Principal Engineer - Analog and Mixed-Signal Physical Design

Microsoft Silicon, Cloud Hardware, and Infrastructure Engineering (SCHIE) is the team behind Microsoft’s expanding Cloud Infrastructure and is responsible for powering Microsoft’s Intelligent Cloud mission. SCHIE delivers the core infrastructure and foundational technologies for Microsoft’s online businesses, including Azure, Microsoft 365, Teams, OneDrive, Xbox, and other global services.

As Microsoft’s cloud and silicon investments continue to grow, the ability to deliver advanced analog and mixed-signal silicon IP on schedule, at high quality, and with strong execution discipline is critical. We are looking for a Principal Engineer – Analog and Mixed-Signal Physical Design to serve as a hands-on technical contributor who can drive physical implementation, timing closure, physical design verification, and custom IP integration for analog and mixed-signal designs.

This is a hands-on Principal role, not a planning-only or coordination-only position. The ideal candidate brings deep Fusion Compiler-based physical implementation expertise, strong timing closure and physical verification experience, and sufficient custom layout understanding to partner effectively with analog design and layout teams while directly executing critical implementation and debug work.

#SCHIE

• Drive hands-on physical design implementation for analog and mixed-signal IP blocks, including floorplanning, placement, routing, optimization, ECO implementation, and closure debug.
• Execute and guide Fusion Compiler-based APR flows, with direct ownership of implementation quality, timing convergence, physical design verification readiness, and signoff closure.
• Serve as the technical bridge between analog design, custom layout, physical design, timing, physical verification, CAD/methodology, and silicon integration teams.
• Perform timing analysis and closure activities across analog and mixed-signal-adjacent IP, including constraint review, timing debug, implementation tradeoffs, and signoff readiness.
• Partner with custom layout engineers to ensure layout feasibility, integration quality, physical verification closure, and timing/implementation convergence without positioning this role as a pure custom layout owner.
• Lead internal and external/V-team execution through hands-on technical direction, deliverable review, quality expectations, and schedule alignment.
• Debug and resolve complex implementation issues related to physical design, timing closure, extraction, physical verification, layout integration, reliability, and release readiness.
• Coordinate implementation activities across architecture, circuit design, layout, CAD/methodology, verification, product engineering, and silicon integration stakeholders.
• Contribute to design reviews, implementation quality improvements, signoff planning, and broader execution strategy for analog, mixed-signal, and custom IP physical design deliverables.
• Mentor engineers and provide Principal-level technical leadership while remaining directly engaged as a doer in critical implementation and closure work 

Required Qualifications

• Doctorate in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 3+ years technical engineering experience OR Master's Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 6+ years technical engineering experience OR Bachelor's Degree in Electrical Engineering, Computer Engineering, Computer Science, or related field AND 8+ years technical engineering experience OR equivalent experience.

Ability to meet Microsoft, customer, and/or government security screening requirements are required for this role. These requirements include but are not limited to the following specialized security screenings: Microsoft Cloud Background Check.
