Job summary

Trading212 is seeking a Staff Frontend Engineer to shape architecture and engineering direction across product teams. You will own shared libraries, platform capabilities, developer tooling and cross-team decisions while staying hands-on when needed.

This role emphasizes technical judgement, execution, and enabling other engineers to work more effectively. You’ll collaborate closely with product, backend engineering and QA to manage risk and drive quality.

Qualifications

• 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.

• 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.
