We reinvent how trading and investing work by creating exceptional products people love.
Fostering a culture of excellence and high velocity is the key to our success.
Today, we serve over 5 million clients, with more than €30 billion in assets under management - a testament to the scale and trust we’ve built in just a few years.
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
- Own the mobile release process end-to-end, including Android build configuration, versioning, and deployment automation
- Integrate and maintain observability tooling (Sentry, Amplitude) at the platform level, so product teams get reliable instrumentation out of the box
- Identify and resolve build bottlenecks, dependency issues, and tooling gaps that slow down engineering velocity
- Collaborate closely with product frontend teams to understand their pain points and translate them into platform improvements
- At least 4 years of professional experience in frontend or mobile engineering, with a meaningful portion spent on platform, infrastructure, or developer tooling work
- Production-grade TypeScript - strong typing discipline, not just familiarity
- Hands-on React Native experience in a production app, including an understanding of the native layer
- 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
- 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
- Challenges that will help you grow and realise your potential
- Opportunity to make a big Impact - you will build innovative services used by millions of investors to build wealth
- Work with smart, spirited, helpful, high-performing colleagues with a common goal
- An environment where nothing is set in stone
- Appreciation for your talent and ideas
- Generous remuneration package including annual bonuses
- Excellent social benefits package, including private health insurance, sports card and 25 days of paid vacation per year
- Delicious treats and a spacious game room
