React Native Mobile Engineer (Proptech)

Location: On Site (Dubai) Tech Stack: Swift (iOS) / Kotlin (Android) — migrating to React Native Salary: AED 15,000 + performance-based bonus About the Role OWNRSCLB currently has separate native iOS (Swift) and Android (Kotlin) apps.

Our strategic decision is to consolidate onto a single React Native codebase - one team, one product, both platforms. We are looking for a React Native engineer who can maintain and stabilise the existing native apps through launch, then lead the migration to React Native over the following 6-12 months.

You will be the sole mobile engineer on the team, which means real ownership and real impact. This is not a role for someone who needs close supervision. You will be trusted to make the right mobile decisions, flag risks early, and deliver quality product on two platforms simultaneously during the transition period.

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.
