Process Engineer

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy. CFS collaborates with MIT to leverage decades of research combined with groundbreaking new high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost. Our mission is to deploy these power plants to meet global decarbonization goals as fast as possible. To that end, CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. To implement this plan, we are looking to add dedicated people to the team who treat people well, improve our work by adding multifaceted perspectives and new ways of solving problems, have achieved outstanding results through a range of pursuits, and have skills and experience related to this role.

ARC will be the first machine to produce electricity from fusion energy, serving as the cornerstone to a new industry. ARC will strongly leverage the work that’s been done for SPARC in developing HTS magnets and other key tokamak systems. However, because of its mission to deliver power to the grid, the ARC tokamak has a few systems not included on SPARC, such as the Blanket System, which uses FLiBe to breed tritium and capture heat. The Blanket System group within R&D is a growing team that is delivering key scientific and engineering results to push the technical readiness level of these new enabling technologies higher. The Blanket System team at CFS is looking to grow the team as we expand our operations into larger-scale, FLiBe-based test loops. These test loops will operate in a novel and extreme environment, with high temperatures, chemical hazards, and new materials. We are looking for a Process Engineer to develop the technical basis for these loops. This engineer needs to be a creative, proactive problem solver who can work with the rest of the Blanket System team to tackle first-of-a-kind engineering systems (e.g. hydrogen extraction from FLiBe). The Blanket System team has a strong practice of carrying engineering risk where appropriate while attentively and aggressively managing safety risk, and we are looking for an engineer who will actively contribute to this culture. 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. This team member will:

• Develop and maintain specifications and interface requirements for the design, fabrication, and operation of salt systems, soliciting feedback from interfacing teams as necessary
• Identify, communicate, and manage design risks. Develop efficient de-risking strategies and plans
• Support hazard identification and risk assessment (HIRA) activities (e.g. HAZOP, LOPA, What If?)
• Perform design calculations (e.g. H&MB) and develop technical deliverables (e.g. PFD, P&ID, Process Design Basis, Control Philosophy, Operation & Maintenance Strategy), to specify various salt systems during all operating modes
• Travel as necessary to vendor sites
• Provide component specifications and oversee vendor selection process
• Develop and execute installation and commissioning plans and procedures, manage installation and supporting teams, and work hands-on as necessary
• Work closely with other CFS teams including:
• – Safety team to manage chemical hazards (including beryllium) in existing and new experimental facilities
• – Other R&D functions including Mechanical, I&C etc
• – Supply Chain Team
• – ARC Design Team

The ideal candidate will have most, if not all, of these requirements:

• BS in Chemical, Mechanical, Petroleum or Nuclear Engineering or a related field
• 5+ years of experience in the engineering of integrated thermofluid and chemical processing systems, from conceptual design through operation
• Experience developing specifications for thermofluid components, e.g. pumps, valves, tanks, etc
• Ability to work effectively in a multidisciplinary team of engineers, scientists, technical staff and others
• Ability to clearly express and critique ideas
• Great communication and organizational skills (required)
• Strong problem solving skills, ability to approach new problems with creativity
• Working knowledge of PIP, ASME BPVC, ASME B31 and other relevant industry standards
• Working knowledge of process and fluid simulation tools (COMSOL, Aspen, etc.) and/or scientific programming languages (Python, Matlab, etc.)

Additional preferred experience and/or qualifications:

• Experience traveling to manage vendors at their sites, willing to travel occasionally
• Experience with molten salt or high temperature systems
• Experience with degassing systems
• Experience with industrial gas/liquid and liquid/liquid separation systems
• Experience with Front-End-Loading (FEL) engineering design cycle
• Experience with first-of-a-kind, R&D, or pilot system development
• Work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, high current, pressure systems, and cryogenics
• Willingness to travel or work required nights/weekends/on-call occasionally

CFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits. We all tightly align with our company values of integrity, execution, impact and self-critique. As we grow, we are looking to add talented people who are mission driven and bring diverse perspectives and new ways of solving problems. At CFS, we deeply value diversity and are an equal opportunity employer by choice. We consider all qualified applicants equally for employment.
