About the role
Full text from the employer, as published on Arbeitnow, arranged into sections. Nothing added or removed.
01Our mission is to enable everyone to build wealth
We reinvent how trading and investing work by creating exceptional products people love.
That takes high standards, high velocity and engineers who own what they ship.
Today, we serve over 6 million clients, with more than €38 billion in assets under management. At that scale, frontend performance, correctness and clarity are part of the product.
Our frontend platform spans web and mobile: TypeScript, React, React Native and React Native Web in an Nx and pnpm monorepo, with TanStack Query, Zustand, Playwright, Detox and Jest. Around 95% of our code is reused across web and mobile.
02About the role
Senior Frontend Engineers work across our product domains. Your team match will reflect your strengths, interests and where you can contribute most.
Across every team, the model is the same: small, autonomous groups, a weekly release cycle and ownership from problem definition through production.
03What you’ll do
Own complex frontend features end to end across web and mobile.
Design and evolve React and React Native systems, shared libraries and durable abstractions.
Identify and resolve rendering, state-management, bundle and runtime-performance bottlenecks.
Use TypeScript to make behaviour explicit and prevent defects rather than suppressing type errors.
Work closely with product, backend engineering and QA to turn complex requirements into simple user experiences.
Keep quality high through code review, unit, end-to-end and visual-regression testing.
Share knowledge, mentor colleagues and raise the frontend engineering standard.
04What you need to have
Proven ownership of production frontend systems built with React or React Native and TypeScript.
Strong knowledge of React rendering, component boundaries, data flow and state management.
A track record of designing maintainable frontend architecture and reusable abstractions.
Practical experience diagnosing performance problems in complex web or mobile products.
Sound testing judgement across unit, end-to-end and visual-regression coverage.
Clear, structured problem-solving and the ability to explain technical decisions and trade-offs.
Strong engineering fundamentals, product judgement and confidence learning unfamiliar technologies.
Depth in one frontend ecosystem and sound tool choice matter more than familiarity with every technology listed.
05What to expect
Recruiter conversation
Code Review
Experience Deep Dive
Managerial interview
Your recruiter will explain each stage clearly and follow up after every conversation.
Bring your ambition to Europe’s fastest-growing mobile broker!
