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.

Tritium is generated (bred) in the molten salt used to cool ARC, which must be extracted from the salt and recycled as fusion fuel. However, such separation processes (e.g. gas-liquid absorbers, vacuum sieve trays) are at a low technical readiness level and present novel challenges because of the high operating temperature and low partial pressure of the dissolved gas. The tritium extraction (TEX) Engineer in this position will execute strategic and rigorous experiments to de-risk this system, starting at the level of sub-component development and eventually moving to larger-scale demonstration. Ideally, this engineer will also perform modeling to complement experimental work.

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.

At CFS, we deeply value diversity and are an equal opportunity employer by choice. We consider all qualified applicants equally for employment.
