WORK HISTORY
Calibration Triage Engineer @Stellantis
Auburn Hills, MI, US
Root cause analysis and triage for powertrain electrical and mechanical issues on pre-production Ramcharger (REEV) and Ram Electric (BEV) vehicles during prototype builds.Tested and validated key powertrain components including the engine, Integrated Dual Charging Module (IDCM), electric drive motors, battery pack, and Master ECU, ensuring seamless system integration and functionality.Performed module flashing and software validation to support calibration and diagnostic readiness across vehicle builds.Increased triage efficiency by 50%, improving throughput from one vehicle every two days to one vehicle per day through optimized workflows and data-driven troubleshooting.Collaborated with EE SWAT and cross-functional teams to diagnose and resolve non-powertrain electrical and software issues, contributing to full-vehicle validation.Utilized Vector CANalyzer, ETAS INCA, and OEM diagnostic tools for in-plant data acquisition, issue analysis, and propulsion system verification.
