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 working with policymakers and suppliers to build the energy industry of the future. We're in the best position to make it happen. Since 2018, we've raised nearly $3 billion in capital, making us the largest and leading private 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 Cryogenic Engineer. The SPARC facility is intended to be the world's first net-energy fusion device. It features a 30kW at 10K equivalent cryogenics (CRYO) plant to provide cooling to high-temperature superconducting (HTS magnets) and other critical components within the reactor. Within CRYO, the cryodistribution (CRYD) system consists of a 30-ft distribution box and up to 30” outer diameter vacuum-jacketed lines to remove and convey heat generated within the reactor to the cryoplant (CRYP). The CRYD System enables direct delivery, storage, release, recapture, and recool of cryogenic helium at large flow rates through the HTS magnets during the highest power fusion pulses. The system consists of a distribution box, series of large cryogenic tanks, valves, and VJLs, with a dedicated controls system. The CRYD Cryogenic Engineer will be responsible for delivery of final, minor procurements, and completion of key aspects of the final three months of system install, as well as multiple months of functional testing and commissioning of the SPARC CRYD System in order to meet technical requirements, on-time and on-budget.
