Physical Design Engineer

OpenAI OpenAI · AI Frontier · San Francisco, CA · Scaling

OpenAI is seeking a Physical Design Engineer to design custom silicon for AI accelerators. This role involves developing tools, flows, and methodologies for physical implementation, owning physical implementation of blocks, and collaborating with RTL designers to optimize for performance, power, and area. The role requires expertise in physical design, methodology development, and hands-on experience with complex silicon designs.

What you'd actually do

  1. Develop, build and own tools, flows and methodologies for physical implementation
  2. Own physical implementation of floorplan blocks from floorplanning to final signoff
  3. Collaborate with RTL designers to drive optimal block implementation solutions
  4. Analyze and optimize design for timing, power, and area trade-offs, working in collaboration with EDA vendors and ASIC partners
