## About the Role

REQUIREMENTS: Bachelor's degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Computer Engineering, or related field of study and Five (5) years of experience as a Software Engineer, Design Engineer, Automotive Engineer, or related occupation. Two (2) years of experience with: Delivering embedded software for high voltage battery systems; SOC, SOH, and SOP estimation algorithms deployed in vehicles; C/C++ for embeddedsystems development; Agile/Scrum environments and cross functional automotive programs; and Leveraging Battery Data to generate actionable insights that improve batteryperformance, reliability, and lifecycle characteristics.

## Description

DUTIES: Design, develop, and productionize robust battery state estimation algorithms for SOC, SOH, and SOP using physicsbased, modelbased, and hybrid datadriven estimation techniques across multiple battery chemistries. Develop observers and filters (e.g., equivalent circuit and electrochemical informed models, Kalman filter based approaches) that remain accurate across temperature extremes, power transients, sensor noise, and battery aging. Incorporate calendar and cycle aging effects into estimation logic so outputs remain truthful throughout the battery lifecycle and across chemistries and pack architectures. Implement estimation algorithms as production quality embedded software in C/C++, meeting GM standards for safety, cybersecurity, and coding discipline, including MISRA compliance. 10% domestic travel required. Hybrid Work Policy - 3 days In-office, 2 days remote - Must be able to report to local office.
