  • Technical Lead – Mobile DevOps / CI‑CD for Mobile

Core Responsibilities

Primary Functions

  1. Design, develop and maintain mobile applications using React Native for both iOS and Android platforms, ensuring high performance, scalability and maintainability.
  2. Translate wireframes, design mock‑ups and product requirements into high‑quality, reusable component libraries and mobile architecture.
  3. Implement state management solutions (e.g., Redux, MobX, Context API) and integrate with backend APIs (REST, GraphQL) to drive dynamic application behaviour.
  4. Work with native modules and device APIs (e.g., camera, GPS, sensors) when necessary to extend the React Native application beyond standard capabilities.
  5. Optimize application performance: reduce load times, improve responsiveness, handle memory usage, minimize bundle size and work across fragmented device environments.
  6. Collaborate cross‑functionally with UX/UI designers, backend engineers, QA testers, DevOps and product owners to deliver cohesive mobile products on schedule.
  7. Build and maintain CI/CD pipelines for mobile app builds, testing, deployment (App Store / Google Play) and staging environments.
  8. Participate in code reviews, set coding standards, mentor junior developers and encourage best practices such as clean code, automated testing and documentation.
  9. Debug and resolve production issues, fix bugs, manage version control and deliver quick patches while balancing feature development and bug backlog.
  10. Ensure that applications maintain responsive layouts and consistent behaviour across screen sizes, device types, OS versions (iOS, Android) and support localization/internationalization.
  11. Implement and maintain analytics, telemetry and crash‑reporting tools to monitor app health, user behaviour and performance, and utilize data to drive prioritization and feature improvement.
  12. Stay current with evolving React Native, JavaScript/TypeScript, mobile platform features and third‑party libraries; evaluate and integrate new technologies that bring value.
  13. Architect modular, maintainable, testable mobile applications, define folder structure, code modularization, dependency injection and design patterns (e.g., MVVM, Clean Architecture).
  14. Manage mobile app submission workflows: manage App Store / Google Play requirements, versioning, release notes, beta testing, rollout strategies, reviews and governance.
  15. Collaborate with backend services teams to design efficient data fetching, caching, synchronization, offline storage, and error‑handling for mobile clients.
  16. Write and maintain technical documentation: component libraries, API integration guides, testing guides, onboarding materials and mobile architecture diagrams.
  17. Address cross‑platform consistency issues, platform‑specific quirks (iOS/Android), bridging native modules, and manage platform fragmentation.
  18. Engage with mobile device capabilities, sensor integration, connectivity changes, background processing, push notifications and deep linking workflows.
  19. Advocate for user‑experience, accessibility (WCAG / mobile accessibility), responsive interfaces and mobile design best practices, while working closely with designers and QA.
  20. Align mobile feature development with business goals: articulate mobile roadmap, prioritize mobile initiatives, provide feedback on risk/debt, partner with stakeholders, and track key mobile metrics.

Secondary Functions

  • Support ad‑hoc data requests and exploratory mobile analytics (user behaviour, A/B testing, feature usage).
  • Contribute to the organisation’s mobile technology roadmap and cross‑platform strategy.
  • Collaborate with business units (marketing, operations, analytics) to translate mobile requirements into engineering tasks.
  • Participate actively in sprint planning, backlog refinement, stand‑ups, retrospectives and other agile ceremonies within the mobile development team.

Required Skills & Competencies

Hard Skills (Technical)

  • Strong proficiency in JavaScript (ES6+) and TypeScript for mobile application development.
  • In‑depth experience with React Native framework, mobile component lifecycle, performance optimisation and cross‑platform challenges (iOS & Android).
  • Expertise in state management libraries such as Redux, MobX, Context API, and understanding of data flow in mobile apps.
  • Experience integrating with RESTful APIs, GraphQL, third‑party SDKs, offline storage and synchronization mechanisms.
  • Familiarity with native modules development / bridging, Android (Kotlin/Java) and iOS (Swift/Objective‑C) when needed.
  • Strong understanding of mobile UI/UX principles, responsive design, accessibility, and cross‑platform consistency.
  • Experience with mobile build tools and workflows: Xcode, Android Studio, Gradle, CI/CD systems, App Store / Google Play deployment.
  • Proficient in testing frameworks for mobile: unit, integration, end‑to‑end testing (Jest, Detox, Mocha), and code quality practices.
  • Performance profiling and optimisation skills: memory usage, startup time, bundle size, multi‑threading and asynchronous processing.
  • Version control (Git), code review practices, modular architecture, documentation, and mentoring skills.

Soft Skills

  • Excellent communication and collaboration skills: able to articulate mobile technical concepts, work with cross‑functional stakeholders and contribute in agile team contexts.
  • Analytical and problem‑solving mindset: able to debug complex mobile issues, evaluate trade‑offs and implement practical solutions.
  • Ownership and accountability: taking responsibility for mobile application quality, performance, delivery and end‑user experience.
  • Adaptability and continuous learning: stay up to date with rapidly evolving mobile technologies, frameworks, devices and industry trends.
  • Time‑management and prioritisation: manage multiple features, bug fixes, technical debt and releases effectively under deadlines.
  • Mentorship and leadership: support junior developers, enforce coding standards, foster code reviews and drive mobile engineering culture.
  • User‑centric mindset: understand end‑user needs, accessibility, mobile experience, and translate feedback into improvements.
  • Quality‑driven focus: aim for maintainable, testable, high‑performance code rather than quick but shaky releases.
  • Strategic thinking: align mobile development roadmap with product and business objectives, identify risks/debt and propose improvements.
  • Team‑player: collaborate across design, backend, QA and operations to deliver cohesive mobile experiences.
