The Role
We are seeking a seasoned, autonomous Senior Mobile App Developer (React Native & TypeScript) to design, build, and ship a cross-platform mobile application (iOS & Android) completely from scratch.
You will take full ownership of the end-to-end mobile lifecycle, from initial architecture to App Store/Google Play store submissions and post-launch analytics.
Key Responsibilities
- End-to-End Development: Design, build, and ship a high-performance cross-platform mobile app (iOS + Android) from scratch using React Native, Expo, and TypeScript.
- Backend & API Collaboration: Work closely with the backend engineering team to shape REST/GraphQL API contracts, handling secure authentication, data sync, and background jobs.
- Feature Engineering: Implement deep linking, push notifications (FCM/APNs), user account management, and in-app payments (Apple Pay / Google Pay).
- Media & Interactive Features: Build rich, interactive, media-heavy features including image handling, mobile editors, and real-time data updates.
- Release & Store Management: Fully own the app release process, including versioning, signing, provisioning, Fastlane/EAS Build pipelines, and navigating App Store & Google Play review compliance.
- Performance & Monitoring: Implement mobile analytics, monitor crash reports, optimize app size, and maintain Core Web Vitals/mobile runtime performance.
Requirements
- Experience: 3+ years of professional mobile app development experience with proven production deployments (not just hobby projects).
- Tech Stack Mastery: Deep, production-level expertise in React Native (ideally with Expo) and TypeScript.
- Live App Portfolio: Must have personally built and shipped live apps currently available on the Apple App Store and Google Play Store (Live store links required during application).
- API & State Management: Strong experience with REST/GraphQL API integration, complex state management, offline data handling, and local storage.
- Mobile Infrastructure: Proven hands-on experience with Push Notifications (FCM/APNs), Deep Linking, and Native Build Tooling (Xcode, Android Studio).
- Payments & CI/CD: Practical experience integrating In-App Purchases / Apple Pay / Google Pay, and setting up CI/CD workflows (EAS Build, Fastlane, or App Center).
- Language & Soft Skills: Professional working proficiency in English (both written and spoken). Comfortable making independent architectural decisions in a remote team setting.
Benefits
- Competitive salary package based on experience.
- 100% Remote working flexibility from anywhere.
- Opportunity to architect a modern mobile platform completely from scratch.
- Collaborative, engineering-first culture with direct international exposure.
