System Validation Engineer

Job Title: System Validation Engineer
Location: Glendale, WI 53217 (100% On-site)

Role Description:

Develop, execute, and maintain system integration and system integration test activities for Lithium-Ion Battery Systems, Super Capacitor Modules (SCAP), and Battery Management Systems (BMS). Define system integration strategies, integration sequences, integration test plans, test specifications, test cases, test procedures, and test environments based on system architecture and system requirements. Verify integration of hardware, software, communication interfaces, diagnostics, safety mechanisms, and cybersecurity functions at the system level. Perform system integration testing on HIL, SIL, bench, and vehicle platforms. Validate interfaces between BMS controllers, cell monitoring units, sensors, contactors, thermal management systems, and Super Capacitor modules. Analyze test results, identify defects, perform root cause analysis, support issue resolution, and ensure closure of integration-related problems. Establish and maintain bidirectional traceability between system requirements, integration test cases, test results, and defect reports. Support regression testing, change impact analysis, and release verification activities. Collaborate with software, hardware, validation, functional safety, and cybersecurity teams to ensure successful system integration. Ensure Automotive SPICE SYS.4-compliant work products, reviews, configuration management, and test evidence for all integration deliverables.

Essential Skills:

Strong expertise in system integration and system integration testing for automotive ECUs, Battery Management Systems (BMS), Lithium-Ion Battery Systems, and Super Capacitor Modules. Strong knowledge of BMS functionality, including SOC, SOH, SOP, cell balancing, thermal management, contactor control, charging/discharging management, fault monitoring, diagnostics, and protection features. Experience in developing integration test plans, test specifications, test procedures, test execution, defect management, and test reporting. Hands-on experience with ASPICE SYS.4 work products and verification activities. Strong understanding of requirement traceability, test coverage analysis, defect lifecycle management, and issue investigation. Experience working with cross-functional hardware and software integration teams.

Desirable Skills:

Knowledge of ISO 26262 Functional Safety verification activities and safety mechanism validation. Exposure to ISO/SAE 21434 cybersecurity verification and security testing. Experience with low-voltage (12V/24V/48V) and high-voltage battery systems. Exposure to vehicle-level testing, battery validation, environmental testing, and Super Capacitor applications. Familiarity with AUTOSAR-based systems and electrification programs for automotive OEMs and Tier-1 suppliers.
