Software Dev Engineer II

Key Responsibilities Develop and maintain React Native applications for iOS and Android, ensuring optimal performance and responsiveness. Implement app performance optimizations (reducing app size, improving load times, and memory management). Debug, troubleshoot, and improve application stability. Write unit and integration tests using React Native/React Testing Library to ensure app reliability. Collaborate with designers, product managers, and backend engineers to deliver seamless user experiences. Integrate APIs, third-party SDKs, and state management solutions like Redux, Zustand, Recoil, or Context API. Ensure best practices in code architecture, security, and scalability. Lead adoption of AI-assisted development tools (Claude, GitHub Copilot, etc.) within the team — evaluate effectiveness, establish best practices, and mentor others on productivity gains What we are looking for Core Technical Skills Expert proficiency in React and TypeScript — strong understanding of hooks, state management patterns, and TypeScript best practices Expert proficient in RN and understanding of Native modules.
