Repository/DevOps Engineer

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: Quantum computing promises to solve many important problems that could never be solved on any conventional computer. At PsiQuantum we’re building a general-purpose silicon photonic quantum computer to tackle these very problems. PsiQuantum is looking for an experienced and highly motivated DevOps engineer who can architect and optimize large scale research & development repositories utilised in a range of applications in the design/build/validation process for photonic chip design and tape out. Quantum computing requires breakthrough engineering innovations; we expect a software platform that integrates many industry standard components with novel and custom software designed to be automated, reduce errors and scaled. Being a startup in an all-new engineering field, the role is expected to be highly collaborative and requires excellent technical skills to execute projects to meet milestones and technical scope. An ideal DevOps Engineer is a hands-on automation expert who designs, builds, and maintains scalable, secure, and reliable software delivery pipelines. They possess deep experience with Git-based repository management (branching strategies, code reviews, access controls), CI/CD platforms, and Infrastructure as Code tools. The ideal candidate understands containerization and orchestration, artifact management, dependency governance, and secure supply chain practices. They proactively improve developer experience by reducing build times, increasing deployment frequency, and implementing robust testing and rollback strategies. Strong Python skills, cloud platform expertise and observability knowledge are essential. Beyond technical ability, they demonstrate ownership, clear communication, and a continuous improvement mindset, collaborating closely with development, security, and operations teams to deliver resilient, compliant, and high-performing release workflows. Responsibilities: Repository Management: Architect, Consolidate, Configure and maintain repository security, access controls, branch
