About the Job

Requirements

  • A Master's degree or Ph.D. in Mechanical Engineering, Chemical Engineering, Cryogenic Engineering, or a related discipline is required; a Bachelor's degree with extensive experience is also considered.
  • At least 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, Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), HAZOPs, and process safety.
  • Experience integrating complex cryogenic systems, including cryoplants, cryostats, and cryogenic distribution systems.
  • Experience working with Engineering, Procurement, and Construction (EPC) contractors and cryogenic equipment manufacturers.
  • Familiarity with process simulation tools and engineering calculation software.
  • Willingness to travel internationally to support manufacturing, installation, commissioning, and operations.

Responsibilities

  • 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 and 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.
  • Specify process equipment and prepare technical specifications for procurement.
  • Support vendor selection, technical reviews, manufacturing follow-up, factory acceptance testing (FAT), and site acceptance testing (SAT).
  • Support installation, pre-commissioning, commissioning, performance testing, and operation of cryogenic systems.
  • Troubleshoot system performance and lead continuous improvements to process efficiency, reliability, and operability.
  • Establish engineering standards, design guidelines, and best practices for cryogenic process and distribution engineering.
  • Lead and mentor the Cryogenic Process and Distribution Engineering Team while fostering technical excellence and knowledge sharing.
  • Collaborate closely with Process Controls, Cryostat, Cryoplant, Facilities, Operations, System Engineering, and external suppliers to ensure successful project execution across multiple global sites.

About the Company

PsiQuantum

Utility-scale fault-tolerant photonic quantum computers

PsiQuantum builds quantum computers for utility-scale use, using photons as qubits and a semiconductor-friendly Omega chipset. The Omega platform combines high-performance single-photon sources, superconducting detectors, and optical switches to enable scalable chip-to-chip interconnects and precise quantum operations. It explores fault-tolerant methods like fusion-based quantum computation (FBQC) to improve error correction and resilience, targeting applications in chemistry, materials science, optimization, and cryptography. The company stands out by emphasizing manufacturability with standard semiconductor processes, large-scale chip integration, and collaborations with government and research institutions to push toward a practical, widely accessible quantum computer.
