Founding Design Engineer

What You'll Do

• Design and build features end-to-end: From Figma concepts to production React components. No handoffs, no waiting, 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: How do you display 500 extracted provisions across 200 contracts in a way that's actually usable? How do you make an AI-powered document review feel trustworthy? These are the kinds of problems you'll tackle daily.
• Obsess over details: Micro-interactions, loading states, keyboard shortcuts, error messages. The small things that separate "functional" from "delightful."
• Talk to users: Our users are M&A attorneys. You'll watch them use the product, understand their workflows, and design for how they actually work, not how you think they should.
