5+ years of experience in IR drop, electromigration analysis, and power integrity sign-off for complex SoCs at advanced nodes (7nm and below)
Deep expertise in power grid design, PDN analysis, and EM reliability mitigation, including static and dynamic IR methodologies and foundry sign-off criteria
Proficiency with Cadence Voltus and/or Synopsys RedHawk-SC / PrimeTime PX
Strong scripting ability in Tcl, Python, and/or Perl for flow automation and data analysis

Nice To Haves

Master's degree in Electrical Engineering or a related field
Power integrity experience on high-speed SerDes, Ethernet PHY, or PCIe designs
Package-level power delivery analysis / co-simulation, including advanced packaging or multi-die integration exposure
Experience building EMIR methodology infrastructure that scales across multiple concurrent tapeout programs

Responsibilities

Own static and dynamic IR drop and electromigration analysis at block and full-chip levels, driving closure to foundry sign-off criteria
Drive UPF-based power domain planning and power-aware sign-off across multi-voltage designs
Analyze thermal and current density issues and recommend design modifications to ensure long-term reliability
Collaborate with package, power grid, and floorplan teams to identify and resolve voltage drop hotspots and EM violations early in the design cycle
Provide actionable feedback to implementation teams on power grid reinforcement, decap strategy, and hard-macro / SerDes integration
Partner with RTL, STA, verification, IP vendors, and foundry to drive power integrity convergence through tapeout
Develop and refine EMIR runsets, stimulus methodologies, and reporting dashboards to improve predictability and reduce iterations
Build and maintain EMIR analysis flows and automation infrastructure for efficient multi-corner analysis
Deliver clear, actionable root-cause analysis and mitigation guidance at both block and full-chip levels
