Calibration Engineer High Voltage Battery Systems

Job Description

The Role:
VMEC (Vehicle Motion Embedded Controls) is hiring Battery System Controls Calibration Engineer to join a production-focused team that defines develops and continuously improves calibration for control strategies diagnostics and controller communication on GMs electric this role you will turn advanced EV control designs into robust production-ready calibrations using data from simulation lab and vehicle environments. You will partner closely with software scrums other calibration scrums system safety and validation teams on features spanning high-voltage automotive systems electric propulsion and battery charging ensuring 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 own high-voltage contactor control calibrations for GM electrified/Hybrid vehicles including contactor timing sequencing and protection/diagnostic strategies.
• Turn advanced EV control designs into robust production-ready calibrations using data from simulation lab benches and vehicle testing.
• Validate diagnostic performance and robustness across SIL HIL/ChIL battery lab and vehicle environments to minimize false alarms while protecting safety and hardware.
• Collaborate closely with software scrums other calibration scrums system safety and validation teams to ensure diagnostics align with feature intent safety goals and test coverage.
• Lead calibrationdriven issue resolution by analyzing data defining fixes and driving ontime closure to support launch quality and field reliability.
• Maintain and improve standard work (procedures test plans calibration rules and checks) so HV battery diagnostics are consistent and scalable across EV programs and architectures.
• Manage calibration content 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 identify trends refine calibrations and reduce customer-impacting diagnostic issues over time.

Your Skills & Abilities (Required Qualifications)

• Bachelors degree in Electrical Mechanical Controls Computer Engineering or a related field
• 02 years of experience (internships or projects included) in automotive controls diagnostics or calibration; exposure to EV or high-voltage systems is a plus
• Foundational understanding of embedded systems and diagnostics for vehicles (powertrain battery charging or related areas)
• Familiarity with common engineering tools such as MATLAB/Simulink Python INCA or Vehicle Spy through coursework or hands-on projects
• Basic knowledge of automotive communication protocols (CAN LIN Ethernet)
• Strong problem-solving skills with the ability to analyze data and support calibration or testing activities with guidance
• Good communication skills and ability to work with cross-functional teams (software systems validation etc.)
• Exposure to diagnostics or safety concepts (DTCs OBD or similar) through academic or project experience is a plus

What Will Give You A Competitive Edge (Preferred Skills)

• Masters degree in relevant engineering discipline.
• 5 years focused specifically on highvoltage battery diagnostics (HVBD) or closely related EV diagnostic domains.
• Experience with GM calibration standard work (CalPlanner CalCheck CEGs JFTs) Or Jira.
• Familiarity with virtual and labbased calibration methods (SIL HIL/ChIL CoSim BSL).
• Demonstrated impact in process improvement or method development (e.g. new robustness methods automation scripts or tools) within a calibration or diagnostics team.
