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, suppliers, and many others to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading 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 Staff Dimensional Engineer – SPARC

SPARC is a first-of-a-kind machine, and it presents some of the hardest dimensional management problems in industry today: large high-field magnets, tight tolerances on complex geometries at meter scale, novel materials, and assembly stack-ups with no precedent to copy from. CFS is seeking a Staff Dimensional Engineer to be the technical authority for dimensional management across HTS Magnet production and the SPARC project.

This is a role for someone who wants to define a discipline, not inherit one. You will own how design intent becomes buildable, verifiable hardware: setting GD&T and datum strategy with Engineering, analyzing variation propagation through assembly sequences before hardware proves it the hard way, and defining what we measure and to what acceptance criteria. Your decisions will shape how fusion hardware is toleranced, measured, and accepted, on SPARC and on the ARC power plants that follow.

You will work alongside a metrology team equipped with laser trackers, portable CMM arms, and structured-light scanning, and with an established Quality Engineering organization that owns statistical process control and measurement system analysis, so your focus stays on the geometry.
