Senior Silicon Photonics Laser Module Engineer

Lightmatter is redefining what computers and human beings are capable of by delivering a fundamentally new kind of computer that calculates using light. Transistors, the workhorse of modern computers, aren't improving at the rate they once were. To scale AI, companies are building increasingly large and energy-expensive data centers—a path that is neither financially nor environmentally sustainable. By delivering ultra-high performance and energy efficiency, Lightmatter’s compute engine will power rapid advancements in AI while lowering its environmental footprint.

LM is looking for a technical lead to drive Laser Module development required across multiple product lines for the company. As a technical leader, you will be leading a cross-functional team consisting of silicon photonics, analog, packaging and system engineers to drive various Laser Module development from concept to high volume production.
