About Us
We are a Dubai-based technology company that designs and builds mobile applications across several categories
- business applications, news applications and social media applications
- for users across the GCC. We work with an automation-first, security-first, quality-first mindset and are growing a senior mobile team.

About the Role
We are looking for one engineer who can own the real-time side of our products on both iOS and Android: instant messaging and chat, live feeds and breaking-news updates, presence, notifications and in-app communication that must feel instant and never lose data. You can work natively on both platforms, or with a cross-platform stack backed by strong native skills. You will set the mobile real-time architecture, build the core once and make it feel native on each platform.

Responsibilities:

Own the mobile architecture for iOS and Android, including the shared real-time core used across our business, news and social apps. Build the connection layer (WebSocket / XMPP): reconnect, message ordering, delivery and read receipts, presence, typing and live feed updates. Deliver offline-first storage and sync on both platforms. Implement notifications and calls: APNs / PushKit / CallKit on iOS; FCM / WorkManager / ConnectionService on Android. Write native platform code where cross-platform falls short (background tasks, notification extensions, audio / video). Drive performance, stability and security (E2EE support, secure storage) to production-scale standards. Ship to both stores, run CI/CD, mentor developers and review code.

Requirements:

6+ years of mobile development, with production apps shipped on both the App Store and Google Play. Proven depth in native iOS (Swift) and native Android (Kotlin); or senior Flutter / React Native / Kotlin Multiplatform with hands-on native modules on both platforms. Hands-on experience building real-time features: an instant messaging / chat app is strongly preferred; live feeds, social or live-update apps also considered. Working knowledge of XMPP or an equivalent real-time protocol (WebSocket, MQTT). Strong background in offline-first data, push notifications and background execution on both platforms.
Nice to Have:
Understanding of Erlang-based messaging servers (ejabberd / MongooseIM)
- no Erlang coding required. End-to-end encryption (Signal protocol), WebRTC calls. Experience with news or social media apps; Arabic / RTL UI; Flutter.

What We Offer

Competitive package based on experience, plus UAE employment visa. Ownership of the real-time layer across multiple live products, with a senior team.
