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 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 a Manufacturing Engineer

We are looking for a hands-on Manufacturing Engineer to captain our weekend operations. You will be the technical anchor for the "5th Shift," ensuring that our production of high-temperature superconducting magnets continues safely and efficiently when the weekday engineering team is offline.

This role requires someone who can lead through influence, make sound decisions under pressure, and bring clarity to ambiguity in a fast-moving, First-of-a-Kind (FOAK) manufacturing environment.

You will set the tone for the weekend team which will include keeping technicians focused, engaged, and operating at a high level while turning first-time challenges into scalable, repeatable processes.

This is a First-of-a-Kind (FOAK) manufacturing environment. We are designing the product while building the machine. Your job is to bring order to that chaos, turning "first encounters" with novel problems into standardized, repeatable processes.

The Schedule:

Shift: Friday through Sunday, 6:00 pm - 6:00 am

Salary Range: $103,000 - 166,000 (includes 15% shift differential)

#LI-Onsite

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.

This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, “Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.
