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 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 R&D Test Engineer

We’re seeking an experienced Test Engineer to lead the testing and de-risking of our cutting-edge HTS magnet technology, playing a key role in advancing fusion energy. Embedded within our R&D organization, you’ll take on a broad range of responsibilities, from developing methodologies with magnet physicists to conducting root cause analysis alongside manufacturing experts working with complex new materials. This dynamic role demands flexibility, cross-disciplinary collaboration, and the ability to execute tests on tight timelines. You’ll lead the integration and operation of complex test stands, refine procedures, and drive continuous improvement to help achieve our extraordinary milestones in making fusion a reality.

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.

We value diversity deeply and are proud to be an equal opportunity employer by choice. We consider all qualified applicants equally, regardless of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law.

What you'll do:

Lead magnet test campaigns in cryogenic, vacuum, and high-current environments

Develop detailed test plans and ensure data integrity with robust instrumentation and control

Drive improvements to test stands, optimizing for test rate and ensuring data quality

Design, analyze, and build test equipment, including mechanical, electrical, and fluid systems

Maintain and document test requirements, risks, and safety protocols

Manage test schedules, budgets, and technical documentation (P&IDs, CAD designs, schematics, etc.)

Improve test processes for repeatability and efficiency

Analyze test data, create custom tools for data analysis, and present findings to cross-functional teams

Lead anomaly investigations and resolution, collaborating with physicists and engineers

What we’re looking for:

Bachelor’s (or higher) in engineering or applied physics, with 5+ years of hands-on testing experience

Expertise in test stand operation, data collection, and cross-functional collaboration

Strong background in test planning, data analysis, and test equipment design

Experience with electromagnetic fundamentals and troubleshooting complex systems

A passion for process improvement and innovative problem-solving

Excellent communication skills, with the ability to present technical topics clearly

Self-motivated, results-driven, and eager to learn

Willingness to travel and occasionally work nights/weekends/on-call

Bonus points:

Experience with structural FEA software, particularly ANSYS and COMSOL

Proficiency in using NX and Teamcenter for designing complex test equipment and assemblies

Experience with large-scale data collection, manipulation, and analysis to derive actionable insights

Hands-on experience operating complex test stands for long-duration test campaigns

Essential Requirements:

Ability to occasionally lift up to 50 lbs

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

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