CRYP Engineer

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.

CFS collaborates with MIT to leverage decades of research combined with groundbreaking new high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible. To that end, 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. To implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.

The SPARC tokamak will be the first net-energy fusion reactor and a key steppingstone towards CFS’ first commercial fusion powerplant. The SPARC tokamak has passed conceptual design and ground has been broken on the reactor site. Moving forward, the device requires engineering complex integrated systems at the limits of materials performance and capabilities and will feature a large-scale cryogenic plant and cryodistribution system to deliver low-temperature gaseous helium to various tokamak subsystems. The cryogenics system is a critical utility for ensuring the tokamak high-temperature superconductors (HTS) meet performance requirements.
