What You Will Own

• Token architecture in Figma: variables, modes and semantic naming, from primitives to semantic to component level.
• Component libraries that hold up across an entire site, not just a homepage.
• Handoff and documentation that let a developer or a build pipeline execute the system without questions.
• Several client brands at once, each distinct, with the same structure underneath.

What You Bring

• 4+ years as a product, UI or design systems designer, ideally on an in-house team.
• A design system you personally built in Figma with variables, modes and tokens, and can walk us through in detail.
• Experience handing a system to developers and keeping Figma and code in step.
• Strong spoken English. You will present and defend your system on live calls with a US team.
• Full-time availability overlapping US business hours.

Not a fit if

• You freelance or run a studio and would keep clients alongside this job.
• Your work is mainly page layouts or marketing pages, without tokens or variables.
