Senior Frontend Engineer (Kotlin) - Frontend Core

• 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

Our mission is to enable everyone to build wealth

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 6 million clients, with more than €50 billion in assets under management - a testament to the scale and trust we've built in just a few years.

• 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
