Senior Silicon Photonics Modeling Engineer

Model silicon photonic and analog circuits at Lightmatter in Mountain View, using Python, optical solvers, and Cadence in a hybrid workplace.As a Photonics Circuit Design Engineer, you will connect device physics with circuit-level behavior for Guide™ laser products and Passage™ optical links. You will create models covering active and passive photonic elements, analog interfaces, fabrication variation, dispersion, and thermal effects. Your work will support accurate end-to-end product simulations.Key Responsibilities:
Construct compact and behavioral models for silicon photonic elementsIncorporate process variation, dispersion, thermal, and nonlinear propertiesCalibrate parameters using optical solvers and silicon dataDeliver Guide laser and Passage interconnect sub-circuit simulationsValidate models against empirical silicon measurementsRequirements:
Ph.D. plus two years industry experience, or M.S. plus fiveDeep silicon photonic physics and analog circuit fundamentalsExperience with Lumerical, RSoft, Tidy3D, Cadence Virtuoso, and SpectreStrong Python skills for modeling and engineering codebasesAnalytical, methodical, and clear technical communication abilitiesApply photonic modeling, analog circuit knowledge, Python, and silicon correlation to Lightmatter’s advanced optical platforms.
