Key Responsibilities

• Execute the complete Physical Design flow from Netlist to GDSII.
• Perform Floorplanning, Power Planning, Placement, CTS, Routing, and Physical Verification.
• Drive timing closure while meeting PPA (Performance, Power, and Area) targets.
• Perform congestion analysis and optimize placement and routing.
• Analyze and fix setup/hold timing violations across all design corners and modes.
• Perform physical signoff including DRC, LVS, IR Drop, EM, and antenna checks.
• Collaborate with RTL, DFT, STA, and Packaging teams to achieve successful tape-out.
• Debug and resolve implementation issues while ensuring design quality.
• Support ECO implementation and timing closure activities.
• Ensure successful tape-out on advanced technology nodes.
