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 working with policymakers and suppliers to build the energy industry of the future. 

We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.

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 a Director of Process Engineering

CFS is designing SPARC, a tokamak able to achieve net energy plasmas. SPARC includes HTS and copper magnets, thermal shields, vessels and plasma facing components, all subject to large operational loads (thermal, electromagnetic, etc) and competing for space. These devices are supported by a plant with process systems that include cryogenic cooling, process utilities, fueling and vacuum systems. In the future, ARC will require molten salt and steam process systems.
