TL;DR · Optical Design Engineer

The Optical Design Engineer joins the Silicon Photonics product team to develop hardware platforms for switching, routing, and wireless products. This role involves full-lifecycle responsibility for Photonic Integrated Circuit (PIC) product designs, spanning from initial simulation and layout to final GDS tapeout and post-fabrication validation. The engineer will co-design optimized opto-electronic chipsets to meet system-level specifications and manage multiple parallel designs through the design-tapeout-Fab-validation cycle. Key responsibilities include designing passive and active photonic device layouts and owning small test-chips for next-generation products. Required technical skills include experience with Cadence Virtuoso, silicon photonics circuit modeling, and fabrication processes. Candidates should also possess proficiency in lab measurements and data analysis using Matlab, Labview, and Python, alongside knowledge of OE/RF simulation tools like HFSS.

What you'll do

  • Own the PIC product design cycle from initial simulation and layout to final GDS tapeout.
  • Perform post-Fab validation on silicon photonics products.
  • Co-design optimized opto-electronic chipsets with the EIC and module teams to meet system specifications.
  • Manage multiple parallel PIC designs through the design-tapeout-Fab-validation cycle simultaneously.
  • Design and own small test-chips to facilitate the development of next-generation products.
  • Conduct lab measurements and data analysis using tools like Matlab, Labview, and Python.
  • Generate GDS layouts for both passive and active photonic devices using Cadence Virtuoso.

What we're looking for

  • Must have a Bachelor's plus 5 years of related experience, a Master's plus 3 years, or a PhD.
  • Must have prior experience in silicon photonics circuit modeling, layouts, tapeouts, and fabrication processes.
  • Must have experience with photonic device layouts for passive and active components using EDA tools like Cadence Virtuoso.
  • Must have experience with lab measurements, data analysis, and automation using Matlab, Labview, or Python.
  • Preferred experience working with cross-functional engineering teams.
  • Preferred experience with OE/RF simulation, including S-parameters and co-simulation with electronic drivers or TIAs.
  • Preferred experience working with silicon photonics foundries.
  • Preferred experience using AI tools for data analysis, testing, and validation.
