On-siteEngineering$160k–$190k/yrFull-time

Responsibilities

  • Design, analyze, and simulate Photonic Integrated Circuit (PIC) building blocks (e.g., Mach–Zehnder modulators, photodiodes, DWDM filters, waveguides, couplers/splitters, tapers, and switches) on silicon photonics and InGaAs/InP platforms
  • Define requirements and specifications for PICs and their optical/electrical interfaces
  • Design and model package-level optical interfaces, including edge and grating couplers
  • Work with DSP, electro-optics, ASIC, and other engineering teams to define system functions across hardware and software
  • Perform PIC routing and layout
  • Measure and characterize PIC optical and electrical building blocks
  • Develop and automate test solutions for lab validation, quality screening, and manufacturing metrology
  • Partner with manufacturing and test teams on production test development and qualification of PICs
  • Use simulation tools (e.g., Lumerical, Klayout, COMSOL, HFSS) to support design and verification
  • Contribute to RF, analog, and mixed-signal design efforts as needed
  • Interface with suppliers to provide technical feedback and test requirements to develop reliable processes

Qualifications

  • Master’s degree in electrical engineering, computer engineering, optical engineering, or applied physics
  • 2+ years of experience in photonics or electro-optical IC design
  • Hands-on familiarity with optical/RF test equipment (e.g., spectrum analyzers, VNAs, VSGs, high-speed oscilloscopes, BERTs)
  • Willingness to work extended hours and weekends as needed

PREFERRED EXPERIENCE

  • PhD in electrical engineering, computer engineering (electro-optics emphasis), optical engineering, or applied physics
  • Experience with electrical simulation tools (e.g., SPICE)
  • Familiarity with DSP concepts (e.g., FFE, DFE, CTLE) and optical communications metrics (e.g., OSNR, receiver sensitivity, OMA, optical filtering)
  • Strong circuit design and analysis skills across linear and non-linear blocks (e.g., modulator drivers, TIAs, CTLEs, filters, LNAs/PAs)
  • Experience designing wideband circuits for >100 Gb/s SerDes links with bandwidths in the tens of GHz
  • Familiarity with high-speed modulation formats and link protocols (e.g., NRZ, PAM4)
  • Experience designing RF/DC probe-card PCBs
  • Experience characterizing PIC/EIC performance for high-speed optical SerDes systems
