• Define integration strategies, test plans, test specifications, test cases, procedures, and test environments based on system architecture and requirements.
• Perform system integration testing across HIL, SIL, bench, and vehicle platforms.
• Validate interfaces between BMS controllers, cell monitoring units, sensors, contactors, thermal management systems, and Super Capacitor modules.
• Verify hardware, software, communication interfaces, diagnostics, safety mechanisms, and cybersecurity functions.
• Analyze test results, identify defects, perform root-cause analysis, and support issue resolution.
• Maintain bidirectional traceability between system requirements, test cases, test results, and defect reports.
• Support regression testing, change impact analysis, and release verification.
• Collaborate with software, hardware, validation, functional safety, and cybersecurity teams.
• Ensure compliance with Automotive SPICE SYS.4 work products, review processes, configuration management, and test evidence requirements.
