About the role

  • Immerse yourself in Kit's product surfaces and current component landscape in your first week.
  • Audit the current UI for patterns, tokens, and inconsistencies in your first month.
  • Establish tokens and primitives mapped between Figma and code in partnership with the front-end engineering team in your first six months.
  • Create a stable, predictable design-to-code workflow that feature squads rely on in your first year.
  • Drive high adoption of system components in new feature work with visible consistency improvements across surfaces that previously diverged.
  • Lead the evolution of our component library in Storybook to become the canonical reference for UI behaviour and states.
  • Establish guardrails that prevent UI drift before it starts, allowing feature squads to ship faster with higher-quality UI without needing to check in with you on every decision.

Requirements

  • 6+ years of relevant experience with meaningful design system work as a significant part of that — building, scaling, and maintaining a design system in production
  • Proven track record retrofitting and modernizing legacy UI systems, migrating inconsistent patterns into cohesive design systems
  • Prior experience working as a designer
  • Portfolio demonstrating effective use of UI design fundamentals
  • Deep experience with composition and presentational component architecture in React
  • Proven track record maintaining Storybook as a canonical UI reference
  • Built and managed design token systems with Figma integration
  • Evidence of successfully bridging design and code in a live product
  • Experience collaborating with product designers and engineering teams
  • Hands-on experience implementing AI tooling to accelerate design-to-code workflows and automate design system consistency checks
  • Strong visual design craft: typography, layout, spacing, color, and hierarchy
  • Strong React/Typescript fundamentals and component architecture
  • Design token architecture and Figma-to-code mapping
  • Building and maintaining Storybook for component development
  • Deep understanding of interaction design, states, and edge cases
  • The ability to spot and resolve visual and interaction inconsistencies across a product surface — not just in isolation, but in context
  • Performance and accessibility standards
  • Systems thinking and building for scale
  • Clear documentation and pattern guidance
  • Ability to validate technical feasibility early in the design process.
