About The Role

Key Responsibilities

• **Native app maintenance**
• Immediately take ownership of the existing Swift (iOS) and Kotlin (Android) apps.
• Resolve identified critical security issues: Android keystore rotation, static AES IV, cleartext traffic flag.
• **Launch support**
• Ensure both native apps are stable, tested, and fit for soft launch.
• Coordinate with the backend engineer on API integration and the QA engineer on test coverage.
• **Migration planning**
• Define the React Native migration strategy - phased approach, feature parity checklist, shared component library, testing plan.
• **React Native migration**
• Post-launch, lead the incremental migration of both apps to a single React Native codebase.
• Own the architecture: navigation, state management, native module decisions.
• **Security**
• Champion mobile security best practices: certificate pinning, secure storage, ProGuard obfuscation, root/jailbreak detection.
• Several known issues in the current codebase need addressing.
• **App store management**
• Own the App Store (iOS) and Google Play (Android) submission, review, and release processes.
• **Performance**
• Monitor and improve app performance: image loading, memory management, list rendering, network efficiency.

Must Have

• **React Native**
• 3+ years of production React Native experience.
• You have shipped apps on both iOS and Android from a single RN codebase.
• **iOS (Swift)**
• sufficient native iOS experience to read, maintain, and fix the existing Swift codebase through the transition period.
• You do not need to be a Swift specialist, but you cannot be blocked by it.
• **Android (Kotlin)**
• same as above — maintenance-level Kotlin competence.
• The Android app has specific critical security fixes that require native code changes.
• **Mobile security**
• you understand code signing, certificate management, secure storage, and the OWASP Mobile Top 10.
• Several critical vulnerabilities in our apps need fixing immediately.
• **App store processes**
• you have submitted to both App Store and Google Play and understand review guidelines, provisioning profiles, and release management.
• **State management**
• Redux, Zustand, or equivalent — you have an opinion and can defend it.
• **TypeScript**
• React Native with TypeScript is the target stack.
• Nice to Have:
• **Expo**
• familiarity with the Expo ecosystem and when to use managed vs bare workflow.
• **Native modules**
• experience bridging native iOS/Android functionality into React Native.
• **UAE / Dubai apps**
• awareness of App Store / Play Store requirements for UAE-distributed apps.
• **Real estate or marketplace apps**
• experience with property listings, search, and similar data-rich interfaces.
• **Firebase**
• push notifications via FCM are core to the platform.

Interview Process

• **Stage 1**
• Portfolio review — show us apps you have shipped.
• Walk us through one React Native codebase you are proud of.
• **Stage 2**
• Take-home paid task (2-3 hours) — build a small React Native screen against a mock API.
• We care about structure, not pixel perfection.
• **Stage 3**
• Final conversation with CEO — team fit, transition plan discussion, compensation.
