Full job description

Location: Remote (Company in Mumbai)

Company: Big Rattle Technologies Private Limited

Immediate Joiners only.

We're looking for a seasoned React Native developer who has shipped production-grade mobile apps on both iOS and Android — ideally in the high-traffic, high-stakes world of e-commerce. You'll own the mobile experience end-to-end: architecture, performance, and flawless UX across devices.

Key Responsibilities:

Design and build scalable React Native apps for both iOS and Android from scratch to App Store / Play Store deployment.
Architect complex e-commerce flows — product catalogues, cart, checkout, payment gateway integration, and order tracking.
Optimize app performance: reduce TTI, maintain smooth 60fps animations, and manage memory on low-end devices.
Integrate REST and GraphQL APIs; manage state with Redux Toolkit, Zustand, or React Query.
Implement push notifications, deep linking, in-app navigation, and offline-first strategies.
Write clean, well-tested code; maintain CI/CD pipelines using Fastlane, GitHub Actions, or Bitrise.
Collaborate with designers, backend engineers, and product managers in Agile sprints.
Conduct code reviews and mentor junior mobile developers.

Core Mobile :
- React Native CLI & Expo
- TypeScript
- React Navigation v6+
- iOS (Swift basics) & Android (Kotlin basics)
- Xcode & Android Studio
E-commerce & Integrations:
- Product / Cart / Checkout flows
- Razorpay, Stripe, PayPal SDKs
- Wishlist, search UX, filters
- Order tracking & delivery status
- Push notifications & deep linking
State & Data:
- Redux Toolkit / Zustand
- React Query / SWR
- REST & GraphQL APIs
- AsyncStorage / MMKV
- Firebase Realtime DB / Firestore
DevOps & Tooling:
- Fastlane & GitHub Actions / Bitrise
- Jest (unit) & Detox (E2E)
- Firebase Crashlytics & Sentry
- Flipper / Reactotron
- App Store & Play Store deployments

Nice to Have skills:

New Architecture · RN Web · AR try-on · RTL support · Shopify SDK · WCAG · Maps SDK

React Native New Architecture (JSI / Fabric / TurboModules)
React Native Web or monorepo setups (Nx, Turborepo)
AR product try-on experiences (ARKit / ARCore)
Shopify Storefront API or WooCommerce SDK experience
Accessibility (WCAG mobile) implementation
Live order-tracking maps (Google Maps / Mapbox)

Required Qualifications:

Bachelor’s degree in computer science, Engineering, or related field OR equivalent practical experience.
