The Technical Specialist will help drive how battery data is collected structured analyzed and used through the battery data pipeline to improve algorithm quality accelerate virtual validation strengthen in-field learning and support better engineering decisions across the battery organization and help ensure Battery State Estimation is ready for Software Defined Vehicle architectures by enabling scalable services better observability and faster learning through virtual and data-driven development.

The Technical Specialist (TS) works in close collaboration with fellow Technical Specialists across the same technical domain (e.g. calibration or software) and interfaces regularly with the Global Technical Specialist (GTS) for Battery State Estimation. The GTS serves as the enterprise technical authority and long-term domain leader. Technical Specialists are expected to represent their respective areas of responsibility in cross-functional workgroups ensuring alignment and comprehensive coverage across the Battery State Estimation domain.

What Youll Do:

• Lead technical development of Battery State Estimation features for high-voltage battery systems including state of charge state of health state of power energy and capacity estimation and related diagnostics.

• Define and evolve technical approaches that are scalable reusable and hardware-agnostic across battery systems vehicle programs and future software architectures.

• Build and execute technical plans that balance current production needs launch readiness and long-term capability development across multiple battery chemistries.

• Lead resolution of complex issues observed in vehicles benches and development environments using rigorous data-driven root cause analysis.

• Drive battery data analytics to improve understanding of battery behavior estimator performance degradation trends and field issues.

• Help define and mature the battery data pipeline so that test fleet and virtual data can be efficiently collected labeled analyzed and converted into actionable engineering insight.

• Use the battery data pipeline to improve algorithm development calibration decisions validation coverage virtual validation workflows and regression confidence.

• Partner with analytics validation calibration systems and battery engineering teams to build scalable data flows meaningful KPIs and high-value technical dashboards.

• Develop and deliver high-quality embedded controls software using strong software design principles traceability and production-ready engineering practices.

• Use automated testing in build environments benches virtual environments and vehicles to verify functionality at the controller system and vehicle levels.

• Apply model-based virtual validation and software-driven development approaches to improve built-in quality robustness and speed of learning.

• Work effectively with software-defined vehicle and service-oriented architecture concepts to help create modular maintainable and future-ready solutions.

• Partner closely with systems and safety validation calibration electrical architecture vehicle performance and battery engineering teams to deliver robust battery behavior in production vehicles.

• Develop maintain and continuously improve Software Execution Guidelines documentation while supporting and reinforcing a requirements-first approach within the Battery State Estimation (BSE) domain.

• Plan content facilitate discussions and distribute meeting minutes for recurring BSE Technical Workgroups and other relevant cross-functional forums.

• Mentor engineers guide technical reviews and help strengthen engineering capability across the team.

Your Skills & Abilities (Required Qualifications)

• Bachelors degree in Electrical Engineering Mechanical Engineering Chemical Engineering Computer Engineering Computer Science Controls Systems Engineering Data Science or a related technical field.

• 5 years in embedded controls software battery management systems high-voltage battery systems advanced state-estimation development or battery analytics.
