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 Head of Plasma Physics

Commonwealth Fusion Systems is looking for a Head of Plasma Physics to lead the plasma physics research team, with a mandate to define, prioritize, and drive research that pushes our understanding of the plasma physics which is needed to design, support, and enable improvements in generations of ARC power plants. This will require standing up an excellent research team, extensive collaboration inside CFS, as well as collaboration and partnerships across the world wide plasma physics ecosystem.

CFS is currently building the SPARC tokamak, which aims to be the first magnetic confinement device to achieve net energy and is predicted to have up to Q=11 in DT, producing up to 140 MW of fusion power. In parallel, CFS is advancing the conceptual design of the ARC fusion power plant, which intends to operate commercially in the early 2030s and produce 400 MW of net electricity. To achieve these goals, CFS will need a robust Plasma Physics Program that develops the plasma physics knowledge and skills necessary to design, commission, operate, and improve plasma performance in magnetic fusion power plants. The new Head of Plasma Physics will have the opportunity to manage and grow a team of world-class scientists and set the strategic direction for this critical group at CFS.

What you’ll do:

Improve, prioritize, and execute the plasma physics research roadmap made in consultation with product leaders inside CFS that contributes to the overall CFS path to fusion energy
Work across teams inside of CFS to ensure that the roadmap is executable and focused on what is important to advancing the physics understanding needed for the ARC product
Evaluate benefits of potential upgrades to SPARC and help to develop their physics basis to support detailed engineering design
Ensure research leads to design tools and predictive capabilities that help CFS advance toward economical fusion power plants as rapidly as possible
Develop and expand external relationships and private-public partnerships with the broader plasma physics research community to accelerate the delivery of fusion energy
Ensure CFS maintains access to the knowledge, data, and experimental facilities that the plasma physics community shares
Build and grow a team of world class plasma research scientists
Ensure the right balance of conceptual, deeply technical, and operational individuals
Participate in developing training programs that ensure we can internally grow needed talent when needed skills and knowledge are hard to hire for
Manage and allocate the plasma physics program budget as appropriate
Manage a team of physicists at CFS and coordinate with multiple collaborator institutions

What we’re looking for:

PhD in experimental plasma physics or a closely related field
10+ years experience in plasma physics or fusion research
Experience planning and executing experiments on tokamaks
Experience managing a team of scientists working on multiple projects in a variety of topical areas
Experience setting long-term research priorities for a research group or scientific facility
A desire for active participation in tokamak design and operations
Ability to adapt to a rapidly changing environment
Ability to manage collaborations from a variety of academic institutions

Bonus points:

Involvement in research program or project review panels

Essential Requirements:

Perform activities such as typing, standing, or sitting for extended periods of time
Willingness to travel or work required nights/weekends/on-call occasionally
Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics
