Brief: Commonwealth Fusion Systems (CFS), an MIT spinout pursuing the fastest, surest way to clean, limitless fusion energy, is looking for a mechanical engineering leader with significant experience in leading teams through the design, construction, and commissioning of complex, integrated systems. CFS’ mission is to enable world-wide clean energy for everyone, creating a sustainable environment for current and future generations. We’ve created a credible path to an operating fusion power plant in 15 years which leverages our novel collaboration with MIT and funding from strategic and financial investors who share our vision. This begins by developing a new class of high-field superconducting magnets that will enable the SPARC tokamak to demonstrate net energy from fusion for the first time. To execute this plan, we are now 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 skillsets and experience that relate to the following role: Head of Mechanical Engineering The SPARC tokamak will have a variety of mechanical engineering challenges, including structural engineering under extreme loads, a variety of complex thermal management problems (from cryogenics at liquid helium temperatures to solid plasma-facing components elevated to nearly their melting point), non-linear electromagnetics (superconducting magnets and current leads), large vacuum vessels, and general mechanical support systems (air, water, HVAC) in a tritium nuclear environment. The Head of Mechanical Engineering will: work within a multi-disciplinary team of physicists and engineers as part of collaborative sponsored research projects at the MIT Plasma Science and Fusion Center; lead the engineering design team of mechanical systems, as described above, for the SPARC tokamak; ensure the design is compliant with the Code of Record and established system requirements; maintain interfaces with other engineering subsystems; and report on and be accountable for project progress to the head of SPARC design as well as have regular engagement with others in senior management. The ideal candidate will have: led a small team of skilled, engineers through at least one design, build, and commissioning cycle of a multidisciplinary mechanical system with multiple, tightly-integrated subsystems (e.g., like those in aerospace/rockets, formula 1 and other high-performance racing, complex industrial plants, etc.); strong leadership abilities, experience building teams, and a talent for inspiring collaboration and execution; familiarity with engineering systems in extreme environments; an exceptional safety record and attention to detail; at least a bachelor’s degree in a relevant engineering field (e.g., mechanical); familiarity in applying ASME, ACI, ASTM, and other mechanical standards to design solutions; an ability to clearly express and critique ideas; an emphasis on elegance and simplicity over complexity; a drive towards commercially viable solutions; a history of thriving in fast-paced, dynamic environments; and values that align with our company’s values of integrity, execution, impact, and self-critique. If you share our mission and believe you are a good fit for this position, please send a cover letter and resume to jobs@cfs.energy, with “Head of Mechanical Engineering” in the subject line. At CFS, we deeply value diversity and are an equal opportunity employer by choice.
