Manager, Cryogenics Process Control

PsiQuantums mission is to build the first useful quantum computers: machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016 our singular focus has been to build and deploy million-qubit fault-tolerant quantum systems.

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy pharmaceuticals finance agriculture transportation materials and other foundational industries.

Our architectureand approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industry including partners like GlobalFoundries we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photonsdontfeel heat are immune to electromagnetic interference and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

That approach has since been tested at the highest level of scrutiny the U.S. government applies to emerging technology and it has held 2025PsiQuantumclosed a$1 billionfunding round that valued the company at$7 2026 the U.S. Department of Commerce signed a $100 million Letter of Intent under the CHIPS and Science Act followed by a $125 million agreement with DARPA under Stage C of its Quantum Benchmarking InitiativePsiQuantumsmost valuable U.S. government agreement to date. This year we also broke ground on our utility-scale quantum computer in Brisbane Australia and continued building out our Chicago site. Victor Peng our CEO and co-founder Jeremy OBrien now ExecutiveChairman lead a team and board that reflects how seriously the world is taking this build joined this year by Intels Lip-Bu Tan and Atomicos NiklasZennström.

PsiQuantumalso develops the algorithms and software needed to make these systems commercially valuable. Our application software and industry teams work directly with leading Fortune 500 companies includingAirbusLockheedMartin Mercedes-Benz Boehringer Ingelheim and Mitsubishi Chemical to prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shift and a path to mastering challenges that cannot besolvedany other way. The potential is enormous and we now havethe fundingthe governmentvalidation andthe sitesunder construction to make it real.

Job Summary:

The Manager Process Control Engineer is responsible for the design implementation commissioning and operation of the instrumentation electrical and control systems supporting PsiQuantums cryogenic infrastructure including cryoplants cryostats and cryogenic distribution systems.

In addition to technical ownership the Manager Process Control Engineering will build and mentor the PsiQuantum Cryogenics Controls team establishing best practices in instrumentation automation PLC programming and system operation.

PsiQuantum designs installs commissions and operates cryogenic infrastructure across multiple locations worldwide. This position is based in Milpitas California with travel required to support global installations and operations.

Responsibilities:

• Lead the design implementation and commissioning of PLC-based cryogenic control system including control architecture P&IDs control narratives control logic alarms and safety interlocks.
• Serve as the electrical engineering lead for the cryogenic system with responsibility for electrical systems up 24 to 480 V and coordination with external specialists for higher-voltage installations.
• Design specify install and commission instrumentation control panels PLC cabinets field wiring UPS systems motors VFDs electrical heaters and associated power distribution.
• Define the controls hardware architecture including instrumentation PLCs remote I/O industrial networks communications and system integration.
• Select instrumentation and controls hardware work closely with equipment vendors participate in design reviews and Factory Acceptance Tests (FAT) and ensure third-party equipment complies with PsiQuantum standards.
• Collaborate with Cryogenic Engineers to develop control philosophies operating sequences and control narratives for all cryogenic equipment.
• Develop the PLC software based on the control philosophy; develop and test control logic safety interlocks and automation functions.
• Develop Human-Machine Interface (HMI) applications to provide intuitive operation diagnostics trending and alarm management.
• Lead installation loop checks I/O verification bench testing commissioning startup and performance validation of new cryogenic systems.
• Develop systems for data acquisition historian integration trending diagnostics and performance analytics to support optimization troubleshooting and root-cause analysis.
• Troubleshoot complex instrumentation electrical and automation issues during commissioning and plant operations.
• Provide day-to-day hand-on technical leadership for Process Controls engineers and technicians by assigning work setting priorities mentoring team members reviewing designs and supporting professional development.
• Support cryogenic operations by participating in incident investigations system upgrades reliability improvements and on-call technical support when required

Experience/Qualifications:

• Bachelors or Masters degree in Electrical Engineering Controls Engineering Chemical Engineering or a related engineering discipline.
• 710 years of experience designing and commissioning industrial process control systems.
