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 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 nearly $3 billion in capital, making us the largest and leading private 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 a Senior Scientist – ARC Plasma Instrumentation

Commonwealth Fusion Systems is currently in the early stages of designing the ARC fusion power plant. The tokamak will share some attributes with SPARC but will also present many new challenges, especially in the thermal and radiological environment inside of the tokamak. The Senior Scientist, ARC Plasma Instrumentation will lead early efforts at scoping out necessary measurements in the plasma for plant control and the technologies that will be used to make these measurements. The Senior Scientist will build off what has been done for SPARC, with a particular focus on determining the minimum necessary set of measurements and instruments for a power plant. In many cases, novel techniques may be required in order to operate in the thermal and radiological environment, so the scientist will work closely with R&D teams to determine necessary R&D for this instrumentation. CFS is looking for someone with experience designing, building, and operating fusion diagnostics and with an interest in exploring a breadth of measurements and technologies for future power plants.

Determine and continually refine the set of measurements necessary to operate the ARC tokamak, coordinating with the plasma control and plasma physics teams

Evaluate potential techniques and technologies to make the measurements required in ARC, with a particular focus on techniques that will work robustly in the thermal and radiological environment in ARC

Determine which techniques and technologies will require significant R&D and work with CFS R&D teams to scope out what projects are necessary to develop these technologies

Develop early concepts, layouts, and requirements for proposed plasma instrumentation on ARC, including space requirements both inside and outside of the tokamak

Work with the remote maintenance team to ideate and evaluate remote replacement strategies for plasma instrumentation

Longer term, coordinate efforts of various engineering disciplines to design and analyze instrumentation concepts

Coordinate efforts of external collaborators on ARC plasma instrumentation

PhD in experimental plasma physics or a closely related field
