  • May coordinate the activities of junior test engineers or CM technicians, acting as Team Lead for tester bring-up and production readiness activities.
  • Drive completion of PFMEA and PPAP with main stakeholders, ensuring test coverage is aligned with quality gate requirements at each MLA milestone.
Issue Resolution and Root Cause Analysis
  • Independently identify, root cause, and track production test failures, working closely with Design Engineers to implement design changes during launch and early production.
  • Lead failure analysis of complex electronic module issues, applying in-depth evaluation of variable factors and exercising independent judgment in selecting investigation techniques.
  • Drive corrective action processes through to verified closure, maintaining strong documentation practices aligned with IATF/VDA quality system requirements.
  • Establish and monitor production testing KPIs (FPY, OEE, installed vs. planned capacity) and present findings to program leadership.

Qualifications
Experience
  • 6+ years of experience in the development, build, and commissioning of test equipment for electronic modules, including ICT, EOL testers, and programming stations - demonstrating wide-ranging expertise across multiple platforms or programs.
