About The Position

Lightmatter is leading the revolution in AI data center infrastructure, enabling the next giant leaps in human progress. The company invented the world's first 3D-stacked photonics engine, Passage, capable of connecting thousands to millions of processors at the speed of light in extreme-scale data centers for the most advanced AI and HPC workloads. Lightmatter raised $400 million in its Series D round, reaching a valuation of $4.4 billion. We will continue to accelerate the development of data center photonics and grow every department at Lightmatter! If you're passionate about tackling complex challenges, making an impact, and being an expert in your craft, join our team of brilliant scientists, engineers, and accomplished industry leaders. Lightmatter is (re)inventing the future of computing with light! This role is for a Photonics Process Design Kit (PDK) Intern/Engineer responsible for developing and maintaining a PDK infrastructure for high-performance photonics integrated circuits (PICs). Key tasks include building PDKs for circuit layout and electrical-optical co-simulation, automating the workflow, and creating compact models for photonic devices based on characterization data. The role also involves interfacing the photonics design process with analog/mixed-signal (AMS) and digital verification teams for comprehensive optical link simulations.
