TL;DR · Principal Optical Engineer

The Principal Optical Engineer joins the Cloud Hardware Systems Engineering team to drive architectural design and production roadmaps for next-generation optical interconnects in hyperscale AI infrastructure. This role serves as a technical leader for near-package optics, co-packaged optics, silicon photonics, and advanced packaging. You will translate system requirements into specifications for bandwidth density, latency, and signal integrity while building system models for photonic-device performance and thermal behavior. Key responsibilities include guiding proof-of-concept designs through manufacturing ramp, performing laboratory characterization, and defining verification strategies at the wafer, die, and rack levels. You will utilize expertise in VCSELs, modulators, photodetectors, and heterogeneous integration technologies like chiplets and hybrid bonding to solve complex interconnect challenges within AI scale-up networks and high-bandwidth fabrics.

What you'll do

  • Own the end-to-end architecture and multi-generation roadmap for NPO and CPO optical interconnects in AI scale-up networks.
  • Translate system and network requirements into technical specifications for bandwidth, latency, energy, and signal integrity.
  • Define silicon-photonic subsystem architectures including optical engines, modulators, photodetectors, and laser-source strategies.
  • Build system models connecting photonic-device performance with SerDes channels, package parasitics, and thermal behavior.
  • Provide technical leadership in laboratory characterization, link bring-up, failure analysis, and simulation correlation.
  • Define verification, qualification, reliability, and manufacturing-test strategies across wafer, die, package, and system levels.
  • Guide proof-of-concept designs through product definition, manufacturing readiness, and large-scale fleet deployment.
  • Set technical direction with foundries, OSATs, and component suppliers to ensure roadmap alignment and supply continuity.

What we're looking for

  • Master's degree in a relevant engineering field and 7+ years of experience, or a Bachelor's degree and 8+ years of experience.
  • Ability to pass a Microsoft Cloud Background Check.
  • Must provide proof of U.S. citizenship, permanent residency, or other protected status for export-controlled information access.
  • Technical experience architecting or developing silicon photonics, VCSELs, optical engines, NPO, CPO, or related optical interconnects (preferred).
  • Hands-on laboratory experience characterizing and debugging photonic devices or optical links using high-speed electrical test equipment (preferred).
  • Experience leading architecture or product development across multiple disciplines and phases of the lifecycle (preferred).
  • Doctorate degree in a relevant field and 8+ years of experience, or Master's and 10+ years, or Bachelor's and 14+ years (preferred).
  • Experience with advanced photonic or semiconductor packaging, including optical coupling, fiber attach, and thermal design (preferred).
