PSI Quantum
Job Summary
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 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! Responsibilities
Lead Quantum Simulation Team : Manage, mentor, and develop a team of engineers and computational scientists working on simulations of quantum architectures spanning linear optics through to quantum error correction. Set Technical Direction : Define and execute the simulation roadmap in alignment with company priorities, coordinating with architecture, hardware, and software groups. Architect Simulation Infrastructure : Oversee the design, implementation, and optimization of internal simulation tools and frameworks to model large‑scale quantum systems efficiently and accurately. Integrate Across the Stack : Ensure interoperability between simulation tools, data pipelines, and system models spanning photonic devices, error correction, and full‑stack architectures. Strategic Collaboration : Work closely with technical leads across Quantum Architecture, System Architecture, and Software teams to ensure alignment. Operational Excellence : Establish and maintain high standards for software development practices, including version control, testing, CI/CD, and reproducible research workflows. Experience and Qualifications
Graduate level degree in Physics, Quantum Information Science, Computer Science, or a closely related discipline. Deep understanding of fault‑tolerant quantum computing architectures. 10+ years of experience in computational physics, quantum simulation, or large‑scale scientific computing, with at least 5 years in a technical leadership or management role. Proven experience leading multidisciplinary technical teams and coordinating across departments in a complex R&D environment. Strong background in numerical modeling and simulation techniques, such as Monte Carlo or tensor networks.
