Senior React Native Engineer

Senior React Native Engineer

Engineering  ·  Dubai, UAE  ·  Full-time

Millions of people across the GCC touch the screens you’ll build. Justlife’s app is how households in six countries run their homes — over 15 million sessions and counting — and on mobile, polish and performance aren’t a nice-to-have, they’re the product.

We’re the region’s leading super-app for home services, scaling fast across the UAE and KSA, and we’re building an AI-first engineering organization. We’re looking for a Senior React Native Engineer who cares deeply about craft, wants to own a major part of our mobile experience, and helps define how an AI-first mobile team builds — not just inherits it.

What you’ll own

As a Senior React Native Engineer, you’ll take end-to-end ownership of a major surface of our mobile platform — setting mobile architecture direction, driving release quality, and mentoring the engineers around you. You’ll work shoulder-to-shoulder with product managers, UI & UX designers, and operations to ship experiences customers love. Some of what you’ll work on:

• Consumer experience: the consumer app millions of customers use to book and manage home services across 10 cities.
• Performance & craft: Profile, debug, and optimize React Native experiences to keep the app smooth, responsive, and reliable at scale.
• Architecture: Help define scalable mobile architecture, improve code quality, integrate native modules, and keep the codebase clean, maintainable, and future-ready.
• Experimentation & AI: Support A/B experiments, rapid prototyping, and the use of AI tools to improve development speed, quality, and decision-making.
• Quality & releases: Contribute to a strong testing and release pipeline using tools such as Maestro, CI/CD, automated checks, and production monitoring.

What we’re looking for (must-have)

• Strong hands-on experience with React Native, TypeScript, and modern mobile development practices.
• Solid native understanding of both iOS and Android, including enough Swift/Objective-C and Kotlin/Java to debug, profile, and integrate native modules.
• Proven experience improving mobile app performance, stability, and user experience.
• Strong understanding of clean code, SOLID principles, scalable architecture, and maintainable component design.
• Senior-level ownership: you can take a feature from design to production, make architecture trade-offs, communicate clearly, and mentor other engineers.

Nice to have

• Experience working on apps used across multiple countries, languages, currencies, or market-specific flows.
• Experience with mobile CI/CD pipelines, release automation, App Store / Play Store release processes, and production monitoring.
• Experience building for multiple markets or localizing apps at scale.
