Senior Frontend Developer (m/f/d)

We're looking for a Senior Frontend Developer to take a lead role in building and evolving our Shared Design Library - a core set of reusable React components, design tokens, and UX patterns that power our applications. This role requires someone highly technical and self-driven, who excels at communication and collaboration.

• Lead the implementation of a Shared Design Library with reusable React components, design tokens, and UX patterns used across applications
• Define the foundations of the library: naming conventions, versioning strategy, theming, accessibility standards (WCAG), and contribution guidelines
• Set up and maintain component documentation with usage guidelines and live examples
• Establish governance for proposing, reviewing, deprecating, and evolving components in partnership with UI/UX Designers and QA
• Define and implement a testing framework/strategy: component unit tests, visual regression, accessibility checks, and integration tests
• Collaborate with Product Designers to translate guidelines into tokenized, testable components, ensuring consistency across apps
• Integrate the library into CI/CD pipelines with automated builds, tests, visual regression, and versioned releases
• Write clean, maintainable, scalable code in TypeScript and React, building responsive, reliable, and secure web applications
• Own feature development from idea to deployment, aligning closely with product, design, backend, QA, and BA teams
• Review code, challenge assumptions, and help raise the technical bar across the team
• Mentor less experienced engineers and support team growth through technical guidance
• Help shape frontend architecture and long-term decisions (modularity, patterns, performance)

• 5+ years of professional experience in frontend development
• Expertise in TypeScript, modern JavaScript, and the React ecosystem
• Experience designing or contributing to a design system or shared component library
• Solid understanding of HTML5, CSS3, responsive design, web security, performance, and accessibility best practices
• Experience designing or contributing to scalable frontend architectures
• Comfortable in a fast-paced, iterative, CI/CD environment
• Proficient with Git, npm/yarn, and modern frontend tooling
• Strong communication skills, valuing direct feedback and open dialogue
• Supportive team player who actively shares knowledge and mentors colleagues
• Able to navigate ambiguity and adapt to changing priorities
