- A track record of shipping quickly while maintaining a high bar for code quality and product polish.
- Excellent communication skills and comfort working across engineering, design, and product.
- A Bachelor’s degree in Computer Science or equivalent practical experience.
Nice to Have
- Experience building offline-first features or persistent app state with tools like AsyncStorage or SQLite.
- Worked at developer-tooling companies or mobile-first teams (e.g., Stripe, Coinbase, Robinhood).
- Experience with Web3 integrations (e.g., Solana wallets, secure transactions, or dApp connectivity).
- Led large mobile initiatives, greenfield app builds, or major performance refactors.
Technical Stack
- React Native
- iOS
- REST
- GraphQL
- AsyncStorage
- SQLite
You'll be held to a high standard, technically challenged, and grow close to a group of individuals passionate about building new infrastructure technologies.
