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 elements Incorporate process variation, dispersion, thermal,



and nonlinear properties Calibrate parameters using optical solvers and silicon data Deliver Guide laser and Passage interconnect sub-circuit simulations Validate models against empirical silicon measurements Requirements:

Ph.D. plus two years industry experience, or M.S. plus five Deep silicon photonic physics and analog circuit fundamentals Experience with Lumerical, RSoft, Tidy3D, Cadence Virtuoso, and Spectre Strong Python skills for modeling and engineering codebases Analytical, methodical, and transparent technical communication abilities Apply photonic modeling, analog circuit knowledge, Python, and silicon correlation to Lightmatter’s advanced optical platforms.
