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 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 clear technical communication abilities
Apply photonic modeling, analog circuit knowledge, Python, and silicon correlation to Lightmatter’s advanced optical platforms.
