Senior Frontend Engineer, Design System
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Frontend Engineer, Design System based in United Kingdom.
This is a senior engineering opportunity focused on building the shared UI foundation that powers multiple products and teams.
You will own and evolve a modern design system spanning component libraries, design tokens, documentation, and developer tooling.
A key focus will be making the system AI-friendly so both developers and AI agents can create consistent, accessible interfaces by default.
You will work hands-on with React and TypeScript while shaping component APIs, performance, accessibility, theming, and localization.
The role combines deep frontend engineering with close collaboration across design, product, accessibility, and engineering teams.
You will influence technical direction, improve developer experience, and drive adoption of the design system across the organization.
This is an opportunity to shape a foundational platform at the intersection of frontend engineering, design systems, and AI-assisted development.
Accountabilities
- Build, scale, and continuously evolve the design system, including its component library, design tokens, documentation, and supporting tooling.
- Develop the system for AI-assisted development, enabling coding tools and AI agents to consume components, tokens, guidelines, and machine-readable interfaces effectively.
- Design robust component APIs that minimize misuse and make correct implementation intuitive for both human and AI developers.
- Write high-quality, performant frontend code using React and TypeScript while establishing strong standards for component quality and consistency.
- Partner with designers, product managers, and engineers to define components and take them from concept through production-ready implementation.
- Build accessible components aligned with WCAG 2.2 AA and incorporate accessibility best practices throughout the development lifecycle.
- Own the developer experience, including Storybook, documentation, guidelines, versioning, component APIs, and smooth migration paths.
- Implement and maintain theming, white-label capabilities, localization, and right-to-left support for a global user base.
- Monitor adoption, contributor feedback, and evolving platform capabilities to identify opportunities for continuous improvement.
- Help establish the technical roadmap and direction of the design system over the next 6-12 months.
- Champion adoption of shared components and best practices across engineering teams.
- Contribute to a culture of strong frontend engineering, thoughtful design, accessibility, and improved developer productivity.
