About The Position

Commonwealth Fusion Systems (CFS) is seeking a Staff Mechanical Engineer specializing in Remote Maintenance to join their mission of delivering fusion energy. This role is crucial for the design and development of the ARC fusion power plant, specifically focusing on the Remote Maintenance System. The engineer will be responsible for designing remote handling equipment (RHE), collaborating with tokamak and plant engineering teams, and conducting research in novel remote maintenance technologies. This position involves navigating complex multi-disciplinary problems and contributing to the pre-conceptual design phase of ARC.

Requirements

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.
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%.

Nice To Haves

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.

Responsibilities

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 trade-offs between physics, neutronics, mechanical, thermo-fluids, electrical, maintenance, 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.
