📋 Description

• About us: Syndica supplies the most critical applications in Web3 with enterprise-grade RPC infrastructure and developer tools tailored for the Solana ecosystem. Joining our team means you'll be held to a high standard, technically challenged, and grow close to a group of individuals passionate about building new infrastructure technologies. • About you: You're a seasoned mobile engineer who thrives in a fast-paced, collaborative environment and loves crafting exceptional user experiences. • Standout Experience: 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. • 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. • 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.
