Job Description

• 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.
