About The Role
As a Software Engineer on our OfficeJS 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."
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.

We expect urgency, ownership, and good judgment even when things aren’t perfectly clear. If you need structure and consensus to do your best work, this isn’t the right place for you. If you thrive in ambiguity and growth, work with intensity, and want real responsibility, keep reading. We’re excited to meet you.
