Fusion Energy Base
Overview
About Commonwealth Fusion Systems: Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy. We’re designing and building commercially viable fusion power plants and working with policymakers and suppliers to build the energy industry of the future. Since 2018, we’ve raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world. We’re looking for more thinkers, doers, builders, and makers to join us. 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 cryoplant (CRYP) rejects the heat to the SPARC cooling water system. 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. What you’ll do
Provide daily on-site management of the CRYD mechanical install contractor. Review and generate complex install operation plans and procedures, oversee complex physical install work daily to respond to questions, troubleshoot issues, and ensure correctness of the work. Examples of past issues resolved include misalignment of blowdown tank riser trunions, VJL inner pipe support detachments, basement interference with turnaround tool, VJLturnaround tool o-ring extrusion, LN2 skid insulation, and bypass skid interface switch evaluation. Plan and execute CRYD mechanical install work (e.g. flange assemblies, tubing, insulation) to reduce schedule risk and contractor cost. Examples include blowdown tank top head blind flange and at-grade flange installs. Manage CRYD I&C install (control cabinets, instrumentation panels/flanges, probe assemblies and wire harnesses) through daily oversight and resolution of issues. Examples include CRYD cabinet modification to address wiring space issues. Plan and execute on-site functional testing. Example: solenoid valve assembly test. Manage last CRYD procurements (e.g. LHe offload cart, CRYD warm low pressure skid) through troubleshooting issues and guiding key decisions; travel to supplier sites to catalyze progress and prevent witness point delays; generate, review, and witness supplier test plans. Plan and execute CRYD pre-commissioning tasks (engineering support of I&C loop checks; cycling of valves; verify pressure and temperature transducers; test relief valves). Plan and execute CRYD commissioning tasks (leak checks at MAWP; demonstration of flow, pressure, temperature controls; PLC command/control; helium pump-and-purge to achieve purity; LN2 shield flow testing; warm gas circulation). Plan and execute CRYPCRYD commissioning tasks (demonstrate CRYD performance for SPARC operating modes; measure helium leakage; measure CRYD heat loads and hydraulic performance; integrate key interfacing systems). Identify, communicate, and manage key CRYD System risks. Develop derisking strategies, document decisions and learnings, and support SPARC, CRYO, and CRYD team objectives. Maintain versatility and broad understanding of CRYO and CRYD programs. Provide actionable feedback, support other CRYO priorities as necessary. Comply with CFS design control processes, document design developments, and submit design development files into M-Files. What we’re looking for
Bachelors in Mechanical, Chemical, Thermal or Process Engineering 2+ years of experience in the engineering of large-scale, integrated thermofluid systems from conceptual design through field commissioning Experience developing specifications for thermofluid components (e.g. blowers, tanks, control valves) Experience traveling to manage vendors at their sites, willing to travel occasionally Experience using engineering analysis tools: ANSYS, COMSOL, 1D compressible flow code, MATLAB, Simulink Knowledge of ASME BPVC, ASME B31.3, NFPA 70E and ASTM Standards Proficiency with a CAD software system (e.g. NX, CREO, AVEVA) Experience with safety systems and protocols (LOTO, Confined Space, Fall Protection, JHA, MSDS, PPE) Must-have requirements
Ability to occasionally lift up to 50 lbs Perform activities such as typing, standing, or sitting for extended periods 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 #LI-Hybrid Salary : $70,000 - $120,000 a year Salary range for this full-time position + equity + benefits. The actual salary will depend on level, location, qualifications, and experience. Benefits include: •
Competitive compensation with equity •
12.5 Company-wide Holidays •
Flexible vacation days •
10 sick days •
Generous parental leave policy •
Health, dental, and vision insurance •
401(k) with employer matching •
Professional growth opportunities •
Team-building activities At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. 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 (export control laws). Any offer of employment will be contingent on compliance with such laws.
