Responsibilities

BS/MS/PhD in EE/CE or equivalent practical tapeout experience
8–12+ years (typical Principal level) in physical verification (PV) signoff for digital SoCs/ASICs with multiple successful tapeouts
Strong hands-on expertise in DRC/LVS/DFM closure, including hierarchical LVS debugging, connectivity issues (opens/shorts), and waiver governance
Proven ability to drive signoff end-to-end: methodology definition, closure execution, and tapeout release gating/documentation
Proficiency with major PV tool stacks (e.g., Calibre-class flows) and strong understanding of PDK/rule deck intent and rule-debug workflow
Solid understanding of how physical implementation choices (P&R/CTS/routing/ECOs) impact PV outcomes, schedule risk, and manufacturability
Strong scripting/automation skills (Python/Tcl/shell) for reproducible flows, regression scaling, and metrics/dashboards
Demonstrated cross-functional execution with PD/STA/power/IP owners to drive closure and make pragmatic signoff tradeoffs
Experience supporting block-to-top signoff integration and ensuring third-party IP meets tapeout-quality acceptance criteria
Advanced node experience (28nm or smaller) and associated DFM complexity
Experience in regulated / high-reliability products where traceability and signoff rigor are critical
Familiarity with reliability/power integrity signoff concepts (EM/IR fundamentals) and coordination across signoff streams
Experience interfacing with foundry/PDK vendors on rule updates, interpretations, and signoff collateral alignment
