Staff /Sr Staff Laser Module & Systems Characterization Engineer

Responsibilities

• Lead optical performance optimization (OPO) and initial bring-up for Guide TM 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.
