About the role

Mage automates legal due diligence for M&A attorneys. We're hiring a design engineer to own how the product looks, feels, and works. You'll design features in Figma, then build them yourself in our React codebase. No handoffs.

Responsibilities

  • Design and build features end-to-end: From Figma concepts to production React components. No handoffs, you ship the whole thing.
  • Own the design system: We have a component library built on Radix UI, Tailwind CSS, and tailwind-variants. You'll evolve it as the product grows.
  • Solve hard UX problems: Display 500 extracted provisions across 200 contracts in a usable way; make AI-powered document review feel trustworthy.
  • Obsess over details: Micro-interactions, loading states, keyboard shortcuts, error messages.
  • Talk to users: Observe and design for how M&A attorneys actually work.

Qualifications

  • You've shipped real product UI, not just component libraries
  • You design and build — Figma to production React, no gap in between
  • You think in systems and care about consistency across an entire app
  • You make complex, data-heavy interfaces feel simple
  • You notice the details: loading states, error messages, transitions, empty states
  • Strong with Tailwind CSS and component architecture
