7d•Hybrid

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! As a Design for Test Engineer you will work closely with all disciplines involved in chip design and product operations to design, validate, and deploy test solutions for digital, analog, and photonic logic. You will be involved in a variety of tasks including logic design, validation and logic simulations, scripting, timing closure, post-silicon planning and bring up, and bringing products to market.
