Senior React Native Engineer (6+ Month Engagement)

We're hiring a senior software engineer with deep React Native expertise to lead development on an ongoing mobile product. This is a fixed-price engagement with scope for 6+ months of continued work as milestones are completed.

⚠️ US-based applicants only. Proposals from outside the United States will not be reviewed. You must be able to verify US residency and work during US business hours.

About the Role
You'll own significant portions of our React Native codebase, ship production features to both iOS and Android, and help shape technical direction on the mobile side. This isn't a junior-friendly role - we need someone who can architect, execute, and deploy without hand-holding.


What You'll Do
- Design and build features in React Native with TypeScript across iOS and Android
- Drop into native Swift (iOS) or Kotlin (Android) when bridging, debugging, or optimizing performance requires it
- Architect and maintain state management using Redux (or justify a better choice)
- Own App Store and Google Play submissions end-to-end, including provisioning, signing, review responses, and phased rollouts
- Collaborate with backend and design on API contracts and UX decisions
- Write clean, tested, maintainable code and review others' work

Must-Have Qualifications

- 5+ years of professional software engineering experience, with 3+ years focused on React Native in production
- Strong TypeScript fluency — not "I've used it," but genuinely comfortable with advanced types, generics, and strict mode
- Hands-on native iOS development in Swift (writing, not just reading)
- Hands-on native Android development in Kotlin (writing, not just reading)
- Production experience with Redux or a comparable state management library (Zustand, MobX, Redux Toolkit, etc.) at scale
- Demonstrated history of shipping apps to the App Store and Google Play, including handling rejections and store review processes
- Based in the United States

Nice to Have

- Experience with CI/CD for mobile (Fastlane, EAS, Bitrise)
- Familiarity with native module authoring and React Native's New Architecture (Fabric/TurboModules)
- Performance profiling experience on mobile
