• Enforce quality by helping define test cases with test team by providing detailed requirements and supporting documentation when needed
• Collaborate with platform software, validation, and analytics teams to implement and refine algorithms, and integrate feedback from field and lab data.
• Develop comprehensive test plans and perform thorough testing to validate firmware functionality, stability, and performance under various conditions.
• Extract and document detailed component-level requirements for battery management systems and power electronics, collaborating closely with cross-functional teams (hardware, firmware, systems engineering) to ensure alignment with overall vehicle objectives.
• Contribute to firmware, hardware, systems, and functional safety design reviews.
• Participate in functional safety and failure avoidance analysis of complex electrical and software vehicle subsystems (HARAs, FMEAs, etc.).
• Prepare technical reports and presentations to communicate findings to key stakeholders and management.
• Collaborate with mechanical, hardware and system team for seamless integration of hardware and software components.
• Act as the primary point of contact between the BMS software team and the battery pack team.
• Document integration and calibration processes, test results and system configurations
• Work with hardware and debuggers at a bench and HIL level to verify software operation.
• Instrument and profile software to identify opportunities for optimization on the submodule and system level.
