Extreme Environment Pump - Senior R&D Engineer

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.

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.

ARC will be the first machine to produce electricity from fusion energy, serving as the cornerstone to a new industry.  ARC will strongly leverage the work that’s been done for SPARC in developing HTS magnets and other key tokamak systems. However, because of its mission to deliver power to the grid, the ARC tokamak has several systems not included on SPARC. The ARC group within R&D is a growing team that is delivering key scientific and engineering results to push the Technology Readiness Level (TRL) of these new enabling technologies higher.

ARC will use a fluoride-based molten salt as the blanket working fluid. This senior R+D engineer will perform pump design and analysis work, fabricate and operate pump test stands, and gather and interpret data. They will also perform a trade-space analysis of possible pump technologies for high temperature, corrosive application to meet requirements,.  As the project and team grows, this engineer will be expected to work collaboratively towards the development of various component test flow loops and engage deeply with industry partners towards manufacturing pumps for ARC. 

CFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits. We all tightly align with our company values of integrity, execution, impact and self-critique. As we grow, we are looking to add talented people who are mission driven and bring diverse perspectives and new ways of solving problems.
