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.

To execute this plan, we are 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 skill sets and experience that relate to this role.
ARC will be the first machine to produce electricity from fusion energy, serving as the cornerstone to a new industry. A critical component of ARC is the molten FLiBe (mix of lithium fluoride and beryllium fluoride) salt blanket. This blanket serves three purposes: (1) as the primary working fluid it absorbs the energy of the fusion neutrons and transfers the energy to the heat exchanger, (2) breeds tritium, critical to the ARC fuel cycle, from the fusion neutrons and the lithium in the blanket, and (3) acts a coolant for the vacuum vessel. The tritium will need to be separated from both the molten salt blanket as well as from the other gasses from the tokamak exhaust. The Chemical Engineer Analyst will be responsible for developing and analyzing the early stage conceptual design for the ARC blanket and tritium processing systems. They will work closely with the SPARC Design Team on transferring analysis tools, techniques, and know-how to the ARC design. They will also work closely with the ARC R&D team to identify critical R&D needs as well as opportunities to close the ARC design.
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.
