Job summary

Mixpanel is seeking a Staff Design Engineer to lead the transformation of our design system into the AI-native infrastructure that powers how we design, build, and ship. You will encode craft and standards into token systems, component libraries, and tooling that AI agents and prototyping workflows can rely on.

Qualifications

• Proficiency in modern front-end frameworks: React, TypeScript, JavaScript, CSS, HTML, Next.js.

• Experience with tools like Figma, Storybook, VSCode, Chromatic, and GitHub.
• A track record of working across design and engineering, collaborating across both disciplines.
