1. Platform Architecture & Development :

- Own the core React Native application architecture, ensuring optimal state management, module organization, and code reusability across iOS and Android.

- Drive the adoption of best practices, new libraries, and updates within the React Native ecosystem to keep the platform modern and secure.

- Focus on performance tuning, memory management, and reducing app size to ensure a flawless user experience.

2. DevOps, Tooling, & CI/CD :

- Serve as the Subject Matter Expert (SME) for all mobile-related security, performance, and operational issues.

Required Skills and Qualifications :

- 5 years of professional experience in mobile application development.

- 3 years of deep, hands-on experience as a React Native Developer, focusing on architecture and tooling rather than just feature development.

2. Android : Experience with Kotlin/Java for writing native modules and understanding the Android build system (Gradle).

- Proven experience implementing and maintaining CI/CD pipelines for mobile applications.
