• Develop schematics, review PCB layouts, and support hardware bring-up for high-voltage and high-current power conversion systems.
• Select, qualify, and validate power electronic components including IGBT modules, SiC devices, isolated gate drivers, current sensors, and power supplies.
• Develop and execute hardware validation plans including Double Pulse Testing (DPT), switching characterization, thermal testing, fault-condition testing, and commissioning activities.
• Analyze switching waveforms, gate signals, switching losses, current sharing, voltage overshoot, desaturation behavior, and protection circuit performance.
• Perform hands-on laboratory testing using oscilloscopes, differential probes, current probes, thermal cameras, power analyzers, and data acquisition systems.
• Investigate hardware failures and perform root cause analysis of inverter, gate driver, and power module issues including shoot-through events, false turn-on, over-voltage, over-current, and thermal failures.
• Correlate laboratory test results with simulations and analytical models to improve product performance and reliability.
• Collaborate with controls, validation, mechanical, manufacturing, PCB layout, and supplier teams throughout product development.
• Support prototype builds, production launches, supplier technical reviews, Design for Manufacturability (DFM), and Design for Testability (DFT) initiatives.
• Prepare technical documentation including validation reports, test procedures, engineering change documentation, and design review presentations.

Required Skills
