Sr. Silicon Photonics Design Engineer (RFIC Engineering)
On-siteRedmond, Washington, United States
Job Summary
Design, analyze, and simulate optical building blocks such as MZM, Microring modulators, Ge Photo diodes, and waveguides across silicon photonics and InGaAs/InP platforms. Derive specifications for Photonics IC systems, model package optical interfaces, and perform IC floor planning and layout. Collaborate with system architects, DSP, and ASIC engineers to partition functions between hardware and software domains while evaluating and characterizing high-speed optical link solutions. Assist in developing automated test lab equipment and work with manufacturing engineers on production testing and qualification of PIC circuits. Requires 5+ years of photonics IC design experience, proficiency in Lumerical, COMSOL, and HFSS, and familiarity with RF, analog, and mixed-signal circuits. Ability to work long hours and weekends as necessary to support critical milestones.
Required Qualifications
- Bachelor's degree in electrical engineering, computer engineering, or computer science
- 5+ years of photonics or electro-optical integrated circuit design
- Ability to work long hours and weekends as necessary to support critical milestones
- U.S. citizen or national, U.S. lawful permanent resident, Refugee under 8 U.S.C. § 1157, or Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State
Desired Qualifications
- Master's degree or PhD in electrical engineering, computer engineering (with emphasis on electro-optics IC design), or applied physics
- Experience using electrical simulation tools such as Spectre, ADS
- Knowledge of advanced packaging for a co-package optics (CPO) solution
- Electrical circuit design skills, and experience performing analysis and simulation linear/non-linear circuits such as high bandwidth modulator drivers, TIAs, CTLEs, filters, low noise and power amplifiers
- Experience working on wideband circuit designs supporting high speed Serdes links with more than 100Gbps data rate and BW exceeding 10s of GHz
- Familiarity with high speed SerDes architecture and modulation schemes such as NRZ/ PAM4 and link protocols
- Familiarity with optical and radio related test equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, high speed oscilloscopes and BERTs
- Experience characterizing EIC/PIC performance for high speed optical Serdes
