• Role Overview  
• Astera Labs is scaling the connectivity fabric behind the world's largest AI clusters, and reliable power delivery is non-negotiable in the SoCs we ship. As a Technical Lead Physical Design Engineer- Power Integrity , you will own IR drop and electromigration (IR/EMIR) analysis and closure across Astera Labs' connectivity ASIC portfolio, driving power integrity from early floorplan through tapeout.  
• You will partner closely with power grid, floorplan, package, and implementation teams to ensure stable power delivery, meet foundry sign-off criteria, and prevent long-term reliability issues in production silicon. This role is fully on-site at our San Jose, CA location.  
• Key Responsibilities  
• Power Integrity Analysis & Sign-off   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  
• Design Convergence & Cross-Functional Partnership   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  
• Methodology & Automation   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  
• Basic Qualifications:  
• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field  
• 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  
• Preferred Qualifications:  
• 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  
• Salary range is $160,000 to $200,000 depending on experience, level, and business need. This role may be eligible for discretionary bonus, incentives and benefits.
