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! Staff Electrical Design Engineer We are looking for a Senior Electrical Design Engineer to contribute to the development of the next generation of silicon photonics based artificial intelligence accelerators and interconnect products. In this role, you will lead board and system solutions that leverage Lightmatter’s technology to enable advanced machine learning, artificial intelligence, and large-scale interconnect platforms. You will lead and own HW systems efforts, collaborate closely with teams across hardware and software, including mechanical, packaging, and IC engineering, to design, integrate, troubleshoot and release system-level products at the leading edge of innovation.
Responsibilities Collaborate with the system architect and technical leads to define system-level hardware
requirements and spec Electrical design of power, memory, and interconnect circuits, working in both the analog and digital domains Identify electrical and optical components to fit the application based on specifications provided by the IC and photonics engineering teams Starting from fundamental concepts and system considerations you will develop conceptual designs, physical modeling, and simulations of chip-modules and systems Oversee and review PCB layout designs, providing complete and detailed electrical constraint rules Ensure the board and system is manufacturable to the latest technologies with high yield and robustness Qualification of chip and system electrical properties Perform laboratory validation of boards and systems Lead integration with mechanical, software, IC, and other related teams Support contract manufacturing during prototype and production phase to resolve any issues Work with component vendors and other supply partners Research new components, processes, and technologies to meet product goals
