We are seeking a Senior/Principal Power Signal Integrity Engineer to help define the electrical architecture of next-generation Cryo-CMOS quantum control systems. You will design and analyze power delivery signal integrity and electrical isolation strategies across silicon package and board-level this role youll help solve one of the industrys hardest mixed-signal problems: getting large-scale digital control systems to work alongside extremely sensitive qubit control and measurement circuitry. This work draws on expertise in power delivery networks mixed-signal integration electromagnetic coupling and silicon-package-board co-design.

Microsofts mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset innovate to empower others and collaborate to realize our shared goals. Each day we build on our values of respect integrity and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

• 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.
