Staff Design Engineer

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. You have the rare combination of deep design sensibility and production engineering skills, and you’ll use both to help bring our AI product vision to life with craft and…
• 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.
