Cryostat Equipment Engineer

Job Summary

PsiQuantum is seeking a Cryostat Equipment Engineer to lead the installation, commissioning, and ongoing maintenance of advanced cryogenic systems supporting our quantum computing hardware.

Responsibilities

• Install and commission quantum computing cryostats, including integration with mechanical, electrical, and control subsystems.
• Operate and maintain high-vacuum systems (UHV/HPV), including pumps, gauges, valves, and leak detection equipment.
• Develop and execute commissioning procedures, acceptance tests, and system validation protocols.
• Maintain detailed documentation, including schematics, procedures, maintenance logs, and system modifications.
• Support continuous improvement efforts in system design, reliability, and operational efficiency.
• Ensure compliance with safety standards related to cryogens, vacuum systems, and high-voltage equipment.

Qualifications

• Bachelor’s degree in Mechanical Engineering, Physics, Electrical Engineering, or a related field (or equivalent experience).
• Hands-on experience with high-vacuum or ultra-high-vacuum (UHV) systems.
• Experience installing, commissioning, and maintaining complex equipment in a lab or industrial setting.
• Familiarity with cryogenic systems (e.g., dilution refrigerators, liquid helium systems, or closed-cycle cryocoolers).
• Experience with instrumentation and data acquisition systems.
• Strong troubleshooting and root-cause analysis skills.
• Ability to read and interpret engineering drawings, P&IDs, and electrical schematics.

Preferred Qualifications

• Experience working with cryostats in quantum computing, superconducting systems, or low-temperature physics environments.
• Knowledge of vacuum system design, leak detection (helium mass spectrometry), and materials compatibility.
• Familiarity with control systems (e.g., PLCs, LabVIEW, or similar platforms).
• Experience in a cleanroom or semiconductor environment.
• Advanced degree in a relevant field.
