## 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 Staff Mechanical Engineer - Remote Maintenance**

 

CFS is designing ARC as the world’s first commercial fusion power plant with the goal of bringing reliable and clean fusion energy to the grid. Due to device activation and commercial uptime needs, ARC will need periodic, fast, and reliable maintenance to be performed fully remotely. This will require novel solutions and integration in the fields of robotics, remote handling equipment (RHE), plant layout, manufacturing, and tokamak design. ARC’s Remote Maintenance System will thus be a critical aspect of realizing CFS’s mission to deliver the urgent transition to fusion energy.

 

The Remote Maintenance team is responsible for designing ARC’s Remote Maintenance System. As a Staff Remote Maintenance Engineer on the team, you will develop ARC’s maintenance scheme by designing RHE and collaborating with tokamak and plant engineering teams in the design of a maintainable power plant. You will play a key role in ARC’s pre-conceptual design phase along with other teams and navigate complex multi-disciplinary problems involving physics, neutronics, thermo-fluids, structures, maintenance, manufacturing, assembly, techno-economics, and other disciplines. This role also requires proactive R&D in novel remote maintenance technologies.

#LI-Hybrid

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.**
