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 an Assembly Process Engineer - Contract

As a SPARC Assembly Process Engineer, you will help create, define, instruct, and assist in managing the process by which we assemble the SPARC tokamak device. This will include collaborating with the system design teams on the sequence and key steps, organizing and designating how the various sub-assemblies will come together to create the larger whole, identifying assembly methods and tools required, and then writing these steps into work instruction packets for use by the assembly technicians to use in the field. You will work closely and collaborate with the other SPARC teams to find the most efficient, creative, cost-effective, and safest way to assemble each part of the tokamak. You will guide and organize how the giant parts of this multi-million pound “Swiss-watch” come together! This work is conducted within a multi-disciplinary team of physicists and engineers as part of collaborative sponsored research projects at the MIT Plasma Science and Fusion Center and within CFS.
