Job description

About Commonwealth Fusion Systems:
Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.
Combining decades of research, top talent, and new technologies, we’re designing and building commercially viable fusion power plants. And we're working with policymakers, suppliers, and many others to build the energy industry of the future.
We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world.
Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.
If that’s you and this role fits, we want to hear from you.
Join the power movement as Assistant General Counsel – Commercial

CFS is seeking an experienced, pragmatic, and highly strategic Assistant General Counsel – Commercial to serve as a foundational leader on our legal team. This is a rare opportunity to shape how legal operates at a company building an entirely new industry from the ground up.

This role is a true n of 1: you will be the company's dedicated commercial legal lead, operating as both a hands-on individual contributor on CFS's most complex, mission-critical transactions and the architect of the legal infrastructure that will support the company's next phase of commercial growth. As CFS scales, you will be expected to build and lead a team in commercial and corporate legal, making this as much a leadership opportunity as a technical legal one.

Reporting directly to the Chief Legal Officer, you will partner with executive leaders across commercial and business development, corporate development, strategic partnerships, supply chain, finance, and engineering — giving you direct visibility into, and influence over, the company's most consequential strategic decisions
