• Perform circuit and system-level analysis using suitable electrical simulation and engineering tools.
• Support DVP&R, DV/PV planning, validation testing, and interpretation of electrical test results.
• Analyze oscilloscope waveforms, current/voltage profiles, switching behavior, temperature rise, and electrical endurance results.
• Lead or support root-cause analysis for electrical/electronic failures and define corrective and preventive actions.
• Prepare technical analysis reports and correlate simulation, calculation, prototype, and test results.

5. Technical Documentation & Engineering Change

• Prepare and maintain electrical schematics, circuit calculations, BOMs, specifications, test requirements, and design reports.
• Prepare design review documents, DVP&R inputs, validation reports, and technical presentations.
• Ensure electrical design documentation is complete, accurate, and maintained under revision control.
• Support engineering change management, component changes, localization, alternate-source development, and product improvement.
• Support preparation of technical documentation for customer, supplier, APQP, audit, and compliance requirements.

6. Cross-Functional & Supplier Coordination

• Work closely with R&D, Application Engineering, Mechanical Design, Quality, Testing, Purchase, Manufacturing, and Sales teams.
• Coordinate with suppliers for electronic components, coils, sensors, connectors, PCB assemblies, and other electrical subassemblies.
• Participate in technical reviews, supplier development, design reviews, prototype builds, and customer project meetings.
• Support manufacturing and EOL test development for electrical/electronic product characteristics.
• Drive timely resolution of electrical design, prototype, validation, supplier, and production issues.

Required Skills & Qualifications:

• Strong understanding of HVDC contactors, BDU, PDU, EV battery systems, and high-voltage electrical architecture.
• Strong knowledge of DC switching, power electronics, coil drive circuits, transient suppression, electrical endurance, arc behavior, and current interruption.
