At Microsoft Quantum, we aim to empower science and scientists to solve the world's biggest problems by realizing advanced computing platforms at the intersection of high-performance computing, artificial intelligence (AI), and quantum information technology. For more information about our team, visit https://www.microsoft.com/en-us/quantum. We are seeking a Senior Quantum Engineer – Digital Control Systems to design and implement digital control infrastructure for cryogenic quantum control systems. This role sits within the quantum control team, which develops integrated control electronics that interface directly with quantum devices and enable scalable quantum systems. You will contribute to the design, implementation, and validation of high-performance digital control systems operating across room-temperature and cryogenic environments. This is a hands-on, multidisciplinary role at the intersection of digital design, system architecture, and experimental validation. You will work closely with system architects, analog designers, and experimental physicists to translate system-level requirements into robust, timing-critical digital implementations and drive performance across the control stack. This role involves deep, technical work in a small, collaborative environment. We are looking for someone who is as passionate about their own contribution as they are to empowering and inspiring others. The candidate will be responsible for contributing to the technical direction of system development based on system requirements, hardware constraints, experimental results, and input from cross-functional colleagues.
