About the role

The Senior Cryogenic System Engineer is responsible for the design, analysis, verification, validation, integration, and operational support of cryogenic systems that enable quantum computing infrastructure. The role focuses on system integration of cryostats, cryogenic distribution systems, cryoplants, and related technologies, applying engineering principles across thermodynamics, heat transfer, fluid mechanics, and structural mechanics.

What you'll do

• Lead the integration of cryostat components, mechanical hardware, sensors, valves, instrumentation, and associated vacuum systems.
• Lead the integration of cryogenic equipment, including cryostats, cryogenic distribution systems, cryoplants, and cryogenic storage.
• Apply thermodynamics, heat transfer, fluid mechanics, and structural mechanics to develop, analyze, and test cryogenic system designs.
• Coordinate technical activities across multiple disciplines and provide hands-on guidance during fabrication, installation, integration, and operations.
• Lead the development of verification and validation test plans for cryogenic mechanical systems and evaluate test results.
• Select, support, and direct vendors during design, manufacturing, and testing, and resolve field issues related to cryogenic design.

What you'll need

• B.Sc., M.Sc., or Ph.D. in Mechanical Engineering, Aerospace Engineering, Physics, or a related discipline.
• 3–5+ years of experience applying engineering principles to solve complex problems related to thermal-fluid systems and/or cryogenics.
• Experience with cryogenic mechanical systems, including cryostats, cryogenic distribution systems, valve boxes, and/or cryoplants.
• Experience with requirements management, materials and component selection, FMEA, tolerance analysis, and test planning.

Nice to have

• Experience with software tools such as Mathcad, SINDA/FLUINT, Thermal Desktop, SINAPS, ANSYS APDL, ANSYS Workbench, SolidWorks, SpaceClaim, LabVIEW, and MATLAB.
• Experience working with cryocoolers and vacuum pumps.
• Experience coordinating technical activities during construction, installation, or commissioning of large-scale scientific or industrial facilities.
• Knowledge of material performance, design constraints, and manufacturing constraints under cryogenic conditions.
• Hands-on experience with fabrication methods such as machining, welding, brazing, soldering, and forming, as well as lab testing and data acquisition.
• Understanding of Geometric Dimensioning & Tolerancing per ASME Y14.5.
