Staff /Sr Staff Laser Module & Systems Characterization Engineer

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.

You will work closely with controls engineers, photonics engineers, and the production team to translate module performance specifications into reproducible, manufacturable results. This is an individual-contributor role with direct ownership of test plan development, characterization, bring-up and validation execution , and the data that drives module specifications. This role requires strong laboratory experience in integrated photonics and fiber optics, as well as expertise in photonics and electronics testing, and data analysis. Analytical skills, problem-solving, and the ability to clearly communicate and document your findings are essential.

• Lead optical performance optimization (OPO) and initial bring-up for Guide ™ Laser modules; define and execute bring-up sequences from unpowered to full operating condition.
• Develop and own the bringup-to-eVT hand-off package: measurement summary, pass/fail criteria, and known-good reference data.
• Own characterization campaigns involving Guide and Passage based optical links, including end-to-end link validation, channel optimization, and margin verification through the lens of Laser/Guide systems. Identify and operate to resolve link-level anomalies; close the loop with module-level root-cause analysis.
• Develop structured manufacturing and characterization test plans aligned to photonics-control specs; define measurement protocols, calibration sequences, and acceptance criteria. Collaborate with control engineers to ensure test plan data supports algorithm validation and production deployment.
• Write and maintain Python or MATLAB measurement automation scripts for optical, electrical, and thermal test sequences; build data pipelines to surface yield signatures and process trends.
• Author clear characterization reports capturing methodology, results, and recommendations; communicate findings to cross-functional stakeholders.
• Partner with the team on laser-safety interlock validation and controller characterization flows.
• Interface with production on test plan deployment, NPI transitions, and manufacturing scale-up.
• Experience with high-speed and optical link characterization methodologies is a plus.
