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. The 14 MeV neutrons from deuterium tritium fusion in ARC will be a challenging environment for solid materials. While ARC is being designed with a FLiBe molten salt blanket to reduce the volume of solid materials exposed to fusion neutrons, the vacuum vessel and internal components will be solid and subject to intense neutron bombardment. While the blanket tank and superconducting magnets are significantly shielded from the fusion neutrons, nuclear effects on these materials should still be understood. The Fusion Nuclear Materials Expert will be involved in ARC nuclear materials development, working closely with engineers to down-select materials, and designing ARC components exposed to the nuclear environment to retire technical gaps and risks. We are seeking experimental and computational nuclear materials experts in the following areas: structural material design and qualification, plasma facing materials and plasma-material interactions, advanced manufacturing and joining for nuclear components, and molten salt corrosion and mitigation.
