We are backed by incredible investors, including Scale Venture Partners, Northzone, Sound Ventures, and Guillermo Rauch, CEO of Vercel. Come build the future of legal AI with us!

About the Role

You know how Cursor changed the game for software developers? We're building that for lawyers. As a Software Engineer on our Cursor for Contracts team, you'll be at the center of the most ambitious product in legal AI: GC AI for Word, the AI copilot that lives where lawyers actually work.

You’ll be crafting the experience that lets in‑house legal teams surgically redline contracts, draft clauses on the fly, and spot risks in seconds, all without leaving Microsoft Word. You’ll work directly with our founding team (including a 3x General Counsel who knows exactly what lawyers need) and a tight group of exceptional engineers to ship features that make lawyers say “Wow, this is magic.”

Why This Role Matters

The legal AI space is exploding, and we're in pole position. We’ve raised $60 M at a $555 M valuation because we've built something lawyers actually love. Now we need an engineer who can help us pull even further ahead. You’ll own the surface area where AI meets the document. Every redline, every clause suggestion, every risk flag, that's your canvas. The decisions you make will directly shape how thousands of lawyers experience AI in their daily work.

What You’ll Do

• Build and refine our Microsoft Word Add‑in
• Obsess over latency, reliability, and the micro‑interactions that make the difference between a “useful tool” and “can’t live without it.”
• Architect the bridge between our AI backend and the Word document model, handling everything from tracked changes to comment threads
• Ship features like playbook‑driven reviews, clause libraries, and contextual drafting that outpace the competition
• Collaborate with our AI team to integrate model outputs in ways that feel native to the legal workflow

Impact You'll Have

• Define the UX patterns for AI‑assisted contract work that the entire industry will follow
• Build the product that turns hour‑long contract reviews into 10‑minute workflows
• Ship features that directly drive enterprise adoption and make IT teams say “yes” faster
• Help further GC AI’s position as the undisputed leader in legal AI for in‑house teams

Required Experience

• 5+ years building production software, ideally with a focus on rich client applications or editor experiences
• Strong expertise in TypeScript and React
• Experience with Microsoft Office Add‑ins, VS Code extensions, or similar embedded application development
• Deep understanding of real‑time collaboration patterns and document manipulation
• Track record of shipping polished, user‑facing features that people actually love

Nice to Have

• Experience with Office.js or the Microsoft Graph API
• Background in legal tech, document automation, or CLM platforms
• Familiarity with LLM integration patterns and streaming responses
• You’ve used Cursor, Copilot, or similar AI coding tools and have opinions about what makes them great
