  • Optimize for performance, reliability, and smooth UX across devices.
  • Implement push notifications, offline support, and mobile-specific workflows.

What You Bring

  • 4+ years of mobile development experience with strong React Native proficiency.
  • Proven experience publishing and maintaining apps on both App Store and Play Store.
  • Solid understanding of mobile CI/CD, app signing, versioning, and release management.
  • Good eye for mobile UX and performance optimization.

Nice to Have

  • Experience with React and NestJS (our web stack).
  • Familiarity with HRIS or HR-related applications.
  • Experience with background tasks, biometric auth, or deep linking in React Native.
