Work Arrangement :
Hybrid: Position does not require an employee to be on-site full-time but the general expectation is that the employee be onsite an average of three (3) days each week.
VMEC, Vehicle Mechatronics Embedded Controls, is a production level group that supports the definition, design, and development of all embedded controllers that impact vehicle motion. The Sub-System Lead Engineer (SSLE) is an individual contributor with recognized expertise responsible for tasks and work throughout the entire vehicle development lifecycle, including requirements definition, design and implementation, testing, and problem resolution. Agile, systems engineering, requirements and embedded controls development, and calibration knowledge are a definite plus. The drive and tenacity to grow technically and professionally while working on some of General Motor's most exciting features is a must!
We are specifically hiring for Electrification Propulsion Controls area - focused on optimizing system operation to maximize range and drivability of electrified vehicles. Including online optimization of torque splits on dual axles of Electric and Hybrid vehicles, selecting/stabilizing engine and transmission states using open and closed loop torque distribution strategies, battery power management and regenerative braking to maximize energy efficiency while controlling battery state of charge. Additional challenges require applying control theory to prevent or remove disturbances (bumps, clunks, shuddering, etc.) from the driveline.
What You'll Do:
Lead complex sub-system analysis to define functional controls and requirements, including I/O Interface requirements (e.g., mapping, performance, transfer functions, safety, regulatory, etc.), while applying Behavioral Driven Development (BDD) principles.
Leverage physical (Vehicles and benches) and virtual (Models and simulations) to establish test cases and acceptance criteria for normal and degraded states of applicable sub-systems.
Create and maintain Sub-System Technical Specification (SSTS) and Behavioral Test Specifications (BTS) documents for applicable subsystems.
Create and maintain sub-system specifications in requirements management software (e.g., Doors, DNG, Markdown, etc.), including Functional Architecture Documents (FADs), and Context Diagrams with the assistance of Global Architecture teams.
Lead the root cause analysis for all appliable sub-system related issues and translate solutions into new or revised requirements.
Lead sub-system level FMEAs and collaborate on System and Component FMEAs and manage FMEA processes across applicable subsystems.
Collaborate with Controls and Software Engineers to review software implementation, ensuring compliance with requirements, and creating/executing Features/Stories in Jira to manage sub-system requirements and specifications.
