Senior Implementation Methodology Engineer

Own and continuously improve the end-to-end RTL2GDS implementation methodology — covering synthesis, place & route, CTS, and equivalence checking — for advanced-node CPU builds. Evaluate new EDA tools and process node capabilities. Deliver clear adoption recommendations. Serve as the technical liaison between internal teams and EDA vendors (Synopsys, Cadence) to resolve tool issues and influence vendor roadmaps. Define and enforce implementation methodology BKMs and flow standards across development teams; maintain user documentation and lead training on tools and flows. Build and complete rigorous A/B and multi-variant experiments to quantitatively compare flows, engine settings, and optimization strategies for QoR impact. Drive aggressive PPA targets throughout the full implementation cycle. Conduct deep root-cause analysis on timing closure bottlenecks, power limiters, and long-tail QoR issues. Develop methodologies to resolve these problems at scale. Architect and build Python/TCL/Perl automation frameworks that reduce manual engineering effort and improve design turnaround time across implementation teams. Identify systemic efficiency bottlenecks across the implementation flow and eliminate them through targeted automation, data-driven regression infrastructure, and AI/ML-assisted flow optimization. Partner with architecture, RTL, DFT, physical build, and sign-off teams to surface PPA opportunities early and translate methodology improvements into measurable silicon impact.
