Write reusable, well-tested, and maintainable code, taking full ownership across all stages of the mobile software development lifecycle.
Elevate team engineering standards through thorough code reviews, technical mentorship, and active participation in agile planning sessions.

Hands-on experience in building and optimizing React Native architecture (including native modules, Fabric, TurboModules, Hermes, and the New Architecture).
Solid data-fetching and cache-management skills using React Query (v4/v5) to ensure consistent server state across screens.
A forward-thinking mindset and enthusiasm for modern tools, including a practical, open approach to leveraging AI-assisted development tools to boost productivity.
Nice to have:
Strict testing discipline (Jest, React Native Testing Library) as an integrated part of your development workflow.
Hands-on experience with monorepos and internal packages (e.g., Lerna, Nx, npm workspaces).
Experience in FinTech, trading platforms, or high-throughput real-time systems.
We offer*:
