Cryo and Electronic Test Engineer

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 center 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 fiber connectivity.

In 2024, PsiQuantum announced two government-funded projects to support the build-out of our first Quantum Data Centers 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:

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.
