Senior Photonic Layout Design Engineer

NVIDIA NVIDIA · Semiconductors · Santa Clara, CA

NVIDIA is seeking a Senior Photonic Layout Design Engineer to handle high-speed mixed-signal & Silicon Photonic Designs. The role involves physical design and verification of photonic integrated circuits (PICs), from concept to manufacturing. Responsibilities include layout execution, tape-out ownership, verification, and developing AI-assisted design methods and automation scripts.

What you'd actually do

  1. Lead complex, full-loop manual and automated layout designs for waveguides, modulators, photodetectors, and mixed-signal functions (high-speed/general I/Os, ESD structures). Drive the full tape-out process, including floor planning, waveguide routing, and mask data preparation.
  2. Execute rigorous post-layout verification (DRC, LVS, fill, density) across multiple stepping versions. Trace defect sources, mitigate layout-dependent issues, and ensure DRC/LVS cleanliness prior to tape-out.
  3. Own the layout of complex test structures, active/passive full loops, and certification vehicles with large Design of Experiments (DOEs) to optimize for process windows.
  4. Develop and implement AI-assisted design methods, layout automation scripts, and custom Pcells to improve productivity, reduce development cycle times, and customize DRC/LVS checking flows.

Skills

Required

  • BS, MS, or Ph.D. in Electrical Engineering, Physics, or a closely related field (or equivalent experience).
  • At least 6+ years of hands-on, full-chip layout design experience in semiconductor, analog, or silicon photonics industries.
  • Deep understanding of analog circuit layout, Silicon Photonic constraints, and device physics within advanced sub-micron CMOS and SiPh technologies.
  • Proven expertise with Cadence Virtuoso (Custom Layout, SDL) and industry-standard verification suites (Calibre, Hercules, ICV, Dracula, or Primeyield).
  • Strong proficiency in programming and scripting languages (Python, SKILL, Perl, TCL, or C++) for layout automation, file I/O, data processing, and tape-out flows.

Nice to have

  • sophisticated automation capabilities
  • proven track record of first-time success on high-density chip designs
  • Ability to optimize workflows using best-known methods (BKMs)
  • proactively collaborate with integration, and design rule teams
