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 Director, Manufacturing, Operations & Supply Chain Finance

We are seeking a strategic and analytical Director of Manufacturing, Operations & Supply Chain Finance to lead our operations finance team.

The Director of Manufacturing, Operations & Supply Chain Finance will manage a team of finance business partners, owning finance support across the plants/BUs, and allocations across a matrixed Operations team. As CFS shifts from proving fusion to manufacturing it, this key role will build the operations-finance leadership that turns the breakthrough into economics that support scalability.

Standardize and own the standard-costing framework, ensuring cost roll-ups, and unit-cost tracking across the plants; oversee analysis of purchase price variance, absorption, yield, scrap, and capacity utilization
