Sr. Design System Engineer

• Build maintain and evolve a cross-platform design system spanning React components and web components with thoughtful composable APIs that prioritize developer ergonomics.
• Manage our design token architecture from primitive values to semantic and component-level tokens bridging Figma and code to ensure visual consistency across platforms.
• Build and utilize MCP tools skills AI agents and internal tooling that leverage the design system to accelerate product development. Make the system machine-readable so AI can compose UIs using our components correctly.
• Create and maintain documentation interactive playgrounds and component showcases that make adoption effortless. Mentor engineers across the organization on design system best practices.
• Champion accessibility and infrastructure: automated a11y testing WCAG compliance CI/CD pipelines visual regression testing versioning and release management.
• Collaborate deeply with product designers to bridge design intent and engineering implementation contributing to the design process from ideation through production.

• Deep in TypeScript and React including advanced patterns like compound components headless UI and controlled/uncontrolled APIs. Experience with (or strong interest in) web components and custom elements.
• Bachelor's degree in Computer Science or related discipline and 4 years' experience in a related field. The right candidate could also have a different combination such as a master's degree and 2 years' experience; a Ph.D. and up to 1 year of experience; or 16
  years' experience in a related field.
• A systems thinker. You've used component libraries understood their constraints and have opinions about what makes them good or bad. You naturally see patterns design for reuse and anticipate how your decisions cascade across a product.
• Familiar with design token tooling and workflows: Style Dictionary Figma variables/tokens token transforms and the full pipeline from design to code.
• Accessible by default. Strong understanding of WCAG and hands-on experience testing for accessibility across browsers and assistive technologies.
• Fluent in AI-assisted development. You already use AI tools in your day-to-day work whether that's MCP servers LLM tooling prompt engineering or agent-based workflows. The playbook for "design systems + AI" is being written right now and you want to help write it.
• Visually literate. You don't need to be a designer but you understand typography spacing color layout and motion and you have opinions about what makes software feel great.
