Technical Specialist - Battery Algorithm Calibration

Job Description

Work Arrangement:

Hybrid: This role is categorized as hybrid. This means the successful candidate is expected to report to Milford, Michigan three times per week, at minimum.

The Role:

GM’s Vehicle Mechatronic Embedded Controls – Battery Systems Calibration group currently has an opening for a Technical Specialist – Battery State Estimation (BSE) Calibration. The position is located at the Milford Proving Grounds in a facility dedicated to Hybrid, Electric, and Autonomous Vehicle development.

The Technical Specialist – Battery State Estimation Calibration is responsible for leading a team of Calibration Engineers to produce high‑quality, on‑time deliverables for all Electrification vehicle programs using common methods, processes, and procedures. The selected candidate will also have a unique opportunity to influence and develop future Electrification architectures, with a focus on world‑class battery state estimation performance.

At General Motors, our product teams are redefining mobility. Through a human-centered design process, we create vehicles and experiences that are designed not just to be seen, but to be felt. We’re turning today’s impossible into tomorrow’s standard —from breakthrough hardware and battery systems to intuitive design, intelligent software, and next-generation safety and entertainment features.

Every day, our products move millions of people as we aim to make driving safer, smarter, and more connected, shaping the future of transportation on a global scale.

What You'll Do:

Technical Leadership – Battery State Estimation

• Serve as the technical leader for calibration direction of Battery State Estimation algorithms (SOC, SOH, power/energy limits, derating, protection thresholds, etc.) across all Electrification vehicle programs.

• Lead calibration strategy development for BSE and support associated controls development, ensuring alignment with system‑level energy, performance, durability, and safety objectives.

• Develop common, scalable approaches to BSE calibration and institutionalize them in Calibration Standard Work, including CEGs, DUCs, and Cal Planner content.

• Improve the efficiency and quality of BSE calibration by systematically driving vehicle‑based tasks into lab and/or math/virtual environments, maintaining strong correlation between virtual environments, test benches, and vehicle results.

Calibration Governance, Planning, and Standard Work

• Lead the Calibration Technical Review Board (TRB) for Battery State Estimation, including establishing and maintaining a dedicated Jira project space for the TRB.

• Define and continuously improve the calibration process for BSE and mentor new calibrators in its application. 

• Own and maintain BSE‑related standard work, including planning content and task flow from initial calibration through production using Cal Planner, Master Cal and Cal Check databases.

• Support Planning Studies and Workload Estimation.

Execution, Tools, and Methodology

• Create and maintain Calibration Execution Guides (CEGs) and Driver Use Cases (DUCs) specific to BSE behaviors, including variants for joint venture partners as needed.

• Create and maintain specific tools and work products to support the BSE calibration team (typing sheets, DMI files, CDI files, test scripts, instrumentation lists, and analysis utilities).

• Lead development of new methodologies to manage and model battery physics in the vehicle (e.g., cold‑temperature behavior, lithium plating risk, fast‑charge behavior, aging effects) and embed them in calibration standard work.

People Leadership and Mentoring

• Mentor Calibration Engineers, providing technical training and fostering strong communication and knowledge sharing within the BSE calibration community.

• Set up regular meetings with BSE calibrators and partner teams to review Cal Planner status, Master Cal metrics, issues, and lessons learned.

• Act as point‑of‑contact subject‑matter expert (SME) for Battery State Estimation calibration, representing the function in internal and external forums.

Cross‑Functional Collaboration and Issue Resolution

• Collaborate with controls, software, hardware, safety, and program teams to define requirements and assess the impact of changes on BSE calibration.

• Lead or support resolution of BSE‑related issues across development, validation, manufacturing, service, and field environments.

• Represent BSE calibration in program reviews, planning activities, and issue‑resolution forums, ensuring ca
