Research and Development Engineer

PsiQuantumsmission is to build the first useful quantum computersmachines 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 approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industryincluding partners like GlobalFoundrieswe 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.

In 2024PsiQuantumannounced 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 definingand that now is the time to scale.

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 companiesincluding Lockheed Martin Mercedes-Benz Boehringer Ingelheim and Mitsubishi Chemicalto prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shiftand a path to mastering challenges that cannot besolvedany other way. The potential is enormous and we have a clearpathto make it real.

Job Summary:

Fault tolerant Quantum Computing is a transformative technology central to which is the development of single-photon and photon-number resolving detectors. We are seeking individuals with deep expertise in understanding characterizing and designing superconducting thin films. The applicant will use their expertise of superconducting thin films to perform analysis plan experiments and collaborate between fabrication characterization and modeling teams to demonstrate high efficiency photon detectors.

Responsibilities:

• Performing data analysis at scale using models involving microscopic superconductivity.
• Implementing scalable analysis methods for large-scale deployment.
• Planning co-ordinating and executing experiments to diagnose the properties of films to understand device physics and optimize fabrication processes.
• Designing superconducting single-photon detectors using comprehensive electrothermal models.
• Collaborating with theoretical numerical and data infrastructure personnel to optimize detector performance.

Experience/Qualifications:

• Demonstrated ability to systematically and rigorously analyze data from thin-film characterization techniques and to perform integrated analysis that connects thin-film materials data with superconducting device performance data.
• A strong foundation in condensed matter physics. Familiarity with BardeenCooperSchrieffer (BCS) theory and/or GinzburgLandau (GL) theory is highly desirable particularly to enable effective collaboration with superconducting theorists.
• Some hands-on experience with characterization techniques such as Electron Energy Loss Spectroscopy (EELS) Transmission Electron Microscopy (TEM) X-ray Diffraction (XRD) and cryogenic Scanning Tunneling Microscopy (cryo-STM) would be extremely valuable particularly in working closely with metrology teams.
• Experience in superconducting thin-film growth using Physical Vapor Deposition (PVD) Molecular Beam Epitaxy (MBE) or related techniques with the ability to collaborate effectively with fabrication (Fab) teams to inform process optimization and materials development.

Education

• Ph.D. in Physics Applied Physics Materials Science Electrical Engineering or a closely related field
• (Exceptional candidates with an B.S. and extensive relevant industry or research experience may be considered)
