You’ll define how things get built, not follow someone else’s playbook. Six principles guide how the team works:

📈 1% Better Every Day: small, compounding improvements across everything you ship.

❤️‍🔥 Customer Obsession: start with the customer and work backward.

🚀 Ship Today: bias toward action and iteration over perfection.

🧗 Find a Way: resourcefulness and ambition over constraint.

🤝 Care: be direct, like an honest friend, even when it’s uncomfortable.

🎯 Own It: full accountability, proactive communication, and attention to detail.

About The Role

As part of our Microsoft Office Integrations 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 $60M at a $555M 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.

Obsess over latency, reliability, and the micro-interactions that make the difference between "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
