Senior Laser & SOA Characterization Engineer

We are hiring a senior engineer for our Photonics Characterization team at Lightmatter. Lightmatter is redefining computing by building photonic systems that use light to enable high-bandwidth, energy-efficient AI computing.

In this role, you will lead advanced characterization, bring-up, validation, and root-cause analysis of semiconductor lasers, tunable laser sources, DFB lasers, external-cavity lasers, laser diodes, and semiconductor optical amplifiers. This role requires strong hands-on lab expertise, deep understanding of laser physics and semiconductor device behavior, and the ability to connect measured device performance to design, packaging, system, and reliability implications.
