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.
• One thing to know
• You’ll join our on-call rota — we keep it fair, shared, and well-supported.
• We care about sustainable pace and craft, not crunch.
