Original job description

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.
