Physical Design Engineer, Sonoma

Job Description
We are seeking expert Physical Design Engineers to lead top-level signoff activities for complex SoCs on advanced nodes (5nm / 3nm / 2nm).
The ideal candidate will have multiple full-cycle tapeouts and the technical depth to independently drive signoff-to-tapeout closure.
This role requires close collaboration with RTL, Timing, Power Integrity, and Foundry teams to ensure structural integrity, timing convergence, and power reliability for high-performance silicon.
Core Responsibilities
Drive top-level signoff for high-performance SoC designs.
Collaborate with RTL, Physical Design, STA, and cross-functional teams.
Execute, analyze, and debug complex full-chip design challenges.
Develop and optimize signoff methodologies to improve TAT (Turn-Around Time) and PPA (Power, Performance, Area).
Identify and mitigate timing, power, reliability, and clocking risks at full-chip level.
Deliver signoff closure and tapeout readiness independently.
Specialized Tracks (Expertise in at least one area)
Track 1: Top-Level EMIR (Power Integrity)
Perform Static & Dynamic IR Drop analysis.
Execute Electromigration (EM) verification.
Optimize PDN for reliability and noise margins.
Tools: Ansys RedHawk-SC, Cadence Voltus.
Track 2: Top-Level Timing & STA
Own full-chip STA across all PVT corners and modes.
Manage MMMC timing closure and ECOs.
Tools: Synopsys PrimeTime, Cadence Tempus.
Track 3: Top-Level Clock Distribution
Design and analyze clock architectures (H-Tree, Mesh, Hybrid).
Drive CTS for ultra-low skew and balanced latency.
Tools: Cadence Innovus, Synopsys Fusion, SPICE simulation.
Required Qualifications
BS/MS in Electrical/Computer Engineering or related field.
8+ years of experience in Physical Design/Signoff.
Proven track record with 2–3 successful tapeouts on advanced nodes (5nm, 3nm, 2nm).
Deep knowledge of OCV, AOCV/POCV, statistical timing methodologies.
Strong scripting skills (Tcl, Python, Perl).
Excellent debugging, analytical, and communication skills.
Preferred Skills
Experience with 2.5D/3D IC packaging signoff.
Familiarity with foundry signoff methodologies (TSMC, Samsung, Intel).
Background in HPC, AI accelerators, or large-scale SoC designs.
