About the Role

At Klaviyo, we're building the platform that helps businesses create and deliver personalized customer experiences at scale, powered by first-party data.

We’re looking for a Senior Product Designer to join the Design System team and help evolve Ascent, Klaviyo’s design system. You'll define and scale the reusable components, patterns, tokens, documentation, and standards that help teams ship faster, creating a more consistent and usable product experience across Klaviyo.

This role sits at the intersection of product design, engineering, and systems thinking. You'll partner across product teams to improve design-to-code parity, drive adoption, and use AI and automation to reduce manual friction while maintaining a high bar for quality, accessibility, and system integrity.
