Job description

GC AI is the legal intelligence platform built for in-house legal teams and companies. Your decisions shape the product, your impact is immediate, and you own your work from day one.

More than 2,100 companies run their legal work on GC AI, including 300+ public companies, 75+ unicorns, and teams at Nestlé, Hitachi Digital, Lockheed Martin, Miro, Bass Pro Shops, Riot Games, SKIMS, Liquid Death, Vercel, TIME, and Post Holdings. The platform holds an 80 NPS, more than double the B2B SaaS industry average, reinforcing GC AI as the leading legal AI platform for companies of all sizes.

GC AI has doubled ARR in six months. We won #1 Highest Customer Satisfaction at the 2026 SaaS Awards. Our investors include Scale Venture Partners, Northzone, Sound Ventures, and Guillermo Rauch, CEO of Vercel.

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.

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 \"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.

A Note On Pace

We’re building something new in a once-in-a-generation shift in technology and the legal industry, so we move at a relentless pace. 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.

How We Work Together

GC AI is a distributed company with team members across North America, and soon Europe. We believe that because our business is AI, human connection matters more, not less. We invest in bringing people together through our hub model: regular coworking sessions, customer dinners, team and company offsites. If you’re in a location without an office, expect up to 10% travel (and more for customer-facing roles).

Team members in the San Francisco Bay Area and Provo, UT (within 50 miles of the office) work together on Tuesdays, Wednesdays, and Thursdays. As we grow, we plan to establish permanent offices in more hub cities, and we will look to our team members to help build that in-person culture. We currently hire across the United States and Canada.

We proudly offer the following benefits for our full-time employees:

• Medical, Dental & Vision — Comprehensive coverage for you and your family


• Life & Disability Insurance — Added protection when you need it most


• Retirement Plan — Plan and save for your future


• Parental Leave — Time to focus on what matters most


• Continuous Development — Up to $3,000/year for job-related learning & development
