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 Materials Test Engineer

The Materials Test and Characterization Group at CFS is looking for a materials test engineer to support the ongoing design, engineering, and delivery of the SPARC net energy tokamak being built in Devens, MA. Fusion energy systems require high performance materials in extreme environments. The material properties and failure modes must be tested in similar extremes to validate they will be able to meet the strict requirements. Materials test engineers will interface with multiple stakeholders across CFS including design engineering, supply chain, electromagnetic analysts, and more. We are seeking engineers with strong materials science fundamentals and hands-on materials testing experience. Experience with a variety of material characterization, design of experiments and interest in developing test methods are desired.
