About the role

Key responsibilities & impact

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 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.
