About the role
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! We are looking for a talented engineer to provide technical leadership to the Hardware Systems organization to help us build the next generation of silicon photonics based artificial intelligence accelerators and interconnect products. As a Hardware Systems Technical Lead, you will be responsible for delivering board and system solutions using Lightmatter’s innovative technology to create state of the art machine learning/artificial intelligence or massive scale-out interconnect platforms. You will work closely with our hardware and software teams, including mechanical, packaging, and IC engineering, to design and build leading edge system level products.
Responsibilities Collaborate with system architects and technical leads to define and develop hardware systems for photonic AI infrastructure applications Own hardware systems development throughout the full lifecycle, from concept through production Define, develop, and review PCBAs to meet system-level electrical, power, and interface
requirements Lead hands-on integration, verification, and validation across bench bring-up, EVT/DVT, and production release Drive cross-functional collaboration with firmware, photonics, packaging, and software teams to resolve dependencies and manage tradeoffs Maintain thorough hardware documentation for schematics, design reviews, test plans, validation reports, and other engineering documentation Research components and technologies to meet current and next-generation product goals and contribute to the technology roadmap, and improve development processes and engineering best practices Mentor and provide technical guidance to engineers on
