- Translate business requirements, user journeys, and UX designs into reusable, responsive, and pixel-accurate components.
- Develop clean, modular, testable, and maintainable code using JavaScript and TypeScript.
- Integrate mobile applications with RESTful or GraphQL APIs, authentication services, analytics, notifications, and third-party SDKs.
- Implement platform-specific capabilities and native modules using Kotlin/Java for Android and Swift/Objective-C for iOS when required.
- Manage application state, navigation, offline behaviour, caching, error handling, and secure local storage.
- Optimise application start-up time, rendering, memory usage, network performance, animations, and battery consumption.
- Write and maintain unit, component, integration, and end-to-end automated tests.
- Diagnose and resolve functional defects, crashes, performance bottlenecks, and platform-specific issues across devices and operating-system versions.
- Participate in solution design, estimation,



sprint planning, code reviews, technical documentation, and Agile ceremonies.
- Support CI/CD pipelines, environment configuration, code signing, build automation, release management, and deployment to Google Play and the Apple App Store.
- Apply secure-coding, privacy, accessibility, observability, and mobile engineering best practices throughout the development lifecycle.
- Monitor production stability and collaborate with support teams to analyse logs, crashes, and user-impacting incidents.
- Evaluate React Native upgrades, libraries, and architectural changes while managing compatibility and technical debt.

Required Technical Skills

- Robust hands-on experience with React Native, React, JavaScript (ES6+), and TypeScript.
- Sound understanding of React concepts, hooks, component lifecycle, reusable component design, and common mobile architecture patterns.
- Experience with state-management solutions such as Redux Toolkit, Zustand, MobX, or Context API.
- Experience with React Navigation or an equivalent navigation framework.
- Proficiency in integrating RESTful APIs, JSON payloads, asynchronous workflows, and token-based authentication.
- Working knowledge of Android Studio, Gradle, Xcode, CocoaPods or Swift Package Manager, simulators, emulators,



and physical-device debugging.
- Practical exposure to native Android and iOS development, including platform permissions, deep links, push notifications, background processing, and application lifecycle.
- Experience with unit and component testing tools such as Jest and React Native Testing Library, plus an end-to-end testing framework.
- Proficiency with Git, branching strategies, pull requests, code reviews, and CI/CD workflows.
- Understanding of mobile security practices, including secure storage, certificate handling, data protection, input validation, and safe dependency management.
- Experience with crash reporting, analytics, logging, and performance-monitoring tools.
- Strong troubleshooting, analytical, communication, and cross-functional collaboration skills.

Preferred Skills

- Experience with the React Native New Architecture, including Fabric, JSI, Codegen, and Turbo Native Modules.
- Knowledge of Expo, Expo Application Services, over-the-air update strategies, or equivalent tooling.
- Experience developing native modules or platform SDKs using Kotlin/Java and Swift/Objective-C.
- Exposure to accessibility standards, localisation, responsive layouts, and device or tablet form factors.
- Experience with Firebase services, application monitoring, feature flags, remote configuration, or mobile analytics.
- Understanding of mobile DevSecOps, automated quality gates, dependency scanning, and secure release practices.
- Knowledge of Agile/Scrum delivery and experience working in distributed, cross-functional teams.
