• Work in an Agile team, translating UX designs from tools like Figma into high-quality code.
• Drive performance tuning and ensure the library scales efficiently across various internal platforms.

What we’re looking for

• Expert in React (Hooks, Context, Design Patterns) and TypeScript.
• Deep understanding of native Web Components standards.
• Proven experience building scalable component libraries and state management systems.
• Proficient with Storybook, ESLint, Prettier, Docker, and GitHub Actions.

• Excellent communication skills in English.
• Based in the Netherlands (no relocation).
