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:
Superconducting nanowire single photon detectors (SNSPD) are a key technology that are mandatory for the development of photonic quantum computers. The job will involve large-scale analysis of SNSPD data and film metrology and design of experiments informed by microscopic superconductivity theory to make improvements to SNSPD devices and materials. The job would involve close interaction with multiple teams spanning material science, fabrication ,testing and layout to deploy SNSPD’s at scale for the development of fault-tolerant quantum computers.
Responsibilities:
The role will require large-scale analysis of SNSPD data based on a deep understanding of SNSPD physics, spanning microscopic theories of superconductivity as well as phenomenological models suitable for devices. The analyzed data will be used to deploy future material design and device design tape-outs for scalable, high performance and high temperature operation.
Experience/Qualifications:
>5 years experience in the design and development of SNSPDs , or in adjacent areas involving microscopic theory of superconductivity or condensed matter physics or superconducting device design. A PhD in a technical discipline is preferred but not necessary.
PsiQuantum provides equal employment opportunity for all applicants and employees.

Skills Required
- More than 5 years of experience designing and developing SNSPDs, or in adjacent areas involving microscopic superconductivity theory, condensed matter physics, or superconducting device design.
- PhD in a technical discipline.
What We Do
Quantum computing will be a world-changing technology with the potential to unlock powerful advances in medicine, energy, finance and beyond. At PsiQuantum, we’re focused on building the world’s first useful quantum computer. A useful quantum computer requires at least 1,000,000 qubits and error correction. We believe photonics is the only path to building a useful quantum computer. Our team at PsiQuantum is a mix of quantum physicists, semiconductor, systems, and software engineers, system architects and more. Error correction is at the centre of everything we do; and we focus on solving real-world problems. If you’re interested in joining our team, we are always open to hearing from exceptional people interested in working on one of the defining technologies of our lifetime.
