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 Materials Test Operator

The Materials Department at CFS is looking for a materials test operator to support our mechanical testing and characterization laboratory. Materials at CFS supports the design and engineering of all components needed for fusion systems and high-temperature superconducting (HTS) magnets. Working closely with the team lead, the materials test operator provides continuous support for both industry-standard and customized mechanical testing—including tensile, compression, flexural, shear, and fatigue. This role balances rigorous mechanical data acquisition and equipment operation with essential metallographic specimen preparation and microscopy. The operator is responsible for communication with internal stakeholders, detailed data reporting, equipment maintenance, and production line support. Laboratory capabilities include, but are not limited to: mechanical testing (Universal Testing Machines such as Instron, Load Cells, Extensometers), metallographic specimen polishing and preparation, microscopy, heat treatments, magnetic property evaluation, and other thermophysical tests.
