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 use deuterium and tritium for its fusion fuel. While deuterium has a high natural abundance, tritium will need to be made inside the ARC plant from the fusion neutrons and lithium in the blanket. The tritium will need to be separated from the blanket FLiBe molten salt and purified. Additionally, the tokamak exhaust, containing deuterium, tritium, helium, and other trace gasses, will need to be purified before the deuterium and tritium fuels are injected to the torus. The Tritium Expert will be involved in ARC tritium processing and storage system design, identifying technical gaps and risks, and working with CFS R&D and Open Innovation to close the gaps and risks towards a successful ARC tritium processing and storage system.
