## About the role

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. We are looking for a Laser Characterization Engineer to join our Laser team. You will be the hands-on technical owner for bring-up, characterization, and validation of Lightmatter's laser modules and photonic systems — taking products from first-light through manufacturing qualification and production hand-off.

## What they're looking for

- BS + 8 years, MS + 6 years, or PhD + 3 years in Electrical Engineering, Physics, Optical Engineering, Photonics, or a closely related field
- Hands-on experience characterizing laser modules (DFB lasers, optical amplifiers, and other coherent sources) in a research or NPI environment with experience with DWDM optical link bring-up and validation as a plus
- Proficiency with core photonics lab equipment: optical spectrum analyzers (OSA), optical power meters, lightwave component analyzers (LCA), high-bandwidth oscilloscopes, and signal generators
- Experience building or executing structured test plans for optical or electro-optic assemblies — from test design through data delivery
- Proficiency with Python or MATLAB scripting for measurement automation and statistical data analysis
- Strong written communication skills, able to produce thorough, well-organized characterization reports
