• Collaborate closely with designers, product managers, and backend engineers to create seamless user experiences.
• Integrate APIs and blockchain data efficiently to deliver responsive, high-performance apps.
• Optimize app performance and memory utilization while maintaining security best practices.
• Review and improve application performance, reliability, and scalability.
• Contribute to code reviews, mentoring, and improving engineering standards.
• Stay up-to-date with React Native and mobile development best practices.

You Should Have

• 5+ years of professional experience developing mobile applications.
• 3+ years of experience with React Native in production environments.
• A proven track record of building and launching 0 → 1 mobile apps, ideally in consumer or fintech domains.
• Experience shipping and independently launching commercial mobile apps from 0 → 1, including handling App Store and Play Store submissions, understanding review nuances, and optimizing for deployment success—with examples available to share.
• Deep understanding of mobile development fundamentals, performance optimization, and modern UI/UX design principles.
• Strong familiarity with native device capabilities—including storage, encryption, memory utilization, background tasks, and permission handling.
• Proficiency with TypeScript, React Hooks, Redux (or similar state management libraries).
• Experience with integrating APIs, analytics, and third-party SDKs.
• Strong debugging and self-sufficient problem-solving skills.
• You leverage AI tools to enhance your workflow, while maintaining strong engineering fundamentals and code craftsmanship.

Bonus Points

• Familiarity with Web3, wallets, or blockchain-based applications.
• Experience with LLMs, on-device browsers, or chat applications.
• Experience with native iOS (Swift) or Android (Kotlin/Java) development.
• Understanding of mobile app security and encryption principles.
