Senior Product Designer, Design Systems

About the role

This is a dedicated systems design role focused on the experience layer of our design system. You'll define how our system, Thumbprint, translates into real product experiences, owning the patterns, flows, component compositions, and documentation that enable every team to design and ship with consistency at scale.

You'll work on a small team to evolve Thumbprint into a machine-readable, production-aligned system that accelerates product development from idea to prototype to shipped experience. The focus of this role is craft and usability: interaction quality, platform-native patterns, and the guidance that helps humans and agents apply our system across our various product experiences.

What You’ll Do

• Own the patterns, flows, and component compositions that power product experiences across iOS, Android, and web, ensuring consistency and quality at every layer
• Design and ship reusable components with a high bar for craft, including well-defined states, variants, responsiveness, and interaction models
• Define and maintain platform-native interaction patterns that make our product feel cohesive and intentional across surfaces
• Evolve Thumbprint over time to keep pace with modern UI patterns, platform conventions, and the changing needs of our product
• Create clear, opinionated documentation and usage guidance, including best practices, anti-patterns, and decision frameworks teams can act on
• Enable teams to adopt and extend the design system through onboarding, critique, and hands-on partnership
• Collaborate with technical partners to ensure Thumbprint works within AI-driven workflows, including Claude Code, Figma MCP, and our internal prototyping tools
• In addition, work closely with Engineering partners to define, align, and maintain parity between design components in Figma and their coded implementation, ensuring a seamless design-to-development workflow and single source of truth
• Contribute to the naming, taxonomy, and structure so Thumbprint is legible and usable by both people and AI tools
