Quantum computing holds the promise of humanity’s mastery over the natural world, but only if we can build a
real
quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world‑changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data centre footprint.
By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.
PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier‑1 semiconductor fabs such as GlobalFoundries where we leverage high‑volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don’t feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fibre connectivity.
In 2024, PsiQuantum announced two government‑funded projects to support the build‑out of our first Quantum Data Centres and utility‑scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing’s potential impact and the need to scale this technology to unlock that potential. And we won’t just be building the hardware, but also the fault tolerant quantum applications that will provide industry‑transforming results.
Quantum computing is not just an evolution of the decades‑old advancement in compute power. It provides the key to mastering our future, not merely discovering it. The potential is enormous, and we have the plan to make it real. Come join us.
There’s much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!
Job Summary We are seeking a day shift
Equipment Maintenance Engineer
to support and sustain critical laboratory and production equipment including
test instrumentation, vacuum chambers, and cryogenic systems . This role ensures high equipment uptime, reliability, and performance through proactive maintenance, troubleshooting, and repair. The successful candidate will partner closely with test,
R&D , and operations teams to enable safe, efficient, and uninterrupted program execution.
Responsibilities
Perform preventive and corrective maintenance on vacuum systems, cryogenic equipment, and complex test infrastructure.
Troubleshoot electrical, mechanical, and controls issues to minimise downtime.
Develop and execute maintenance schedules, calibration plans, and system upgrades.
Maintain detailed documentation of equipment status, service activities, and repair history.
Support equipment installation, commissioning, and validation activities.
Monitor system performance, recommend improvements, and implement reliability enhancements.
Ensure compliance with safety standards, facility protocols, and regulatory requirements for pressurised, high‑vacuum, and cryogenic systems.
Provide technical support and training to engineering and operations staff on safe and proper use of equipment.
Collaborate with vendors and contractors for specialised repairs and component sourcing.
Contribute to continuous improvement of maintenance procedures, spare parts strategies, and failure analysis.
Experience/Qualifications
Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or related discipline (or equivalent technical experience).
3+ years of hands‑on experience maintaining complex laboratory or industrial equipment.
Knowledge of vacuum technology (pumps, seals, gauges, leak detection).
Familiarity with cryogenic systems (LN2, LHe, cold heads, compressors).
Strong troubleshooting skills in mechanical, electrical, and control systems.
Ability to read technical drawings, schematics, and service manuals.
Excellent organisational and documentation skills.
Strong commitment to safety in high‑risk equipment environments.
Must be able to lift 50 lbs.
Experience in aerospace, semiconductor, or research lab environments.
PLC and instrumentation controls troubleshooting.
Root cause analysis and reliability engineering methods.
Preventive maintenance programme development.
Experience with fibre optics, lasers and optical assemblies.
Hands‑on equipment experience with hand tools and machine shop tooling expertise.
Proficient in Word, Excel, PowerPoint, Outlook, Visio.
Strong analytical and problem‑solving skills combined with a strong technical presence.
Good understanding of mechanical design concepts and machinery: Electrical, Mechanical, and Electromechanical schematics, motors, pumps, vacuum, and hydraulics.
