PsiQuantum

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. Come join us. Job Summary: Our system architecture team sits at the interface of hardware development, manufacturing, and the quantum architecture to design the first fault-tolerant quantum computer. We are looking for a hands-on technical manager to lead the validation and closure of quantum architectural models against hardware system data - a vital activity in our progress towards this goal. Responsibilities: Lead and actively contribute to projects related to the development of quantum optical system models and their closure against real quantum computing system data. Manage and grow a team of architects providing real-time analysis and feedback to engineering teams regarding quantum hardware behavior. Co-ordinate closely with photonics, electronics, systems and architecture teams to ensure consistent, data-driven descriptions of system architecture and performance are available. Experience/Qualifications: PhD in quantum physics discipline, quantum optics and photonics preferred. 5+ years of relevant academic or industry research experience in quantum computing or quantum information. Knowledge of linear optical quantum computing and its associated error models required. Experience performing or working in close collaboration with quantum optics experiments required. Ability to work across domains and collaborate effectively with multi-disciplinary technical teams across sites & timezones. Experience programming in Python and competent use of collaborative software development tools (e.g., GitHub) is desirable.
