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: We are seeking a Senior Optical Fibre Engineer to develop and evaluate advanced optical fibre for high-performance optical systems. This role combines optical modelling, deep understanding of advanced speciality optical fibre behaviour and design tradeoffs, and hands-on experimental validation, including the measurement and verification of key fibre properties. The successful candidate will work with internal teams with diverse technical expertise, and external partners, to translate performance requirements into practical technical direction for advanced fibre technologies. We welcome candidates from both advanced industrial photonics environments and leading research groups who combine strong physical intuition with practical experimental and engineering judgement. Responsibilities: • Use simulation and analytical tools to evaluate the behaviour and performance of advanced fibre designs and fibre-based optical systems. • Assess modal properties, loss mechanisms, dispersion, coupling, and other key fibre characteristics relevant to demanding optical applications. • Design and execute experiments to measure, verify, and interpret fibre properties and subsystem performance. • Correlate simulation and experimental results to build understanding, validate assumptions, and guide development deci
