HVBD Calibration Engineering

Job Description

The Role:

VMEC (Vehicle Motion Embedded Controls) is hiring a Battery System Controls Calibration Engineer to join a productionfocused team that defines develops and improves calibration for control strategies diagnostics and controller communication on GMs electric vehicles.

In this role you will help turn advanced EV control designs into robust productionready calibrations using data from simulation lab and vehicle environments. You will work under general supervision collaborating closely with more senior calibrators and technical leaders while building deep expertise in highvoltage battery diagnostics.

You will partner with software scrums other calibration scrums system safety and validation teams on features spanning highvoltage automotive systems electric propulsion and battery charging helping ensure that software behaves safely intuitively and consistently for customers.

This space is rich with technical leadership opportunities from driving new calibration methods and virtual test capabilities to shaping how we execute. We are looking for creative highly motivated detailoriented calibrators who are comfortable working across multiple engineering disciplines and business partners can solve complex problems with datadriven rigor and thrive in a fastmoving environment where collaboration and continuous improvement are core to how we deliver.

What Youll do:

• Develop and maintain highvoltage battery diagnostic calibrations for GM electric vehicles including cell pack current temperature and controllerintegrity diagnostics owning welldefined calibration areas with guidance from senior calibrators.
• Implement and tune calibrations based on advanced EV control designs using data from simulation lab benches and vehicle testing following established calibration methods and standards.
• Execute validation activities for diagnostic performance and robustness across SIL HIL/ChIL battery lab and vehicle environments analyzing results to confirm requirements are met and escalating issues appropriately.
• Collaborate closely with software scrums other calibration scrums system safety and validation teams to ensure diagnostic calibrations align with feature intent safety goals and planned test coverage.
• Support calibrationdriven issue resolution by analyzing data reproducing issues proposing calibration changes and driving closure of assigned actions in support of launch quality and field reliability.
• Apply and help refine standard work (procedures test plans calibration rules and checks) so HV battery diagnostics remain consistent and scalable across EV programs and architectures; provide feedback and contribute updates in your areas.
• Manage calibration content for your features through GMs calibration tools and workflows (change management reviews and release processes) to ensure traceable highquality software deliveries.
• Use product health and field data (e.g. diagnostic metrics and robustness indicators) to monitor performance in the field identify trends in your ownership areas and recommend calibration improvements to reduce customerimpacting diagnostic issues.
• Demonstrate Level 6 behaviors by:
• Working under general supervision with limited daytoday direction while knowing when to seek guidance.
• Collaborating effectively with more senior team members and crossfunctional partners.
• Taking ownership of assigned work following through on difficult situations and contributing to continuous improvement within your immediate team.

Your Skills & Abilities (Required Qualifications)

• Bachelors degree in Electrical Engineering Mechanical Engineering Controls Computer Engineering or related field.
• 2 years of experience in automotive controls diagnostics or calibration (including onboard diagnostic calibration and/or integration); experience with EV / highvoltage battery systems preferred.
• Foundational experience with embedded controls and diagnostics for powertrain or EV systems (battery inverter charging or other safetycritical domains).
• Handson experience with calibration and data tools such as INCA Vehicle Spy MDA MATLAB/Simulink Python or similar including basic familiarity with calibration changemanagement workflows/tools.
• Familiarity with automotive communication protocols (e.g. CAN LIN FlexRay Ethernet).
• Demonstrated ability to:
• Analyze engineering and test data to diagnose issues and propose calibration adjustments within established guidelines.
• Apply company policies procedures and standard work to resolve a variety of issues in your area.

What Will Give You A Competitive Edge (Preferred Skills)

• Masters degree in relevant engineering discipline.
• Direct experience with highvoltage battery diagnostics (HVBD) or closely related EV diagnostic domains (e.g. contactor monitoring isolation diagnostics thermal diagnostics).
• Experience with GM calibration standard work and tools such as CalPlanner CalCheck CEGs JFTs and/or Jirabased workflows.
• Familiarity with virtual and labbased calibration methods (SIL HIL/ChIL CoSim Battery System Lab or equivalent).
• Demonstrated contributions to process improvement or method development within a calibration or diagnostics team (e.g. creating checklists simple automation scripts improved test procedures) consistent with Level 6 expectations for proactive problem solving within your immediate work area.
