TL;DR · Senior Silicon Photonics Design Engineer, RFIC Engineering

Sr. Silicon Photonics Design Engineer (RFIC Engineering) joins a cross-disciplinary team to develop next-generation photonic integrated circuits for space and ground infrastructure. The role involves designing, analyzing, and simulating optical building blocks like MZM, Microring modulators, Ge photodiodes, and waveguides across silicon photonics and InGaAs/InP platforms. Responsibilities include deriving specifications for PIC systems, modeling package optical interfaces, performing IC floor planning, and characterizing high-speed optical link components. The engineer will collaborate with system architects and ASIC engineers to partition hardware and software functions while assisting in automated test equipment development. Required expertise includes experience with Lumerical, COMSOL, and HFSS simulation tools. Preferred skills include proficiency in Spectre or ADS, knowledge of co-package optics, and experience with high-speed SerDes links exceeding 100Gbps data rates using NRZ/PAM4 modulation schemes for advanced networking connectivity.

What you'll do

  • Design, analyze, and simulate optical building blocks like modulators, photodiodes, and waveguides in silicon photonics and InGaAs platforms.
  • Derive technical specifications for Photonics IC systems and integrated circuits.
  • Design and model package optical interfaces including edge couplers and grating couplers.
  • Perform IC floor planning and layout for photonic integrated circuits.
  • Evaluate, characterize, and measure electrical and optical building blocks of high-speed optical link solutions.
  • Develop automated test lab equipment to support measurements and testing.
  • Collaborate with manufacturing engineers on the production testing and qualification of PIC circuits.

What we're looking for

  • Bachelor's degree in electrical engineering, computer engineering, or computer science.
  • Master's degree or PhD in electrical engineering, computer engineering, or applied physics.
  • 5+ years of experience in photonics or electro-optical integrated circuit design.
  • Proficiency with simulation tools such as Lumerical, COMSOL, and HFSS.
  • Experience using electrical simulation tools like Spectre or ADS.
  • Knowledge of advanced packaging for co-package optics (CPO) solutions.
  • Expertise in high-speed SerDes architecture, modulation schemes, and wideband circuit designs exceeding 100Gbps.
  • Must be a U.S. citizen, permanent resident, or eligible for required export control authorizations.
