• Perform floor planning, power planning, placement, clock tree synthesis (CTS), routing, and physical verification.
• Optimize designs for Power, Performance, and Area (PPA) targets.
• Achieve timing closure across multiple corners and modes.
• Analyze and resolve setup, hold, transition, capacitance, and noise violations.
• Develop and maintain timing constraints (SDC) and STA signoff methodologies.
• Perform EMIR (Electromigration & IR Drop) analysis and closure.
• Collaborate with RTL, DFT, STA, and Signoff teams to ensure successful tapeout.
• Debug physical design issues and drive design convergence within project schedules.

• Strong experience in Physical Design and PnR flow.
  • Placement & Optimization
  • Clock Tree Synthesis (CTS)
  • Routing
  • Timing Closure
  • Static Timing Analysis (STA)
  • Timing Constraints (SDC)
  • EMIR Analysis
  • PPA Optimization
• Experience with industry-standard EDA tools such as:
  • Cadence Innovus (optional)
  • Red Hawk / Voltus (EMIR)
• Good understanding of low-power design techniques and signoff methodologies.

• Bachelor's or Master's degree in Electrical/Electronics Engineering.
• Experience in advanced nodes (7nm/5nm/3nm preferred).
• Strong debugging and problem-solving skills.
• Experience working with cross-functional silicon teams.
