#### What you’ll do

- Own and evolve our monorepo, ensuring it stays healthy, performant, and easy to work in as the codebase grows

- Design, build, and maintain CI/CD pipelines for React Native and web targets, driving reliability and fast feedback loops for the engineering team

- Author and maintain shared TypeScript libraries — state management patterns, networking layers, error handling utilities — consumed across all frontend products

- Production-grade TypeScript - strong typing discipline, not just familiarity

- Practical Kotlin experience on Android - native modules, build configuration, or Android-side CI/CD work

- Direct involvement in CI/CD pipeline ownership or significant contribution — mobile or frontend, any tooling

- Ability to think in systems and write code for other engineers, not just end users

- Comfortable working autonomously and making decisions without waiting for full consensus

#### Nice to have (Optional)

- Hands-on experience with nx or pnpm workspaces specifically

- Familiarity with Vite and Expo for tooling or build configuration

- Exposure to Reanimated or React Native Gesture Handler

- Background in fintech or a high-scale consumer app where release reliability was business-critical

#### What we offer

- Challenges that will help you grow and realise your potential
