Job description
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 we’re working with policymakers, suppliers, and many others to build the energy industry of the future.
We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world.
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 Mechanical Engineer, RF Systems
SPARC sustains fusion reactions by feeding >25MW of 120MHz RF power into the tokamak to heat the plasma to 100 million Kelvin. We need a Mechanical Engineer to design the critical physical infrastructure that routes this massive power, from coax transmission lines that span the entire plant to the intricate cooling plates required for high-power electronics.
At this level, you will own the physical design and integration of robust mechanical systems, translating requirements into manufacturing-ready hardware. You will design everything from large-scale utility interfaces and custom bellows to sheet metal parts and custom heat sinks, taking designs from ideation and CAD modeling through fabrication and direct plant integration.
For more information on the SPARC RF plant, see the SPARC journal papers here:
Overview of the SPARC tokamak
Physics basis for the ICRF system of the SPARC tokamak
What you’ll do:
Design specialized RF Heating plant components working closely with RF Engineers. These include large-diameter coaxial transmission lines and devices such as stub tuners and RF testing loads
Decompose high-level system requirements into actionable mechanical specifications, owning the mechanical designs for the RF Heating system
Collaborate daily with a dedicated CAD drafting team, providing clear guidance to detail, rigorously reviews, and releases
Partner cross-functionally with RF engineers, electronics engineers, process engineers, and other disciplines
Architect thermal management solutions by integrating complex water and air cooling loops directly into high-power electronics enclosures and plant systems
Develop large sheet metal components, precise mounting hardware for custom printed circuit board assemblies, cold plates, and more
Perform structural loads analysis and thermal analyses to ensure design viability
What we’re looking for:
Bachelor’s degree in Mechanical Engineering, Physics, or a related field
5+ years of hands-on mechanical design experience in industrial, heavy machinery, high-power electronics, electric vehicle, or aerospace environments
Demonstrated experience as the primary creator and owner of mechanical design architectures, operating as a core design engineer
Direct experience performing structural loads analysis and thermal analyses to validate mechanical designs
High proficiency in 3D CAD software and creating detailed manufacturing drawings utilizing GD&T standards
Possess a strong fundamental understanding of heat transfer, structural mechanics, and fluid dynamics
Bonus points for:
Experience using Siemens NX for 3D modeling and Teamcenter for product lifecycle management and drawing release workflows
Background decomposing complex system requirements into clear mechanical hardware specifications
Experience designing large-scale pipe routing, coaxial transmission lines, flanges, bellows, or active water and air cooling systems
Experience with complex electronics assemblies and the thermal management of such assemblies
Deep familiarity with sheet metal fabrication processes, machining capabilities, and communicating directly with contract manufacturers
Must-have Requirements:
Ability to lift up to 50lbs
Perform activities such as stooping, climbing, standing, typing or sitting for extended periods of time
Willingness to travel or work required nights/weekends/on-call occasionally
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
Salary range for this full-time position + equity + benefits.
$90,000 - $145,000 a year
Benefits include:
Competitive compensation with equity
13 Company-wide Holidays
Flexible vacation days
10 sick days
Generous parental leave policy
Health, dental, and vision insurance
401(k) with employer matching
Professional growth opportunities
Team-building activities
