Design, build, and maintain high-quality mobile applications for iOS and Android, both natively (Swift / Kotlin) and in React Native, choosing the right layer for each feature.

Own end-to-end release management: code signing, provisioning, build pipelines, App Store Connect and Google Play Console submissions, phased rollouts, review-rejection handling, and release notes.

Implement and operate React Native over-the-air (OTA) update pipelines (e.g., Expo Updates / EAS Update, CodePush or equivalent), including channel strategy, rollback, and version-gating.

Integrate and manage Firebase services — Authentication, Cloud Firestore / Realtime Database, Cloud Messaging (push), Crashlytics, Remote Config, Analytics, and App Distribution.

Build robust networking layers: RESTful POST/GET API integration, request batching, retry/backoff, and real-time communication via WebSockets or Server-Sent Events (SSE).

Implement bulk upload capabilities for large media and data sets — chunked/resumable uploads, background transfer, queueing, progress tracking, and failure recovery under poor connectivity.

Lead mobile security audits: secure storage (Keychain / Keystore), certificate pinning, obfuscation, secrets handling, OWASP MASVS alignment, dependency vulnerability scanning, and remediation of findings from internal or third-party penetration tests.

Design, develop, and ship Unity-based VR applications (Meta Quest / OpenXR), including interaction and spatial UI design, performance optimisation for standalone headsets, and end-to-end store submission and updates.

Write clean, testable code with unit, integration, and UI tests; participate in code reviews and set mobile and XR engineering standards.

Monitor app health (crash rates, performance, ANRs, battery, network usage, VR frame-rate stability) and drive continuous improvement.

Collaborate closely with backend, product, design, and QA teams; translate product requirements into technical designs and estimates.

Ensure apps comply with platform policies and regional data-protection requirements (e.g., UAE PDPL), including consent flows and privacy manifests.

Required Qualifications

5+ years of professional mobile development experience, with shipped apps on both the App Store and Google Play.

Strong native proficiency in Swift/SwiftUI (iOS) and Kotlin/Jetpack Compose (Android) , including platform lifecycle, permissions, background processing, and native module development.

3+ years of production React Native experience, including native bridging/Turbo

Hands-on Unity (C#) development for VR applications, with at least one VR app shipped to a store (Meta Quest Store / App Lab, SteamVR, or Pico Store). Solid understanding of XR Interaction Toolkit / OpenXR, 6DoF tracking, hand and controller input, spatial UI, and comfort/locomotion best practices, plus experience profiling and optimising for standalone headsets (frame-rate budgets, draw calls, occlusion, foveated rendering).

Modules, navigation, state management, and performance tuning.

Proven ownership of store deployments and release pipelines (Fastlane, Xcode Cloud, Gradle, CI/CD such as GitHub Actions or Bitrise).

Hands-on experience implementing React Native OTA updates in production.

Deep experience with Firebase across authentication, database, messaging, and crash reporting.

Solid understanding of REST API design and consumption, including authenticated POST endpoints, multipart uploads, and pagination.

Experience implementing real-time features using WebSockets and/or Server-Sent Events.

Experience building bulk/batch upload flows for large files or datasets, including resumable and background uploads.

Demonstrated experience conducting or remediating mobile security audits.

Candidate must already be based in the UAE and willing for an onsite role in Abu Dhabi.
