Full Job Posting
What You’ll Do
- 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.
- Your Skills & Abilities (Required Qualifications):
- Bachelor’s degree in Electrical, Mechanical, Chemical, or Computer Engineering, or Computer Science.
- Minimum 5 years of experience delivering embedded software for high‐voltage battery systems or similar complex engineering systems.
- Strong proficiency in C/C++ for embedded systems development.
- Demonstrated hands‐on production experience with SOC, SOH, and/or SOP estimation algorithms deployed in vehicles.
- Strong proficiency in MATLAB/Simulink and Python, with hands-on experience in modeling, analysis, automation, and Model-Based Development (MBD) workflows.
- Demonstrated success executing software and controls feature verification in MIL, SIL, and HIL environments.
- Experience working in Agile/Scrum environments and cross‐functional automotive programs.
- Proven ability to operate effectively in ambiguous, fast‐paced SDV development contexts with strong technical ownership and accountability.
- Proven experience leveraging Battery Data to generate actionable insights that improve battery performance, reliability, and lifecycle characteristics.
- What Will Give You a Competitive Edge (Preferred Qualifications):
- Master’s or PhD degree in Engineering or Computer Science.
- Deep expertise in battery modeling and estimation techniques, including observer design and Kalman filter–based approaches.
- 8+ years of experience delivering embedded software for high‐voltage battery systems or similar complex engineering systems.
- Hands‐on experience with battery cell characterization, pack testing, and lab‐based validation.
- Familiarity with lithium‐ion chemistries such as LFP and high‐nickel NMC/LMR and associated aging mechanisms.
- Experience with ETAS INCA, MDA, or similar calibration and measurement tools.
- Experience working within Software‐Defined Vehicle (SDV) architectures and CI/CD‐based software delivery pipelines.
