Senior/Principal Power and Signal Integrity Engineer

Full Job Description

Define and drive power integrity and signal integrity strategy for next-generation Cryo-CMOS quantum control systems. Own electrical integrity across silicon, package, PCB, interconnect, and system-level implementations. Architect and optimize power delivery networks spanning on-chip power grids, advanced packages, and board-level power distribution. Develop isolation strategies that enable large-scale digital switching circuitry to coexist with highly sensitive analog, RF, and qubit-control signals. Lead analysis and mitigation of power delivery, switching noise, electromagnetic coupling, crosstalk, and mixed-signal interference mechanisms. Drive silicon-package-board co-design activities in partnership with ASIC, package, board, system, and quantum hardware teams. Establish design methodologies, validation plans, and signoff criteria for power integrity and signal integrity closure. Correlate simulation results with laboratory measurements and provide technical leadership for critical architecture decisions across the organization. Other: Embody our culture and values.
