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.
The Materials Test and Characterization Group at CFS is looking for an experienced materials test
engineer to support the ongoing design, engineering, and delivery of the SPARC net energy tokamak
being built in Devens, MA. Fusion energy systems require high performance materials in extreme
environments. The material properties and failure modes must be tested in similar extremes to
validate they will be able to meet the strict requirements. Materials test engineers will interface with
multiple stakeholders across CFS including design engineering, supply chain, electromagnetic
analysts, and more. We are seeking engineers with strong materials science fundamentals and
hands-on materials testing experience. Experience with a variety of material characterization, design
of experiments and interest in developing test methods are desired. Knowledge on performance of
materials at cryogenic temperatures is preferred.
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. We do not discriminate on the basis of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law, ordinance, or regulation.
