Principal Responsibilities

1. Failure Analysis & Root Cause Investigation
   • Perform detailed failure analysis investigations on fiber laser units and subsystems, including:
     • Optical components (fiber, collimators, isolators, lenses)
     • Laser diodes and pump modules
     • Power electronics and control boards
   • Apply structured root cause analysis methodologies (e.g., 5 Why, Fishbone, Fault Tree Analysis, DMAIC).
   • Conduct electrical, optical, mechanical, and thermal diagnostics to identify failure mechanisms.
   • Validate failure hypotheses through experimentation, testing, and data analysis.
2. Reporting & Documentation
   • Prepare clear, structured technical reports documenting:
     • Failure symptoms
     • Investigation methods
     • Root causes
     • Corrective and preventive actions (CAPA)
   • Present investigation findings and recommendations to engineering, quality,...
