Senior Digital Designer (Front-End & Back-End)

Quantum Motion is seeking a Senior Digital Designer to lead the full lifecycle of ultra-low-power, high-density cryogenic control ICs for scalable quantum computing systems. This senior role operates at the intersection of sub-Kelvin sub-system electronics and quantum processor architectures, addressing the critical interconnect bottleneck. The position involves designing digital logic blocks for cryogenic environments, spanning from microarchitecture specification to tape-out signoff. The ideal candidate will drive the development of fault-tolerant quantum computing scale-out solutions.
