Senior React Native Engineer (Hands-on Programmer)
Location: Riyadh, Riyadh Province, Saudi Arabia
Department: Information Technology (IT)
Workplace: on_site
Employment Type: full
Description
We are looking for a low-level, high-output React Native Programmer. This is a role for an engineer who understands what’s happening under the hood—beyond just rendering components. You will be responsible for the technical architecture, performance optimization, and end-to-end delivery of complex mobile systems in our Riyadh office.
Requirements
Core Technical Requirements
- Deep React Native Internals: Expert-level knowledge of the React Native lifecycle, the Bridge, JSI, and the New Architecture (Turbo Modules/Fabric).
- JavaScript & TypeScript: Mastery of ES6+, asynchronous programming patterns, and strict type safety.
- State & Data: Advanced implementation of state management (Redux + Saga/Thunk, Zustand, or TanStack Query) and efficient data caching strategies.
- Native Bridging: Proven ability to write Native Modules and navigate the communication between JS and Swift/Objective-C (iOS) or Kotlin/Java (Android).
- Performance Engineering: Experience with memory leak detection, CPU profiling using Flipper or Xcode Instruments, and optimizing app startup time (Hermes/re-renders).
- Cross-Platform Versatility: Strong plus if you have hands-on experience with Flutter (Dart) or have transitioned apps between frameworks.
- Git understating and version control
Engineering Responsibilities
- Architect scalable front-end logic for complex, high-traffic mobile applications.
- Integrate deeply with RESTful APIs, WebSockets, and third-party SDKs.
- Manage the full release cycle, including CodePush deployments and App Store/Play Store submission hurdles.
- Troubleshoot "hard-to-repro" bugs that require digging into native code or node_modules.
- Ensure UI fidelity through high-performance animations (Reanimated 3, Moti).
