Physical Design Engineer

7Rays Semiconductors, San Jose, CA, United States


We are seeking a Physical Design contractor with strong synthesis and implementation expertise to support large, timing-critical designs at advanced technology nodes.

Key Responsibilities:

  • Perform synthesis using Cadence Genus for large, timing-challenged designs
  • Drive PPA (power, performance, area) optimization through synthesis and early implementation stages
  • Develop and refine floorplans using Cadence Innovus
  • Collaborate closely with RTL teams to provide timely feedback on design quality, constraints, and architectural tradeoffs
  • Partner with external P&R teams to iterate toward timing closure and PPA optimization
  • Identify and address timing bottlenecks early in the flow to improve convergence

Preferred Qualifications:

  • Proven experience with large-scale SoC or AI-class designs
  • At least 5 years of PD experience
  • Hands-on experience at advanced / cutting-edge technology nodes (e.g., N5, N3 or below)
  • Strong understanding of timing closure and correlation between synthesis and implementation
  • Hands-on experience with Cadence Genus and Innovus
  • Ability to work cross-functionally with RTL, architecture, PD, and external implementation teams
