Key skills

The Staff Frontend Developer role demands deep expertise in React for both web and native applications, with strong proficiency in React Native, Expo, and associated EAS tooling. Candidates should possess extensive experience in frontend architecture, particularly in designing and owning unified platforms that consolidate multiple products. A TypeScript-first development environment is central, alongside familiarity with state management, testing, routing, and deployment strategies. The role requires hands-on experience building and maintaining shared infrastructure such as component libraries, build pipelines, and developer tooling to enhance automation and documentation. Knowledge of mobile CI/CD pipelines and native abstraction layers is important to support mobile app delivery. Collaboration skills are critical, as the developer will work closely with engineers, product teams, designers, and leadership to align frontend initiatives with product roadmaps and drive adoption of shared architectural patterns and design systems. Leadership responsibilities include technical consultations, pairing sessions, code reviews, workshops, and architecture discussions to foster knowledge sharing and improve developer experience. Additional valuable skills include managing multi-brand frontend architectures, working with monorepo tools like Turborepo or Nx, and experience with merger or post-acquisition platform consolidation. Strong English communication skills, both written and spoken, are essential for effective cross-functional collaboration. The position is based in major European cities with flexible remote options and emphasizes equal opportunity employment.
