Lead Mechanical Engineer
Commonwealth Fusion Systems (CFS), an MIT spinout pursuing the fastest, surest way to clean, limitless fusion energy, is looking for a mechanical engineer with at least 10 years of experience leading teams through the design and commissioning of complex, integrated systems in extreme environments.
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 & 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:
Lead Mechanical Engineer
The SPARC tokamak will have a variety of mechanical engineering challenges, including structural engineering under extreme conditions, complex heat transfer (cryogenics down to liquid helium temperatures and plasma-facing components exposed to extreme plasma heat fluxes), non-linear electromagnetics (superconducting magnets and current leads), vacuum vessels, and general mechanical support systems (air, water, HVAC) in a tritium and nuclear environment.
The Lead Mechanical Engineer will:
- work within a multi-disciplinary and proven team of top MIT physicists and engineers as part of sponsored research projects in collaboration with the MIT Plasma Science and Fusion Center (PSFC);
- lead the engineering design team of mechanical systems for the SPARC tokamak, including all structural systems (tokamak core and internal components, seismic loads, remote maintenance), cryogenics, support systems, as well as tokamak fueling and pumping;
- ensure the design is in compliance with the Code of Record and established requirements;
- maintain interfaces with other engineering subsystems; and
- report on and be accountable for project progress to the head of SPARC device design as well as have regular engagement with the CEO and others in senior management positions.
The ideal candidate will have:
- led a small team of skilled engineers through at least one design, build, and operate cycle of a multidisciplinary mechanical system with multiple, tightly-integrated subsystems (e.g., 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;
- demonstrated skill in modern computational design and engineering tools;
- 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 environment; and
- values that align with our company’s values of integrity, execution, impact, and self-critique.
