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
