Staff Frontend Engineer

Description

**Our 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 architecture, performance and product quality have material business consequences. 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. **About the role** ------------------ Staff Frontend Engineers shape architecture and engineering direction across product teams while remaining close to the code. Your scope will include shared libraries, platform capabilities, developer tooling and difficult product\-system problems. This is not a people\-management role. Its leverage comes from technical judgement, credible execution and making other engineers and teams more effective. **What you’ll do** ------------------ * Set direction for frontend architecture across React, React Native and the shared monorepo. * Own cross\-team problems in platform capabilities, shared libraries, design\-system foundations, tooling and developer experience. * Lead decisions on boundaries, abstractions, state and data flow, performance, testing and migration strategy. * Diagnose systemic rendering, bundle, runtime and release\-quality problems and create durable fixes. * Remain hands\-on where implementation, prototyping or technical investigation is the fastest way to create clarity. * Partner with product, backend engineering and QA on risks and decisions that cross team boundaries. * Mentor senior engineers, raise review quality and make sound frontend judgement easier to reproduce across teams. * Balance standardisation with team autonomy, avoiding platform work that creates more friction than leverage. **What you need to have** ------------------------- * Evidence of architectural or platform impact across multiple frontend teams. * Deep ownership of complex production systems built with React or React Native and TypeScript. * Strong judgement in application boundaries, shared libraries, state management, performance and migration design. * A track record of improving developer effectiveness, reliability or product quality through durable mechanisms. * Practical experience diagnosing performance and correctness problems across web or mobile systems. * The ability to influence technical direction through evidence, clarity and trusted execution rather than title. * Clear communication that helps teams act on complex technical decisions. * Strong engineering and product judgement, including knowing when not to introduce a new abstraction. ***Staff scope is assessed through ownership, judgement and sustained organisational impact—not years of experience or familiarity with every technology listed.*** **What to expect** ------------------ * Recruiter conversation * Code Review * Experience Deep Dive * Managerial interview Your recruiter will explain each stage clearly and follow up after every conversation.
