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
As our first dedicated Senior Mobile hire, you will bridge the gap between design and engineering. You will:
- Ship to Production: Take full ownership of the lifecycle for both iOS and Android platforms.

- 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).
