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! About this Role Join a cutting-edge team at the forefront of silicon photonics and high-speed transceiver design! As a member of the analog team, you’ll collaborate with our architects and engineers to develop innovative high-speed analog transceiver solutions for next-generation optical and wireline communication systems. We are currently hiring for multiple levels for this role. Your level and compensation will be determined by your experience, education, and location.
