PsiQuantum’s 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 architecture and approach is based on silicon photonics. By leveraging the 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: photons don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale.

PsiQuantum also 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—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.

Job Summary:

PsiQuantum is opening a new laboratory in Brisbane, Australia, to focus on the validation and high-performance operation—and related methodology—of our quantum photonic systems. We are looking for a motivated technical engineer to support these experimental efforts and development within the laboratory. The successful candidate will be responsible for managing installation and maintenance of complex subsystems, and some operations elements as we bring up and operate the laboratory. They will work with measurement, design, and operations teams in Brisbane and across all of PsiQuantum’s technical disciplines.

We are seeking an individual with a broad range of practical skills and experience across some/all of our technology areas which include: cryogenics, vacuum, electrical, electronics, controls, optics and mechanical. There will be opportunities to upskill in some areas where candidates have less experience.

This role will be based onsite in Brisbane, Australia. However, PsiQuantum is a highly collaborative international organization, and we expect this individual will travel up to 20% of their time outside Australia as required.

Responsibilities:

Operation of high-end lab equipment including cryostats, vacuum systems, vacuum pumps, hand tools etc.
Support testing and characterization of RF components at cryogenic temperatures.
Assemble and maintain cryogenic setups including cryostats, vacuum pumps, and control equipment.
Electro-optic experiment assembly, including into cryostats.
Quality Control checks and data logging.
Develop and execute and document best practice procedures.
Fault finding, repair and maintenance in lab hardware (in Australia and worldwide), including out of hours where required.
Plan maintenance and upgrades of core test equipment to ensure maximum up-time.
Supervision of interns/apprentices and contractors

Experience/Qualifications:

At least 5 years practical experience in a similar role within a scientific or advanced engineering environment.
Experience working within multidisciplinary teams.
Experience building and operating cryogenic equipment.
Vacuum equipment assembly and test.
Good understanding of rf best practice and rf signal cabling, including in cryo environment.
Experience operating test equipment manually and via control software.
Effective communication and interpersonal skills to collaborate with various teams and external stakeholders.
Problem-solving abilities and a proactive approach to identify and resolve potential issues.
Exceptional organizational skills and the ability to handle multiple tasks simultaneously, as well as taking initiative.

Preferred Skills & Experience:

Electronics assembly.
Ability to solder to a high standard General mechanical assembly and fitting.
Ability to communicate effectively with electrical and general manufacturing contractors.
Proficient in the use of computer software for hardware debug and data logging.
Experience in setting up computer/hardware networks.
Experience working on international projects involving travel to remote locations for install/maintenance.
