  • Coordinate
    validation at NABL labs
    for AIS-156, AIS-038 Rev 2 compliance.
  • Analyze battery pack data for degradation, efficiency, and cycle life improvements.

Documentation & Cross-Functional Work

  • Prepare
    schematics, test reports, and BOMs.
  • Support
    vehicle integration
    , mechanical design, and homologation teams.
  • Manage
    supplier evaluation and sourcing
