The AI for in-house counsel

The Role

GC AI is the fastest-growing and most trusted legal AI platform for in-house legal teams. We're building the future of legal work, and we're doing it fast. You'll join at a moment when decisions matter, impact is immediate, and the runway to shape your career is wide open. We’re a high-performing team where you'll have real ownership and influence from day one.

More than 1,700 companies use GC AI to drive their business forward, including 150+ public companies, 25+ unicorns, and brands such as News Corp, Miro, Bass Pro Shops, Snyk, Skims, Liquid Death, Vercel, Zscaler, and TIME.

We've 10x'd revenue in 12 months, raised a $60 million Series B ($555 million valuation), and are growing faster than ever. We are backed by incredible investors, including Scale Venture Partners, Northzone, Sound Ventures, and Guillermo Rauch, CEO of Vercel.

If you thrive when the stakes are high and the path isn't paved, you'll love it here. Our six guiding principles are: 1% better every day, customer obsession, ship today, find a way, care deeply, and own it completely. Come shape the future of legal work with us.

Location

We are hiring for this role to be based in the United States or Canada. This is a remote role unless you fall within the following parameters. If you live within approximately 50 miles of our San Mateo, CA or Provo, UT office, the position follows a hybrid schedule with in-office days on Mondays, Wednesdays, and Fridays.

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."

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.

Compensation

GC AI's compensation package includes a competitive base salary benchmarked against real-time market data, as well as meaningful equity and excellent benefits for all full-time roles. Our US-based compensation range for this role is $165,000 – $350,000. This range spans four levels, from mid-level to Principal. Final compensation will vary based on leveling, market conditions, geographic location, and candidate qualifications, including relevant knowledge, skills, and experience assessed during the interview process.

These compensation bands are just the starting point. After someone joins and proves they’re an exceptional performer, we adjust quickly to ensure their compensation aligns with their impact.
