  • Mobile DevOps Engineer (CI/CD, App Store/Play Store deployment)
  • UI/UX Engineer specialising in Mobile Interfaces

Core Responsibilities

Primary Functions

  1. Design, develop and deploy mobile applications using React Native for both iOS and Android platforms, delivering smooth and scalable user‑experiences.
  2. Collaborate with product, UX/UI and backend teams to translate wireframes, mockups and business requirements into functional mobile features and components.
  3. Write clean, maintainable and reusable code using JavaScript/TypeScript and React Native best practices, ensuring code quality and long‑term maintainability.
  4. Integrate mobile applications with RESTful and/or GraphQL APIs, third‑party SDKs, native modules, push notifications, geolocation and device sensors as required.
  5. Build responsive, pixel‑perfect UI components and animations, ensuring mobile UX is native‑feel and consistent across platforms and device types.
  6. Implement state management solutions (Redux, Context API, MobX) to ensure predictable and efficient mobile application behaviour.
  7. Ensure offline capability, caching, local data persistence, background tasks and synchronization to enable robust mobile usage in variable network conditions.
  8. Debug, diagnose and fix performance bottlenecks, memory leaks, UI freezes and platform‑specific issues to optimise mobile app performance.
  9. Participate in code reviews, maintain version control (Git), support build automation, CI/CD pipelines and app‑store release processes.
  10. Publish and maintain applications in Apple App Store and Google Play Store, manage releases, rollbacks, beta testing and monitor store metrics.
  11. Stay current with mobile development trends, new React Native ecosystem libraries, platform updates (iOS/Android) and incorporate them into roadmap.
  12. Work with QA engineers to implement automated testing (unit, integration, end‑to‑end) and manual testing of mobile app features to ensure reliability.
  13. Ensure mobile applications comply with security best‑practices, accessibility standards and data‑privacy regulations across platforms.
  14. Collaborate in agile development teams, participate in sprint planning, backlog refinement, daily stand‑ups and retrospective sessions.
  15. Mentor junior mobile developers, share code patterns, libraries, best practices and elevate team productivity and code quality.
  16. Refactor legacy mobile codebases or native components to modern React Native stacks, improve maintainability and reuse across platforms.
  17. Monitor analytics, crash reports, performance KPIs and user‑feedback metrics; implement changes to enhance user‑engagement and retention.
  18. Liaise with infrastructure and DevOps teams to ensure efficient mobile build and deployment pipelines (Fastlane, GitHub Actions, Bitrise, Expo) and environment management.
  19. Plan and estimate mobile deliverables, assess technical risks, propose mitigation strategies and deliver features on time and within budget.
  20. Contribute to mobile architecture decisions (module separation, native bridges, code sharing), enforce mobile coding standards and continuous improvement.

Secondary Functions

  • Support ad‑hoc mobile feature requests, prototypes or proof‑of‑concepts to validate new ideas.
  • Contribute to the mobile product roadmap and strategy by recommending technologies, libraries and frameworks for future scalability.
  • Collaborate with business units to convert user and process needs into engineering tasks, mobile user‑stories and backlog items.
  • Participate actively in mobile team agile ceremonies, provide retrospective feedback and drive sprint deliveries.
