Apply existing design tokens and foundations consistently and correctly across all components

Produce clear, scalable component documentation that supports fast adoption by design and engineering

Partner closely with engineering to support implementation, QA, and iteration of system components in production

Apply the design system directly to dashboard features to validate system decisions in real workflows

You Have

4+ years of product design experience with significant hands‑on work in design systems

Demonstrated ability to build and ship design systems at speed—not just contribute occasionally
