Senior BMS Validation Engineer

Stellantis•Auburn Hills, MI

About The Position

The Senior Battery Management System (BMS) Validation Engineer is responsible for developing and executing validation activities to verify the performance, safety, and robustness of BMS software in electrified powertrains. This role supports the design and execution of validation strategies across multiple environments—including High Voltage HIL, battery test benches, and vehicle platforms—to ensure accurate verification of BMS functions related to battery hardware control (cells, modules, contactors, HV bus) as well as diagnostics and safety behavior. The engineer will evaluate system and software requirements for testability and completeness, define and execute appropriate test scenarios, and analyze system behavior to identify issues and support root cause investigation. Working cross-functionally with Battery Systems, Hardware, Controls, Software Development, Diagnostics, and Functional Safety teams, this role contributes to the execution of robust validation campaigns and ensures alignment with Stellantis BMS software specifications and high-voltage system requirements. The position also supports validation activities related to BMS integration into the vehicle, ensuring reliable operation and compliance across electrified powertrain architectures.

Responsibilities

Define and implement BMS software test requirements and validation setups in collaboration with BMS Software Release and Controls teams
Develop and execute validation test plans using High Voltage HIL, battery test benches, and vehicle platforms to verify BMS functionality and performance
Perform detailed troubleshooting and system-level testing of HV battery systems, including cells, modules, contactors, and HV bus components
Analyze test results, identify anomalies, and support root cause investigation for software and system-level issues
Collaborate with cross-functional teams and participate in design and software reviews (e.g., CDR) to ensure validation readiness and coverage
Support development and tracking of BMS validation timing plans, ensuring alignment with program milestones and release schedules
Partner with Diagnostics engineering to ensure proper validation of BMS diagnostic functions associated with HV components and subsystems
Contribute to validation of BMS functional behavior, supporting broader system-level testing across HV battery features
Support integration and validation of the BMS at system and vehicle level, ensuring proper interaction with battery hardware and vehicle systems
Provide clear and timely communication of validation status, technical issues, and test results to project stakeholders
