At MECCA, we’re reimagining how beauty and technology meet - and mobile is at the heart of this transformation. As a Senior Mobile Developer, you’ll play a pivotal role in delivering seamless, scalable, and delightful mobile experiences for our customers. You’ll bring deep technical expertise in React Native development, along with a passion for continuous improvement, experimentation, and collaboration. This is more than just building features - you’ll help shape our mobile platform, optimize performance, and champion engineering quality while working closely with other mobile developers, product managers, designers, and backend teams.
We’re looking for someone who thrives on complexity, embraces modern engineering practices, and never stops learning. Whether you’re profiling app performance, experimenting with new tools, or mentoring peers, you’ll be encouraged to innovate, challenge assumptions, and grow in a collaborative, fast-paced environment.
As a Senior Mobile Developer, you will:
- Design, build, and maintain high-performance mobile applications using React Native, with strong knowledge of iOS (Swift) and Android (Kotlin) for bridging and optimisation.
- Ensure applications meet scalability, performance, accessibility, and security best practices.
- Collaborate closely with Product Managers, UX/UI Designers, and QA Engineers to translate ideas into seamless mobile experiences.
- Design and implement seamless integrations with backend systems and cloud services, leveraging REST APIs to deliver reliable, scalable, and performant mobile experiences.
- Apply a test-first mindset, building automated tests (unit, integration, E2E).
- Continuously enhance the CI/CD pipeline, enabling fast, reliable, and low-risk releases.
- Optimise app performance through profiling, debugging, and monitoring tools.
- Implement mobile security measures (OAuth, JWT, biometric authentication) and comply with privacy standards.
- Participate actively in code reviews, architecture discussions, and retrospectives, shaping how we evolve as a team.
- Contribute to a culture of learning and excellence, sharing knowledge, mentoring peers, and staying current with mobile technology trends.
We’re looking for a curious, growth-minded engineer with:
- 5+ years of mobile engineering experience, with strong production experience in React Native.
- Production experience with Expo, including Expo Modules, config plugins, and native app configuration.
- Strong understanding of iOS and Android native development, including Swift, Kotlin, platform APIs, app permissions, push notifications, deep linking, and release workflows.
- Experience building and maintaining shared component libraries or design systems for mobile applications.
- Strong knowledge of mobile UI engineering, including responsive layouts, animations, accessibility, and performance optimisation.
- Practical experience with TanStack Query for server-state management, caching, invalidation, and optimistic updates.
- Experience with Zustand or similar client-state libraries, with a clear understanding of when to separate client state from server state.
- Experience writing automated tests for mobile applications using tools such as Detox, Maestro, Appium, Jest, or React Native Testing Library.
- Strong working knowledge of CI/CD, Git workflows, feature flags, build automation, and continuous delivery for mobile apps.
- Proven experience shipping apps to the App Store and Google Play, including release management, store compliance, staged rollouts, monitoring, crash reporting, and post-release support.
- A strong quality mindset, with experience building secure, resilient, observable, and maintainable mobile applications.
- Clear communication skills, strong technical judgement, and the ability to mentor other engineers.
- Practical fluency with AI-assisted engineering tools, including using AI to accelerate development, testing, debugging, documentation, code review, and technical discovery while maintaining strong engineering standards.
Nice to have:
- Experience working with .NET or C#-based backends and web technologies.
- Exposure to AI/ML concepts or libraries, or interest in experimenting with AI in real products.
- Experience with observability tools (e.g., Datadog, New Relic, or similar).
- Experience working with an e-commerce platform.
- Familiarity with serverless architecture or container-based deployment in AWS.
- Understanding of TDD, QA-as-code, and shift-left testing approaches.
