Senior Principal Power and Signal Integrity Engineer

What you'll do

• Define power integrity and signal integrity strategies for next-generation Cryo-CMOS quantum control systems.
• Manage electrical integrity across silicon, package, PCB, and system-level implementations.
• Architect and optimize power delivery networks from on-chip grids to board-level distribution.
• Develop isolation strategies to separate digital switching noise from sensitive analog and RF signals.
• Analyze and mitigate electromagnetic coupling, crosstalk, and mixed-signal interference mechanisms.
• Lead silicon-package-board co-design activities with ASIC, package, and quantum hardware teams.
• Establish design methodologies, validation plans, and signoff criteria for power and signal integrity.
• Correlate simulation results with laboratory measurements to guide critical architecture decisions.

What we're looking for

• A Doctorate in Physics or Engineering with 1+ years of experience, a Master's with 4+ years, or a Bachelor's with 6+ years is required.
• Candidates must be able to pass Microsoft Cloud Background Checks and meet export control requirements (ITAR/EAR).
• Ability to provide proof of citizenship or U.S. permanent residency for access to export-controlled information.
• Ability to leverage AI tools for performance modeling, research gathering, and task automation in an AI-first environment.
• Experience with power integrity and signal integrity for complex mixed-signal systems (preferred).
• Experience designing power delivery networks across ASICs, semiconductor packages, and PCBs (preferred).
• Experience using industry-standard simulation tools like Synopsys RaptorX, Ansys HFSS, or Cadence Clarity (preferred).
• Master's Degree in Physics, Engineering, or related field AND 4+ years.
