Commercial Counsel

Rebuild how the world works, to make institutions work better for the people they serve.

Brain Co. builds AI-native operating systems for large, regulated institutions. Each system is built for a specific industry, powered by agents that push real workflows forward. Underneath it all is Atlas, our proprietary platform that keeps customers in control, secure by design, and never locked into one model.

Brain Co. is entering its next phase of production deployments on a national scale with an elite team built from Palantir, Google, Meta, and Nvidia, and a growing footprint across government, insurance, health, and financial services.

Joining now means shaping both the company and a new category of applied AI. Every project here ships to production and is expected to create measurable customer value and impact.

You'll work alongside exceptional peers on some of the hardest problems in applied AI. It’s the kind of work you'll still be proud of in ten years from now.

Brain Co. is hiring an exceptional, business-minded deal lawyer to be our first in-house attorney and build our Legal foundations. You will work alongside key partners throughout the company — including Sales, Business Development, Finance, and the executive team — to close first-of-kind strategic partnerships and high-value deals. You’ll work on a wide variety of deal types, many of which open new routes to market for Brain Co. across government, regulated industries, and major enterprises. You’ll also be the lawyer on major deals and projects that make an immediate impact on our fast-growing, dynamic business. Above all, you’ll help our business partners and executives solve problems and take down roadblocks.

We’re looking for an experienced lawyer with a strong work ethic, excellent analytical and communication skills, and incredibly solid fundamentals as a lawyer. The ideal candidate is creative and thinks outside-the-box, is a self-starter who takes ownership over initiatives, and is hands-on taking into consideration the lowest level of detail.

This role reports to the COO. Approximately 95% of the work is substantive commercial legal; the remaining ~5% is product advisory support for Brain Co.’s legal AI tools. There’s meaningful room to grow the scope and the function over time.
