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.
