Mechanical Engineer

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.

As a Mechanical Engineer for the SPARC Toroidal Field (TF) Coil System Structures team, you will be a product owner responsible for the design, production support, and assembly of structural components and insulation in our HTS magnet systems. You will work closely with our Production, Assembly, and Procurement teams to ensure components meet requirements and are delivered on-time. Your responsibilities will also include the development design and analysis documentation, technical specifications, and assembly procedures.

This team member will:

• Perform structural and thermal calculations, ranging in complexity from first principle hand calculations to FEA
• Drive production drawing releases and revisions to meet manufacturing and assembly schedules
• Collaborate with internal Quality, Manufacturing, Assembly, Commissioning, and Procurement teams on requirements and documentation
• Rapidly design, test, and qualify prototypes
• Prepare reports and presentations as requested
• Be self-motivated and exhibit excellent problem-solving skills
• Strive for simplicity over complexity

The ideal candidate will have most, if not all, of these requirements:

• Bachelor’s degree in mechanical engineering, aerospace engineering, physics, or another relevant field

• At least three years of experience designing structural components in a fast-pace environment

• Experience with CAD software (NX preferred) and analysis software (ANSYS Workbench preferred)

Additional experience and/or qualifications:

• Work in a facility that contains industrial hazards, including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
• #LI-Onsite

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.
