ABOUT THE ROLE:
Rupeestop is a fintech platform helping people take control of their financial future. We're looking for a
React Native Developer who is sharp, hands-on, and genuinely excited about building great mobile
products. You'll work closely with product, design, and backend teams to ship polished, high-performing
apps — and own your work end to end.
We move fast, experiment often, and iterate relentlessly. You'll be expected to take full ownership, grow into
a leadership role, and bring thinking that goes beyond your assigned tasks. If you get restless when things
are too predictable — you'll fit right in.
WHAT YOU'LL DO:
- Build and maintain production-quality mobile apps for Android and iOS using React Native.
- Own features end-to-end — from design handoff through deployment on Play Store and App Store.
- Integrate REST APIs, authentication flows, push notifications, deep linking, and real-time features.
- Optimise app performance, memory usage, animations, and stability across a range of devices.
- Debug, test, and iterate — improving reliability and quality continuously.
- Use AI-assisted development tools (Cursor, Copilot, etc.) to move faster and build smarter.
- Contribute to architecture decisions and participate actively in product and team discussions.
WHAT YOU NEED:
- Strong hands-on React Native experience — including at least one app live on Play Store or App
Store.
- Solid JavaScript / TypeScript skills; comfort with modern patterns and ES standards.
- Experience with React Native CLI and native module bridging — not just Expo.
- Familiarity with state management (Redux, Zustand) and navigation (React Navigation).
- Understanding of app signing, build configs, and deployment workflows (Fastlane, EAS, etc.).
- Experience with Firebase, push notifications, background tasks, and device-level permissions.
- Ability to read or write basic native code (Kotlin/Java or Swift/Obj-C) is a strong plus.
- Comfortable with Git, pull request workflows, and working in a shared codebase.
GOOD TO HAVE:
- CI/CD experience for mobile builds (Bitrise, GitHub Actions, Fastlane).
- Knowledge of WebSockets, offline-first architecture, or real-time data sync.
- Prior experience in fintech, consumer apps, or high-traffic mobile products.
- Consistent use of AI tools as part of your daily development workflow.
WHO YOU ARE:
- You take full ownership — you don't wait to be told, you see what needs doing and do it.
- Detail-obsessed: broken UI, inconsistent spacing, and edge cases bother you.
- A natural experimenter — comfortable trying new approaches, breaking things, and fixing them.
- Adaptable: priorities shift in a startup environment, and you handle that well.
- Ready to step into a team lead role as we scale — mentor others, make decisions, drive quality.
