Responsibilities
Design, develop, and productionize robust battery state estimation algorithms for SOC, SOH, and SOP using physics-based, model-based, and hybrid data-driven estimation techniques
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
Architect software with a focus on modularity, portability, and hardware abstraction, enabling reuse across multiple vehicle programs and evolving E/E architectures
Define and advocate calibration strategies and model-based approaches that reduce complexity while improving robustness and long-term maintainability
Lead shift-left verification, technical root-cause analysis and validation through MIL, SIL, and HIL test environments to enable early defect discovery and high validation coverage
Develop automated regression, robustness, and fault-injection test suites integrated into CI pipelines to enforce built-in quality throughout development
Collaborate cross-functionally with Cell and Pack Engineering, Systems & Functional Safety, Validation, Calibration, Vehicle Performance, SDV Platform and Research & Development teams
Mentor and guide other engineers, contribute to technical planning events, and help evolve GM’s battery estimation architecture as a scalable SDV service
Own deliverables end-to-end and continuously improving technical rigor, development efficiency, and software quality
