Senior Process Engineer

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.

CFS is looking for a Senior Process Engineer with deep chemical engineering fundamentals and experience designing, scaling up, commissioning, and operating process systems in large industrial facilities.

The ideal candidate comes from an industry such as power generation, petrochemical processing, liquefied natural gas (LNG), industrial gases, chemicals, air separation, cryogenic refrigeration, pulp & paper, or another large-scale process industry. You understand how to translate fundamental process requirements into practical industrial systems and have taken designs from early concepts through Front-End Loading (FEL), detailed engineering, construction, commissioning, start-up, and operation.

Fusion power plants bring together process technologies that traditionally span multiple industries. At CFS, you will have the opportunity to work across cryogenic systems including helium and nitrogen, power generation and steam systems, molten salt systems, fueling and gas processing, vacuum systems, and process utilities such as cooling water and instrument air.

We are looking for an engineer who understands how these systems behave in the real world because they have personally designed, built, commissioned, operated, or troubleshot industrial process equipment. You should be equally comfortable developing a process design basis, building a heat and material balance, sizing equipment, originating and owning P&IDs, leading a HAZOP, walking down installed piping, supporting start-up, and diagnosing why an operating system is not performing as designed.

• Own process engineering scope for complex systems from early concept through design, construction, commissioning, start-up, and operation
• Develop process concepts and translate fundamental engineering requirements into practical, commercially viable industrial systems
• Develop process design bases, operating envelopes, design cases, process flow diagrams (PFDs), heat and material balances, utility balances, P&IDs, equipment lists, line lists, and process datasheets
• Apply chemical engineering fundamentals including thermodynamics, phase equilibrium, fluid mechanics, heat and mass transfer, transport phenomena, reaction engineering, separations, process dynamics, and process control
• Develop steady-state and dynamic process models and use engineering analysis to guide system architecture, equipment selection, and operating strategy
• Size and specify process equipment including pumps, compressors, blowers, heat exchangers, vessels, columns, piping systems, control valves, relief devices, and other unit operations
• Lead process engineering through Front-End Loading (FEL) and progressively mature systems from conceptual design through process definition and engineering definition
• Evaluate process alternatives and technical tradeoffs considering performance, safety, reliability, operability, maintainability, capital cost, and lifecycle cost
• Develop equipment…
