About the company:

Commonwealth Fusion Systems (CFS) is on a mission to deliver clean fusion energy to the planet fast enough to matter for humanity’s biggest challenges.

It’s urgent. The gap between the energy we need and the energy we have is widening every day. Fusion is a critical part of the energy transition away from fossil fuels, a new chapter for the world’s energy supply.

We’re committing to delivering fusion power plants and a full-fledged fusion energy industry as we’ve delivered on other promises. Like the world’s strongest high-temperature superconducting magnet, the game-changing technology that’s making commercial fusion energy a reality.

We’ve raised over $2 billion in capital — more than any other fusion energy company — and attracted top talent to design, build, and deliver commercial fusion power plants. And we’re working with policymakers and suppliers to make fusion energy available globally.

As we push toward the fusion-energy future, we’ll keep setting and meeting milestones, sharing and validating our progress, and encouraging others to do the same.

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 nearly $3 billion in capital, making us the largest and leading private 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 Director of Magnet Engineering

CFS is designing SPARC, a tokamak able to achieve net energy plasmas. SPARC includes HTS and copper magnets, thermal shields, vessels and plasma facing components, all subject to large operational loads (thermal, electromagnetic, etc) and competing for space. As the Director of Magnet Engineering, you will manage the engineering staff responsible for designing and delivering our HTS Magnets to support SPARC and beyond.

15+ years of experience in the engineering of magnets or similarly complex hardware systems

Experience with developing and designing hardware systems through the use of 3D modeling and simulation software

5+ years of supervisory experience with at least 10 individuals

Experience designing for environments with extreme thermal variations

Ability to develop and manage design procedures

Familiarity with codes including ASME standards

Experience with CAD design tools such as: NX, Creo, SolidWorks, etc.

Ability to clearly express and critique ideas

Attention to detail

Emphasis on elegance and simplicity over complexity

Drive towards commercially viable solutions

Values that align with our company’s values of integrity, execution, impact, and self-critique

Bonus points for:

Experience with REBCO and high-temperature superconducting tape

Experience designing high-field magnets

Experience designing for and operating in ultra-high vacuum environments

Experience designing and operating cryogenic fluid systems

Must-have Requirements:

Perform activities such as typing, standing, or sitting for extended periods of time

Dedication to safety to mitigate hazards that may include heat, cold, noise, fumes, strong magnets, lead, high voltage, and cryogenics

Willingness to travel or work required nights/weekends/on-call occasionally
