About the Role

You will implement physical-design blocks from floorplanning through tapeout. You will run implementation and signoff flows, pursue timing closure, analyze power and physical-verification issues, automate work with scripts, and collaborate with RTL, synthesis, DFT, packaging, and backend partners.

Requirements

  • BS/MS in EE/CE or a related field
  • 0–3 years of physical design experience
  • Physical design
  • Floorplanning
  • Placement
  • Clock tree synthesis
  • Routing
  • Timing closure
  • Static timing analysis
  • Innovus or ICC2
  • DRC
  • LVS
  • Tcl or Python
  • Tapeout
  • IR drop
  • Electromigration
  • Signal integrity
  • VLSI design
  • Computer architecture
  • AI accelerator
  • SRAM
  • SerDes
  • LPDDR
  • Chiplet
  • Advanced packaging

Responsibilities

  • Implement blocks through floorplanning, macro placement, and power planning.
  • Run clock tree synthesis, place and route, routing optimization, and timing closure.
  • Support signal-integrity, IR/EM, ECO, metal-fill, and tapeout signoff activities.
  • Maintain and improve power-grid, power/ground-tile, and bump-planning flows.
  • Run congestion analysis and wire estimation.
  • Apply hierarchical implementation and partitioning strategies.
  • Run and debug Innovus-based implementation flows.
  • Write Tcl and Python scripts to automate tasks and parse reports.
  • Analyze and fix timing, power, area, congestion, DRC, LVS, EM, and IR issues.
  • Work with backend design-services partners and participate in implementation reviews.
  • Use AI-enabled tools for QoR, congestion, routing, and floorplan analysis.

Benefits

  • Company-paid medical, dental, and vision insurance for employees and dependents
  • Company-paid life and disability coverage
  • Supplemental hospital, critical illness, and accident coverage
  • Unlimited paid time off
  • 13 paid company holidays
  • Remote-first work
  • Company-provided computer and home office setup
  • Equity
  • 401(k) matching from day one
  • H-1B visa transfer support for eligible candidates
