About the role

The Manager, Cryogenic Process & Distribution Engineering is responsible for the architecture, design, and integration of the cryogenic process and distribution systems supporting PsiQuantum's global cryogenic infrastructure. This role defines the overall cryogenic system architecture, ensuring seamless integration of cryoplants, cryostats, cryogenic distribution systems, and supporting equipment.

What you'll do

• Lead the architecture and integration of complete cryogenic systems, including cryoplants, cryostats, cryogenic distribution systems, and auxiliary equipment.
• Define the overall helium and nitrogen process architecture to support all operational and maintenance modes.
• Develop process calculations, hydraulic analyses, and system performance models.
• Produce and maintain Process Flow Diagrams (PFDs), Piping & Instrumentation Diagrams (P&IDs), process descriptions, operating philosophies, and functional specifications.
• Lead HAZOPs and other process safety reviews, ensuring compliance with applicable codes and company standards.
• Define the architecture and sizing of warm and cold process piping, valves, heat exchangers, phase separators, distribution manifolds, transfer lines, and auxiliary process equipment.

What you'll need

• Master's degree or Ph.D. in Mechanical Engineering, Chemical Engineering, Cryogenic Engineering, or a related discipline (Bachelor's degree with extensive experience considered).
• 10+ years of experience designing and operating large-scale cryogenic systems involving helium and nitrogen refrigeration.
• Strong knowledge of cryogenic thermodynamics, fluid dynamics, heat transfer, and hydraulic system design.
• Demonstrated experience with cryogenic process design, PFDs, P&IDs, HAZOPs, and process safety.
• Experience integrating complex cryogenic systems including cryoplants, cryostats, and cryogenic distribution systems.
• Familiarity with process simulation tools and engineering calculation software.
