Senior Mechanical Engineer – In-Vessel Coils

About Commonwealth Fusion Systems:

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent and new technologies, we’re designing and building commercially viable fusion power plants. And working with policymakers and suppliers to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.

Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.

If that’s you and this role fits, we want to hear from you.

Join the power movement as a Senior Mechanical Engineer – In-Vessel Coils

As a Senior Mechanical Engineer for the SPARC In-Vessel Coils, you will develop design notes, technical specifications, assembly procedures and documentation necessary to manufacture and install the in-vessel coils.

What you'll do:

• Develop technical specifications, assembly procedures and documentation necessary to fabricate and install the parts
• Produce refined design concepts for efficient manufacturing and in time delivery with cost in mind is critical
• Author, review and approve design notes, technical specifications, regular reporting, assembly procedures and documentation necessary to fabricate and install the parts
• Work closely with design team and maintain regular contact with the selected vendors to provide them with necessary technical support.
• Enforce observance of the required quality standards and securing documentation and processing of the NCR’s
• Offer insight and creative ideas about designed features and machining processes that can meet the basic requirement, with quality, cost of manufacturing and lead time in mind
• Communicate effectively in a team and a fast-paced environment, making well informed decisions

What we’re looking for:

• Bachelor’s degree in mechanical engineering, aerospace engineering, physics, or another relevant field
• At least 5 years of engineering design and analysis experience
• Solid background in component design and performing FEA analysis
• Experience with measurement systems, such as CMM, laser tracker, metrology and scanning tools for dimensional verification of machined components, as well as spatial measurements
• Experience with rapid prototyping and failure testing used to debug and improve designs
• Knowledge of vacuum application in areas of vacuum side welding and surface preparation/cleanliness for vacuum applications
• Experience with machine shop environment, precision machining of high strength and tough materials and development of assembly instructions
• Advanced cad skills in NX, both in modeling and drawings; understanding of GD&T and spatial tolerancing on digital measurement systems are necessary
• Familiarity with all steps in the design process with an emphasis on creativity and simplicity
• Able to communicate effectively in a team and a fast-paced environment, making well informed decisions
• Be self-motivated and exhibit excellent problem-solving skills

Bonus points:

• Familiarity with CAM process/software and G code is highly desirable. Any exposure to welding processes is a bonus
• Knowledge of vacuum application in areas of vacuum side welding and surface preparation/cleanliness for vacuum applications

Essential Requirements:

• Ability to occasionally lift up to 50 lbs
• Perform activities such as typing, standing, or sitting for extended periods of time
• 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
• Willingness to travel or work required nights/weekends/on-call occasionally
