Principal Silicon Photonics Design Engineer

Global Foundries

About the Role We are seeking a Senior Silicon Photonics Design Engineer to lead the design, simulation, and verification of advanced silicon photonic integrated circuits (PICs) for high-speed optical communication and computing applications. This role is ideal for an experienced engineer who combines deep theoretical knowledge with strong hands-on design and tape-out experience. You will work closely with cross-functional teams including process, layout, testing, electronics, and system engineers to deliver high-performance, scalable photonic solutions. Key Responsibilities: * Lead the architecture, design, and optimization of silicon photonic building blocks and subsystems (Tx/Rx). * Design and analyze components such as modulators (MRM, MZI), photodetectors, waveguides, couplers, splitters, and heaters. * Perform optical, electrical, and thermal simulations using industry-standard tools. * Drive PDK evaluation, design rule compliance, and layout-aware optimization. * Support chip tape-out, lab characterization, and correlation between simulation and measurement. * Own design documentation, specifications, and design reviews. * Mentor junior engineers and contribute to best-practice design methodologies. * Collaborate with system, packaging, and test teams to ensure end-to-end performance.
