About

We are seeking a Senior/Staff Physical Design Engineer with deep expertise in top-level clock architecture and CTS implementation for advanced-node SoCs (5nm / 3nm / 2nm). The ideal candidate will have strong experience designing large-scale clock distribution networks including H-Tree, Mesh, and Hybrid architectures while driving ultra-low skew clock signoff. You will collaborate with Physical Design, STA, RTL, and Power teams to ensure robust clock quality and tapeout readiness. Key Responsibilities Design and optimize top-level clock distribution architectures. Implement and analyze: H-Tree Clock Mesh Hybrid Clock Structures Drive CTS for low skew and balanced latency. Optimize clock power using advanced gating techniques. Validate clock signal integrity and duty cycle distortion (DCD). Debug large-scale clocking issues across full-chip integration. Collaborate with STA and PD teams for clock-timing convergence. Develop scalable methodologies for clock signoff closure. Ensure robust clock quality at advanced nodes and large die scale.
