Job Summary
:

You will plan, develop, and execute the verification and validation strategy for Battery Management System (BMS) firmware and hardware integration on a 400 V high-voltage battery program. Your role focuses on ensuring the BMS firmware is robust, safe, and meets all system requirements. This spans the entire validation spectrum, from Model-in-the-Loop (MiL) and Software-in-the-Loop (SiL) to deep, hands-on testing on Hardware-in-the-Loop (HiL) simulators.

Success in this role is measured by the reliability of the BMS when it lands on the vehicle. You will ensure 100% test coverage, establish automated regression pipelines, and provide the rigorous verification evidence required by ISO 26262. You will work as a core partner alongside BMS software developers, base software engineers, and systems engineers to catch defects early and clear the software for production release.
