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.

What you'll do:

Lead the development and strategic execution of the operations for the ARC Remote Maintenance System
Drive the conceptual design process of the ARC fusion power plant, providing expert technical guidance for cross-functional teams
Lead the design of ARC’s radiation hardened remote handling equipment (RHE) by incorporating a mix of existing robotic technologies, custom hardware, and remotely operated heavy lift equipment
Perform expert-level maintenance assessments of the tokamak and plant to shape the development of ARC as a remotely maintainable power plant, defining processes that impact direct work and identifying/mitigating significant long-term risks
Collaborate closely with tokamak engineering teams to assist in designing the ARC tokamak for remote maintainability and finding creative and novel solutions for tokamak joints
Perform high level multi-disciplinary trade studies of solutions that involve complex and ambiguous us tradeoffs between physics, neutronics, mechanical, thermo-fluids, electrical, maintenance, materials, manufacturing, techno-economics, and other disciplines
Lead multiple teams and manage projects to solve tough multi-disciplinary problems by resolving conflicts and driving key decisions across teams
Define and own the key R&D strategy needed for the ARC remote maintenance program, and help establish/direct the plans for executing the R&D campaigns internally or with external partners
Research established and cutting-edge remote handling solutions to assess their application in the ARC remote maintenance system to influence strategic shifts and novel approaches to improve performance, reduce cost, and increase reliability
Work with external RHE/robotics organizations and general industry to manage contracted work, collaborate on cutting edge R&D, and transfer knowledge and expertise into CFS
Establish CFS’s remote maintenance design principles for RHE, the Tokamak, and plant, while propagating best practices and actively taking ownership of the growth and development of junior and peer engineers

What we’re looking for:

Structural, Mechanical, or Aerospace Engineering B.S
At least 10 years of mechanical engineering experience in the design, fabrication, testing, operations, integration, and commissioning of complex mechanical structures (e.g. fusion, fission, aerospace, marine)
At least 10 years of technical experience in the design of remote handling equipment (RHE) using robotics or remotely operated precision mechanical structures (e.g. remote welding/cutting, manipulation, alignment, rescue, inspections)
Proven track record of driving R&D campaigns of novel technology to increase TRL and unlock new design solutions in remote maintenance fields such as remote welding/cutting, inspections, bolting, manipulation, alignment, sensing, mechatronics, rad hard, and cleanliness
Deep expertise with standard actuation, guidance mechanisms, sensing, and structural mechanisms
Expertise in structural analysis via both hand calcs and finite element analysis (Ansys preferred)
Familiar with CAD, (NX preferred)
Ability to effectively lead a multidisciplinary team of engineers, scientists, technical staff, executives, and others
Ability to clearly communicate highly complex concepts to diverse audiences and build consensus
Safety conscious

Bonus points for:

Structural, Mechanical, or Aerospace Engineering M.S

Experience operating with near-complete independence to drive conceptual design of complex systems involving high level, multi-disciplinary trade studies of both RHE and machine design (e.g. tokamak, fission core, sub-sea hardware, aerospace)

Experience with the implementation of radiation hardened equipment and methods into RHE design

Experience with mechatronics or applied robotics

Experience with rescue or decommissioning RHE

Experience with site layout design of remotely operated facilities

Experience with activated waste handling (volume reduction, casking)

Experience with remote cleanliness methods for UHV environments

Experience with industrial maintenance facility layout

Familiarity with basics of sensing, high power, controls, and fluid systems

Familiarity with ultra high vacuum processes

Experience with fault tree analysis or fault management and recovery for complex integrated systems

Knowledge of fabrication methods such as welding and machining

Knowledge of engineering materials basics for metals and composites

Proficient in CAD (NX preferred)

Self-driven and autonomous, capable of managing ambiguous assignments with loosely-defined outcomes

Aptitude to use data to drive decisions

Familiarity and experience with end-to-end processes with an emphasis on creativity and simplicity

The ability to thrive in fast-paced, dynamic environments

Must-have Requirements:

Perform activities such as typing and 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

Willingness to travel or work required nights/weekends/on-call occasionally. Travel expected up to 15%

#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.
