• 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
