Originally posted 11 May 2026 by the employer. Relisted by the employer on 30 July 2026.
About the role
PsiQuantum is seeking a Cryostat Equipment Engineer to lead the installation, commissioning, and ongoing maintenance of advanced cryogenic systems supporting quantum computing hardware. This role ensures the reliable operation of large-scale cryostats and associated vacuum and instrumentation systems across R&D and production environments.
What you'll do
- 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. - Monitor cryostat performance, diagnose faults, and perform preventative and corrective maintenance. - Interface with instrumentation systems such as temperature sensors, pressure transducers, flow controllers, and data acquisition systems. - Ensure compliance with safety standards related to cryogens, vacuum systems, and high-voltage equipment while maintaining detailed technical documentation.
What you'll need
- 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, such as dilution refrigerators, liquid helium systems, or closed-cycle cryocoolers. - Experience with instrumentation and data acquisition systems, along with root-cause analysis skills. - Ability to read and interpret engineering drawings, P&IDs, and electrical schematics.
Nice to have
- Experience working with cryostats in quantum computing, superconducting systems, or low-temperature physics environments. - Knowledge of vacuum system design, leak detection via helium mass spectrometry, and materials compatibility. - Familiarity with control systems such as PLCs, LabVIEW, or similar platforms. - Experience in a cleanroom or semiconductor environment. - Advanced degree in a relevant field.
Skills: Cryostat, quantum computing, high-vacuum systems, commissioning, maintenance
