System Modeling Design Engineer - CA, San Jose, United States
Originally posted 28 September 2026 by the employer.
About the role
This role involves leading the development and application of advanced simulation frameworks for photonic device and system modeling.
What you'll do
- Lead photonic device and system modeling efforts to enable simulation-driven architecture definition and design decisions.
- Develop and apply SystemVerilog-based models for optical system-level simulation and co-verification with electronic subsystems.
- Perform time-domain modeling and simulation using Python and/or Julia for optical link performance, SerDes interactions, DSP algorithms, jitter, noise, and signal integrity.
- Build, validate, and maintain multi-physics models (optical, electrical, thermal) to predict behavior across operating conditions.
- Collaborate with cross-functional teams to ensure accurate co-modeling and robust system integration.
- Correlate simulation models with lab measurements, including high-speed link characterization and silicon or module-level test data.
What you'll need
- Extensive experience in photonic device and system modeling, simulation, and performance optimization.
- Hands-on expertise with industry-standard photonic simulation tools (e.g., Lumerical, VPIphotonics, OptiSystem, COMSOL, or equivalent).
- Experience with SystemVerilog and mixed-signal/system-level modeling frameworks for optical-electrical co-simulation and verification.
- Strong experience in time-domain simulation using Python and/or Julia, including modeling of high-speed optical links, SerDes behavior, and DSP algorithms.
- Proficiency in Python and/or Julia for building custom simulation frameworks, numerical analysis, data processing, and model automation.
- Deep understanding of multi-physics modeling, including optical, electrical, and thermal interactions.
- Proven ability to correlate simulation results with laboratory measurements, including high-speed link characterization and BER performance.
Nice to have
- PhD or Master’s degree in related discipline.
