Key Responsibilities:

• Provide technical leadership and oversee the daily mobile engineering operations.
• Define and drive the mobile architecture strategy aligned with business goals.
• Lead the design and development of scalable, high-performance mobile applications using React Native and Type Script.
• Architect modular, reusable component systems and scalable state management solutions (Redux, Zustand, Context API, etc.).
• Design clean navigation, deep linking, and mobile routing strategies (React Navigation, Expo Router).
• Implement secure authentication flows (OAuth/OIDC, biometrics, secure storage, token lifecycle management).
• Drive native module integrations (Swift, Kotlin) for SDKs such as payments, fraud detection, analytics, push notifications, and device security.
• Optimize mobile performance (startup time, bundle size, memory usage, rendering performance, offline caching).
• Establish CI/CD pipelines for mobile (Fastlane, EAS Build, App Store Connect, Google Play Console).
• Lead app release management, versioning strategy, and store compliance.
• Ensure adherence to mobile security best practices, privacy compliance, and accessibility standards.
• Partner with backend teams to define API contracts and optimize mobile-backend interactions.

• 6+ years of hands-on mobile development experience.
• 4+ years leading React Native applications in production environments.
• Proven experience delivering apps to both Apple App Store and Google Play Store.
• Experience working with cloud-based backends (Azure, AWS, or GCP).
• Strong experience with CI/CD pipelines, automated testing, and Dev Ops best practices.
• Strong hands-on experience building production-grade apps using React Native and Type Script.
• Deep understanding of Expo ecosystem (EAS, OTA updates, build pipelines, native configuration).
• Expertise in mobile architecture patterns (Clean Architecture, MVVM, modular architecture).
• Experience integrating native iOS (Swift) and Android (Kotlin) modules into React Native apps.
• Strong understanding of app lifecycle, memory management, threading, and performance tuning.
• Experience implementing push notifications, deep linking, analytics SDKs, and mobile security frameworks.
• Experience with API integrations (REST, GraphQL) and handling network resiliency/offline-first design.
