Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems. \nQuantum 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. \nOur 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. \nIn 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. \nPsiQuantum 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. \nQuantum 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. \nCome join us. \nJob Summary:\nThe OS Core Team at PsiQuantum works closely alongside engineers and scientists in the electronics, system architecture, and validation teams and is responsible for building the scalable, distributed, fault-tolerant control plane and operating system for utility scale photonic quantum computers. Our team is responsible for orchestration, scheduling, kernel architecture, co-design, calibration, validation, providing abstractions, systems, and operating software for the immense heterogenous fabric of co-processors, networks, and photonics that are critical to the success of our company’s goal of building the world’s first useful quantum computer. As a Senior Software Engineer, Calibration & Control you will design and implement algorithms, controls, and software that keep our quantum processors in spec 24×7x365. \nResponsibilities:\nThe core of our system revolves around a high performance, scalable graph database which contains critical information to control and manage PsiQuantum computing systems. Your role is to scale and extend the current core database systems to support the massive increase in size complexity of our systems. \nDaily functions: \nData systems design and implementation. \nParticipate in design and code reviews. \nCollaborate across software, hardware, and research teams at PsiQuantum. \nTesting and maintenance of database software. \nChampion and serve as an exemplar of good software development practices at PsiQuantum. \nExperience/Qualifications:\n15+ years experience with Python or C++ in a system software context. \nDesign and implementation of large scale distributed storage systems, emphasis on graph databases. \nProven track record of developing and shipping reliable, performant software in a high scale or mission critical context. \nBachelors degree in a technical discipline preferred, or equivalent experience. \nWays to stand out: \nExperience in graph database systems such as Nebula, neo4j, Gravlax. \nExperience in high performance computing and data design. \nExperience in computer architecture. \nExperience in high performance networking. \nExperience with highly scalable distributed systems in a reliability and up-time critical environment. \nPhD in a related technical discipline is a plus but not required. \n[We are open to adjusting the compensation to experience level]\nNote: PsiQuantum will only reach out to you using an official PsiQuantum email address and will never ask you for bank account information as part of the interview process.
