- Develop and maintain mobile-first design systems in close partnership with product and design teams.
- Integrate mobile apps with backend services and blockchain infrastructure to enable secure wallet functionality and real-time updates.
- Build APIs for mobile clients and implement transaction signing, balance updates, and error recovery logic.
- Drive product quality through testing strategies, continuous delivery practices, and attention to UX detail.
Who You Are
- 5+ years of experience in fullstack and mobile development, with deep expertise in React Native and modern JavaScript frameworks.
- Proficient in TypeScript, with strong experience using Expo and deploying mobile apps to iOS and Android platforms.
- Skilled in state management tools such as Redux, MobX, or Zustand, with a focus on clean architecture and scalability.
- Strong eye for design, with a track record of delivering polished, intuitive mobile user experiences.
- Comfortable working across the stack, with backend experience in Node.js and API integration (REST and GraphQL).
- Experience building real-time features using WebSocket or similar technologies.
- Experience with mobile wallet security, such as biometric authentication, and secure key storage.
- Understanding of mobile-specific blockchain challenges, such as WalletConnect integration and deep linking.
- Experience optimizing React Native apps for performance.
- A high degree of ownership and product intuition, with a focus on quality, performance, and reliability.
