Materials Test Operator - Second Shift

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 Materials Test Operator – Second Shift

The Materials Department at CFS is looking for a materials test operator to support the materials testing and characterization laboratory. Materials at CFS supports the design and engineering of all components needed for fusion systems and high‑temperature superconducting magnets. Working closely with the team lead for materials testing and characterization, the team of materials test operators provides continuous support for both industry‑standard and customized material and component testing.

This includes communication between multiple internal stakeholders, detailed data reporting, equipment maintenance and upkeep, production line support, and continuous improvement. Current and future laboratory equipment includes, but is not limited to, mechanical and electrochemical testing, metallographic specimen polishing and preparation, visible-light and electron microscopy, high‑temperature heat treatments, static and dynamic mechanical testing in a wide range of environments (including cryogenic and high temperature), magnetic property evaluation, and other thermophysical tests.

The materials test operators will be responsible for conducting these tasks.
