Navigating the position:
We have a proven concept and a solid foundation, now, we need a seasoned Senior Mobile Engineer to take our React Native proof‑of‑concept and evolve it into a polished, production‑ready application. You won’t just be writing code; you’ll be the architect of our mobile user experience. We are looking for a “Product Engineer”—someone who cares as much about the user experience and the UI storyboard as they do about clean, scalable architecture. You should have deep hands‑on experience shipping commercial apps in both stores (App Store / Google Play), and comfort working in both native and cross‑platform environments.
Key Responsibilities
- Ship to Production: Take full ownership of the lifecycle for both iOS and Android platforms.
- Elevate the Frontend: Use your expert knowledge of React Native and CSS‑in‑JS to build beautiful, responsive, and accessible interfaces.
- Architect for Growth: Introduce best practices, coding standards, and design patterns that will allow us to scale the team and the codebase.
- Automate Everything: Maintain and improve our CI/CD pipelines within Azure DevOps to ensure seamless, automated deployments.
- Collaborate: Work within a loose Agile/Sprint framework, contributing to storyboarding, and regular sprint planning meetings.
- Code Quality: Ensuring high code quality through unit/UI testing, code reviews, and static analysis tools.
Skills, Knowledge and Expertise
You are a senior‑level developer who is "hands‑on" by nature, you don't want to sit in architectural meetings all day; you want to build great products.
- React Native Expert: You have a track record of shipping production‑grade apps and understand the nuances of the bridge, native modules, and performance tuning.
- Design‑Led: You have a keen eye for UX/UI. You understand storyboards and can realise Figma designs into production‑ready components.
- Tooling Savvy: You are comfortable with Azure DevOps, including managing pipelines, boards, and releases.
- Pragmatic Mentor: You enjoy helping others. You’re happy to peer‑review code and set the standard for future junior developers.
- Agile Mindset: You’re comfortable with the iterative nature of a growing product and can thrive in a sprint‑based environment.
Must‑Have Technical Stack
- Experience: Multiple years of commercial experience building and shipping production mobile applications.
- Core: React Native (iOS & Android), TypeScript.
- State & Styling: Your preferred modern styling stack.
- DevOps: Azure DevOps (Pipelines & Boards).
- Testing: Jest, React Native Testing Library.
- Performance: Familiarity with performance profiling tools.
- Security: Implementation of offline support, secure storage (Keychain / Keystore), biometric auth, and encryption.
Valued Technical Stack
- Complexity: Previous work on high‑traffic / consumer‑facing apps or apps with complex business logic.
- Comms: Exposure to REST structured application interfaces, and real‑time features (WebSockets, push notifications, etc).
- Accessibility: Internationalisation, theming, and adaptive layouts.
- Mentoring: Experience mentoring or leading small mobile teams / features.
