About the role

Physical Design Engineer role focused on transforming high-performance architectural concepts into production-ready silicon, owning the physical implementation flow from synthesis to tape-out, and collaborating with RTL design to meet timing, electrical, and physical verification targets for a custom AI accelerator.

Responsibilities

  • Drive Synthesis and Place-and-Route: Own the physical implementation flow from RTL synthesis through placement, clock tree synthesis (CTS), and routing for high-performance blocks.
  • Maximize PPA: Optimize layout topologies to maximize cell density and utilization, architect robust PDN to minimize IR drop and meet aggressive frequency targets on advanced foundry nodes.
  • Close Timing & Electricals: Conduct static timing analysis (STA), fix setup/hold violations across complex clock domains, and resolve signal integrity (SI), electromigration (EM) and IR-drop constraints.
  • Execute Physical Verification: Run and debug sign-off physical verification, including DRC, LVS, and Antenna rule compliance.
  • Co-Design with RTL: Partner with RTL team to provide early physical feedback on logic structures, pipeline depth, and routing congestion to streamline implementation closure.
  • Advance Flow Automation: Integrate and develop AI-driven EDA tools and workflows to accelerate physical implementation and design closure.

Qualifications

  • Bachelor’s degree in Electrical Engineering or Computer Engineering
  • 5+ years practical industry experience with advanced process nodes (7nm or below)
  • Deep hands-on proficiency with industry-standard physical design, timing, and sign-off tools (e.g., Innovus, Fusion Compiler, PrimeTime, RedHawk)
  • Proven track record running logic synthesis, integrating compiled memory macros, and managing multi-voltage design techniques using UPF/CPF
  • Exceptional debugging skills with first-principles approach to congestion, timing slack, and power density in highly utilized designs
  • Collaborative mindset and bias for action to co-design effectively with RTL and architecture teams
