Brief: Commonwealth Fusion Systems (CFS), an MIT spinout pursuing the fastest, surest way to clean, limitless fusion energy, is looking for an engineer broadly skilled in designing, building, and operating cryogenic systems.

CFS’ mission is to enable world-wide clean energy for everyone, creating a sustainable environment for current and future generations. We’ve created a credible path to an operating fusion power plant in 15 years which leverages our novel collaboration with MIT and funding from strategic and financial investors who share our vision. This begins by developing a new class of high-field superconducting magnets that will enable the SPARC tokamak to demonstrate net energy from fusion for the first time. To execute this plan, we are now looking to add talented people to the team who:

  • are mission-driven and treat people well;
  • improve our team by adding diverse perspectives and new ways of solving problems;
  • have demonstrated exceptional results through a range of different pursuits; and
  • have skillsets and experience that relate to the following role:

Cryogenic Engineer

Cryogenic cooling is a crucial component of any superconducting magnet system. The Cryogenic Engineer will:

  • work within a multi-disciplinary team of physicists and engineers as part of collaborative sponsored research projects at the MIT Plasma Science and Fusion Center;
  • contribute to cryogenic engineering system design on the SPARC tokamak, including forced-flow supercritical helium, large-scale cryoplants, liquid nitrogen cooled systems, and vacuum cryostats;
  • lead cryogenic engineering, design, and operation of production magnets at CFS, typically using closed-loop cryocoolers; and
  • produce world-class superconducting magnets.

The ideal candidate will have:

  • designed, built, and operated a variety of cryogenic systems (cryocoolers, compressors, liquefiers, heat exchangers, pumps) from liquid helium (4 K) through liquid nitrogen (77 K), including force-flow, bath, and conduction cooling;
  • worked with superconducting magnets, although cryogenic experience in other areas will also be considered (e.g., aerospace propulsion, liquefied natural gas);
  • knowledge of ASME Pressure Vessel and Piping Codes;
  • an exceptional safety record and attention to detail;
  • at least a bachelor’s degree in a relevant engineering field (e.g., mechanical with focus on fluids), preferably with an experimental cryogenic-related thesis topic;
  • skill in modern computational design and engineering tools;
  • an ability to clearly express and critique ideas;
  • an emphasis on elegance and simplicity over complexity;
  • a drive towards commercially viable solutions;
  • a history of thriving in fast-paced, dynamic environments; and
  • values that align with our company’s values of integrity, execution, impact, and self-critique.

If you share our mission and believe you are a good fit for this position, please send a cover letter and resume to jobs@cfs.energy, with “Cryogenic Engineer” in the subject line.

At CFS, we deeply value diversity and are an equal opportunity employer by choice.
