Summary Generated by Built In

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 €38 billion in assets under management, a testament to the scale and trust we’ve built in just a few years.

Our frontend spans iOS, Android, and Web — all powered by a shared React Native monorepo.

We offer remote or hybrid working, depending on role, with flexibility balanced against team performance and collaboration needs.

What you'll do:

  • Lead the technical direction of a key frontend domain — spanning mobile and web — across the full product lifecycle, from shaping requirements through to delivery, monitoring and ownership.

  • Drive the architecture of our frontend monorepo, making decisions that improve efficiency, performance and code reuse across iOS, Android, Web and Desktop.

  • Lead a compact, autonomous, cross-functional team with short release cycles. Identify and develop your teammates' strengths through active mentorship and coaching.

  • Develop solutions by taking a holistic approach to problem-solving — understanding business goals, UX constraints, platform limitations and the underlying architecture.

  • Build for performance, accessibility and resilience — your code reaches millions of users and must perform reliably across a wide range of devices and conditions.

  • Take the initiative to identify and drive improvements in product and engineering, raising the quality bar across the frontend organisation.

What you need to have:

  • Experience leading the development and release of a complex, high-demand client-facing frontend product.

  • Experience leading, coaching and mentoring software engineers toward delivering high-quality software.

  • Deep expertise in TypeScript and React Native (or React/Next.js).

  • Advanced knowledge of state management patterns and solutions — TanStack Query, Zustand, Redux/RTK, or similar.

  • Strong understanding of cross-platform frontend issues such as performance optimisation, rendering, animations, and offline behaviour.

  • Experience designing scalable frontend solutions.

Nice to have:

  • Experience with monorepo structures and shared component systems.

  • Experience with native mobile development (Swift/Kotlin).

  • Experience with CI/CD pipelines and developer tooling at scale.

  • Experience with Reanimated/RNGH for complex animation and gesture handling.

  • Experience with WebSockets or other real-time data patterns.

  • A strong product mindset that can seamlessly bridge the UX design with technical reality.

What we offer:

  • Challenges that will help you grow and realise your potential.

  • Opportunity to make a big impact — you will lead innovative engineering 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 and 25 days of paid vacation per year.

All applicants will be contacted, regardless of whether they are selected!
