About The Role

We’re seeking an exceptional Member of Technical Staff, Applied AI to help lead the development of our cutting-edge AI platform.

This is a unique opportunity to shape how artificial intelligence transforms legal work.

As our AI Engineer, you’ll be the architect of systems that make this transformation possible.

• Improve real-world outcomes (precision, recall, latency) by advancing RAG, structured reasoning, and tool-use pipelines.
• Translate domain insights into AI-powered product features that users immediately feel - better answers, fewer edits.
• Help build the leading legal AI platform for in-house teams.
• Required Experience

• Track record of technical publications or open-source contributions.
• Experience with multi-agent AI systems.
• The Mindset
• Problem Solver: You come alive tackling complex challenges without obvious solutions.
• Ownership-Driven: You take initiative without needing direction and focus on outcomes.

• Travel Expectation

GC AI is distributed, and engineering is our most distributed team.

We hire engineers across the US and Canada.

Wherever you’re based, expect up to 10% travel for coworking sessions and team off-sites across our hub cities.

Because we work across time zones, we prioritize engineers who communicate clearly in writing and operate well asynchronously.

Strong written communication is a core part of how we build.

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.
