Ideal Candidate: The ideal candidate combines strong transistor-level high-speed IC design expertise with an understanding of optical communication systems. You should be comfortable treating the EIC, photonic IC, package, and optical link as a single system rather than independently optimized components. This position offers the opportunity to develop extremely low-power, high-bandwidth electronic-photonic interfaces for next-generation AI computing and data-center optical connectivity. Compensation
