Staff Design Engineer

At Mixpanel, we believe design excellence is a competitive moat. As a Staff Design Engineer at Mixpanel, you'll sit within the design organisation and lead the transformation of our design system from a component library into something far more important: the infrastructure that powers how we design, build, and ship in an AI-native world.

Responsibilities

• Build the infrastructure for an AI-native design practice
• Translate Mixpanel's design standards, principles, and taste into systems that live in the code
• Build a token system, component library, documentation, and guidelines that AI agents, AI coding tools, and AI prototyping workflows can reliably build on
• Evolve our design system to be foundational infrastructure for AI-assisted workflows
• Shape how Mixpanel looks and behaves in an AI-native world
• Sit within the product design team and collaborate on reimagining Mixpanel for a world where interfaces are conversational, agentic, and adaptive
• Own the bridge between design and code
• Build systems that connect design to code and keep the two in sync
• Define what 'shippable' looks like as AI writes more of the code
• Work directly in the codebase
• Ship PRs that improve the product
• Make design a force multiplier for engineering, not a bottleneck
• Stand up prototyping and AI tooling infrastructure
• Build the workflows, tools, and infrastructure that let designers and PMs prototype at high fidelity, with working code, real components, and interactive states, without waiting on engineering
• Identify the places where design and engineering lose time, intent, or quality in the handoff, and build AI-powered workflows that close those gaps
• Set and model the craft bar
• Establish what great looks like , not through documentation alone, but through the quality of what you ship
• Enable designers to work more code-adjacent and engineers to build with better components
• Stay ahead of how AI is changing EPD workflows and bring that change into the org responsibly

What success looks like

• The design system is a reliable foundation that AI tools and agents build on, not an obstacle they work around
• Design and code are in sync; the gap between what's designed and what ships is closed
• Designers can prototype at high fidelity without waiting on engineering
• Engineers spend less time on UI polish and rework, more time on features
• The Mixpanel product feels unmistakably itself , cohesive, expressive, and craft-forward , as it evolves into an AI-native experience
• The org is enabled on the latest AI-assisted design and development workflows

Qualifications

• Proficiency in modern front-end frameworks: React, TypeScript, JavaScript, CSS, HTML, Next.js
• Experience with design systems
• Strong design sensibility: you care about craft, consistency, interaction quality, and taste
• Fluency in AI-assisted workflows: canvas-to-code, code-to-canvas, AI prototyping tools, MCP integrations, and what's emerging in this space
• Experience working with tools like Figma, Storybook, VSCode, Chromatic, and GitHub
• A track record of working across design and engineering: you've done both, and you know how to collaborate across both
• Comfortable operating with high autonomy: you set direction, influence standards, and manage complex projects without a lot of hand-holding
• 8+ years in design engineering, UX engineering, design technology, or a related hybrid role
