What you will do

• Develop, own, and execute validation for silicon photonics products, including PICs, EICs, optical subsystems, reference modules, and optical interconnect platforms.
• Build software and automated test environments to control VNAs, LCAs, AWGs, oscilloscopes, bit-error-rate testers, SMUs, and optical instrumentation.
• Characterize modulators, photodetectors, integrated lasers, optical engines, RF drivers, TIAs, ADCs, and DACs.
• Validate 100G/lane and 200G/lane PAM4 transmitters and receivers, including FRO, LRO, LPO, and NPO modules.
• Collect and analyze small-signal, large-signal, BER, and eye-diagram performance data, then prepare validation reports and recommendations.
• Collaborate with silicon photonics, RFIC, packaging and thermal, firmware, manufacturing test, NPI, and product engineering teams to support subsystem integration and technical problem-solving.

Requirements

• Bachelor’s degree with 4+ years of experience, Master’s degree with 3+ years, or PhD in Electrical Engineering or a related STEM field.
• 3+ years of hands-on experience testing and validating silicon photonics devices, RFICs, or optical communication subsystems.
• Experience with PICs, RF probes and probe stations, evaluation-board-based optical subsystems, and high-speed electrical and optical measurement equipment.
• Experience testing optoelectronic devices such as lasers, modulators, photodetectors, and optical interconnect technologies.
• Strong programming skills for instrument control, automation, and data processing, including Python and data analytics tools.
• Experience with VNA/LCA platforms, AWGs, DCAMs, high-speed oscilloscopes, optical test equipment, and RF probe calibration using calibration substrates.

Nice to have

• Experience with 100G/lane and 200G/lane PAM4 DSP, RF drivers, TIAs, microcontrollers, DACs, ADCs, power supplies, and SMUs.
• Experience with C++ or equivalent software platforms, optical transceiver testing, and calibration methodologies.
• Knowledge of optoelectronic device and RFIC physics, optical transceiver MSA requirements, and 800G/1.6T DR8, FR4, LPO, and LRO technologies.
• Experience using AI tools for code generation, debugging, and deployment.
