Physical Design Engineer

The role

You will take designs from netlist to GDSII. You will own floorplanning through closure on real silicon programs and help Voltai's AI learn how expert physical designers make decisions.

What you will do

• Own block-level and full-chip physical implementation including floorplanning, placement, clock tree synthesis, and routing.
• Drive timing, power, and congestion closure with synthesis and STA teams.
• Close physical verification (DRC/LVS) and power integrity (IR drop, EM) for signoff.
• Build and improve place-and-route flows and automation.
• Evaluate AI-generated floorplans and implementation decisions.
• Work directly with customer teams on implementation challenges.

Required qualifications

• 5+ years of physical design experience with multiple production tapeouts.
• Deep experience with Innovus or Fusion Compiler/ICC2.
• Strong understanding of timing closure, clock tree synthesis, and power distribution networks.
• Experience at advanced nodes (7nm and below).
• Strong Tcl and Python scripting.

Nice to have

• Full-chip integration or hierarchical design experience.
• Experience with high-speed or low-power designs.
• Interest in AI or machine learning applied to physical design.
