Mechanical Engineering Team Lead
Cambridge, MA /
SPARC Team – Tokamak Systems /
Commonwealth Fusion Systems (CFS) is the surest path to limitless, clean fusion energy. Our mission is to enable world-wide clean energy for everyone, creating a sustainable environment for current and future generations. We have 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 this role.
In this role, your focus will specifically be on leading the ongoing mechanical design, analysis, and fabrication plan of the Vacuum Vessel, the structural heart of the SPARC Tokamak Fusion Device. This vessel structure sits at the center of the device, and it is within this central vacuum chamber that the plasma is created, contained, and controlled by the superconducting and copper magnet systems wrapped around and throughout the vessel structure. Beyond just containing the vacuum for the fusion reaction itself, tightly packed among the other critical components of the device, this structure must also allow expansion and contraction through regular thermal duty cycles, endure and dissipate heat pulses through the plasma-facing components from each plasma shot, and is subjected to enormous forces created from the interaction of evolving eddy currents generated in its skin and the surrounding magnetic fields.
This work is conducted within a multi-disciplinary team of physicists and engineers as part of collaborative sponsored research projects at the MIT Plasma Science and Fusion Center and within CFS.
This team member will:
- Lead the design and analysis for the Vacuum Vessel, Ports and Shielding
- Coordinate work with interfacing systems
- Determine the activities and milestones for the team to allow for a timely completion of the SPARC project
- Provide technical direction during the manufacturing
- Develop assembly and commissioning documentation
- Support the development of the tooling for assembly
- Support the resolution of technical issues that arise during the manufacturing, assembly and commissioning
- Prepare reports and presentations as requested
- Supervise the vessel team
The ideal candidate will have most, if not all, of these requirements:
- At least a bachelor’s degree in mechanical engineering, aerospace engineering, or another relevant field
- At least 2 years leading a highly technical team of at least 5 through a project of comparable complexity to the SPARC vessel and embedded systems
- Responsible for the delivery of at least one bespoken tightly-toleranced and large (typical dimension over 2m) fabricated component
- Solid knowledge of the fundamental of structural mechanics
- Understanding of manufacturing methods
- Exceptional attention to detail
- An ability to clearly express and critique ideas
- An emphasis on elegance and simplicity over complexity
- The ability to thrive in fast-paced, dynamic environments
- A drive toward commercially viable solutions
- Values that align with our company’s values of integrity, execution, impact, and self-critique
Additional experience and/or qualifications:
- ANSYS (preferred)
- NX (preferred)
- Scheduling and budgeting tools (preferred)
- Ability to sit for extended periods of time
- Willingness to travel occasionally as required
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.
