Sub-System Lead Engineer – Electric Power Components

generalmotors; Warren (MI); On-site; USD 120,000 - 180,000; Full time

Job summary

General Motors is seeking a Senior Sub-System Lead Engineer (SSLE) for Electric Power Components to own the requirements and integration strategy for assigned power subsystems. You will translate customer and vehicle needs into robust, verifiable requirements and guide hardware, software, and diagnostics teams toward an integrated solution.

You will collaborate with Design Release Engineers, architects, safety engineers, controls, software, validation, and suppliers to ensure interfaces,

Responsibilities

• Lead the definition and maintenance of subsystem requirements for lead-acid batteries, intelligent battery sensors, DC/AC inverters, generators, and related Electric Power interfaces.
• Develop and maintain Sub-System Technical Specifications and, where applicable, Behavioral Technical Specifications, interface requirements, diagnostic requirements, and acceptance criteria.
• Decompose system and vehicle requirements into clear, complete, consistent, feasible, and verifiable subsystem requirements with full traceability.
• Maintain requirements and interface content in the approved requirements-management environment, including DOORS/DNG or successor tools, and ensure changes are controlled and communicated.
• Develop or contribute to Model-Based Systems Engineering artifacts, such as context, block definition, use-case, activity, and internal block diagrams, to clarify subsystem behavior and interfaces.
• Lead cross-functional requirement and behavior discussions, including triad reviews and Given/When/Then scenario development where applicable.
• Partner with Design Release Engineers and suppliers to ensure component designs, packaging, electrical interfaces, communication behavior, diagnostics, and performance meet subsystem intent.
• Collaborate with controls, software, diagnostics, calibration, and systems teams to review implementation, resolve integration gaps, and ensure hardware and software operate as an integrated solution.
• Define and maintain the validation intent for the subsystem, including testable scenarios, acceptance criteria, test coverage, and support for the Testable Functionality Roll-Out Plan.
• Coordinate with bench, vehicle, simulation, and virtual-validation teams to evaluate designs, investigate anomalies, and close issues using quantitative and qualitative evidence.
• Support development and maintenance of subsystem and solution FMEAs, including linkage to safety, manufacturing, service, and software-related failure modes.
• Support safety

Job description

Job Description

Our Mission: 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

The Sub-System Lead Engineer (SSLE) for Electric Power Components will lead the technical definition, integration, and validation of low-voltage electric power subsystems and their vehicle interfaces. The scope includes lead-acid batteries, intelligent battery sensors, DC/AC inverters, generators, and related power, communication, diagnostic, and control interfaces across current and future vehicle programs.

This role is accountable for translating vehicle and system needs into clear, testable subsystem requirements; maintaining alignment across hardware, software, controls, diagnostics, calibration, safety, validation, manufacturing, service, and suppliers; and driving timely resolution of complex technical issues. The SSLE will operate with a high level of independent judgment, influence technical direction across organizational boundaries, and lead work through collaboration rather than direct people management.

The Role

As a senior technical individual contributor, you will own the requirements and technical integration strategy for an assigned Electric Power subsystem or group of interfaces. You will connect customer and vehicle-level needs to component-level implementation and verification, ensuring that the resulting solution is robust, traceable, manufacturable, serviceable, and ready for program milestones.

You will work closely with Design Release Engineers, Functional System Architects, system and safety engineers, controls and software teams, technical specialists, validation teams, manufacturing, purchasing, service, and suppliers. You will also provide technical leadership to cross-functional teams and guide the work of other engineers as needed.

What You’ll Do

• Lead the definition and maintenance of subsystem requirements for lead-acid batteries, intelligent battery sensors, DC/AC inverters, generators, and related Electric Power interfaces.

• Develop, review, and maintain Sub-System Technical Specifications and, where applicable, Behavioral Technical Specifications, interface requirements, diagnostic requirements, and acceptance criteria.

• Decompose system and vehicle requirements into clear, complete, consistent, feasible, and verifiable subsystem requirements with full traceability.

• Maintain requirements and interface content in the approved requirements-management environment, including DOORS/DNG or successor tools, and ensure changes are controlled and communicated.
