Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.
CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost.
The mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change.

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 Diagnostic Mechanical Engineer
The design of the SPARC facility is continually advancing, including the design of instrumentation that will be used to control the plasma and deliver the scientific data necessary to inform the design of ARC. The SPARC Diagnostic system is comprised of over forty sub-systems that use a variety of proven techniques to encode information from a tokamak plasma into measurable signals; active laser based measurements, passive and active analysis of microwave-band emission, spectroscopy of plasma emission from the x-ray to infrared, characterization of neutrons produced from fusion reactions, and a wide variety of wired sensors and probes integrated into the vacuum environment. Techniques have been demonstrated by decades of government-sponsored fusion research, and CFS is looking for multidisciplinary engineers who can contribute to innovative design and engineering solutions to endure these concepts can be integrated into the SPARC tokamak. Candidates that have design, build, or analysis skills in the mechanical, civil, or aerospace engineering disciplines are encouraged to apply. The SPARC diagnostic team welcomes engineers looking for a career transition who want to join a team with diverse backgrounds and can solve challenging problems in the growing fusion energy industry. Candidates will work alongside CFS staff, MIT-PSFC partners, and fusion community collaborators from around the world to design and build the tools that will control the SPARC plasma and measure net energy from a tokamak for the first time.
