About the role
- PsiQuantum is seeking a highly skilled Senior Cryostat Equipment Engineer to lead the installation, commissioning, and ongoing operation of advanced cryogenic and ultra-high vacuum (UHV) systems supporting quantum computing hardware.
- This role is critical to ensuring reliable ultra-low-temperature and high-vacuum environments required for quantum device performance.
Responsibilities
- Lead installation and integration of cryostats and associated subsystems, including vacuum chambers, pumps, valves, and instrumentation.
- Develop and maintain standard operating procedures (SOPs) for cryostat and vacuum system operation.
- Monitor and optimize vacuum performance (pressure levels, leak rates, outgassing) alongside cryogenic thermal stability.
- Perform helium leak detection, residual gas analysis (RGA), and vacuum diagnostics.
- Collaborate with cross-functional teams to integrate vacuum and cryogenic systems with quantum hardware.
- Perform preventive and corrective maintenance on cryostats, vacuum systems, and supporting infrastructure.
- Maintain detailed documentation, logs, and test reports for vacuum and cryogenic systems.
Requirements
- 3+ years of hands-on experience with cryogenic and/or high or ultra-high vacuum systems.
- Strong understanding of vacuum technology (UHV practices, pumping systems, sealing methods, materials compatibility).
- Experience with vacuum pumps (turbo, cryo, roughing), gauges, and leak detection methods.
- Experience installing and commissioning complex mechanical and vacuum systems.
- Ability to read and interpret engineering drawings, vacuum schematics, and P&IDs.
- Solid foundation in thermodynamics and heat transfer.
- Strong troubleshooting and problem-solving skills in lab or manufacturing environments.
Nice to have
- Bachelor's degree in Mechanical Engineering, Physics, or a related field (advanced degree preferred).
