About The Position

This role is for a Senior Sub-System Lead Engineer (SSLE) who 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 Motors’ most exciting features is a must! We are specifically hiring for the High Voltage Energy Transfer (HVET) / Charging area - focused on optimizing system operation to quickly align GM’s charging ecosystem and enable an enriching EV customer charging experience. For HVET – AC or DC - this includes establishing subsystem requirements for ensuring all vehicle side conditions are ready, maintaining stable power limits and temperature, managing the interface and communication, and terminating the charge session successfully. Additional requirements are for customer interactions, including displays, charge coupler, and mobile app. The role may also require a focus on development of requirements for Electric Vehicle state of charge, vehicle range, high voltage battery charging customer settings, etc.

Requirements

Bachelor’s Degree in Electrical, Computer Science, Mechanical, or related Engineering discipline
Minimum of 5+ years of experience in the field of expertise
Strong analytical problem-solving skills, including independent judgment and decision-making skills, where problems are very unusual and extremely difficult
Demonstrated communication and interpersonal skills required to build relationships with team members and customers to solve problems and resolve issues
Physics-based understanding of the Voice-of-Customer
Ability to effectively communicate issues, status, and recommendations to leadership
Proven ability in project management skills and ability to teach others
Ability to prioritize work with only limited direction from manager

Nice To Haves

Master’s or PhD in Engineering with an emphasis on Controls
8+ years of experience in the field of expertise
Experience or knowledge in NACS requirements, architecture, execution, and implementation, including handshaking and communications protocols, diagnostics, coupler technology, and Interoperability concerns and mitigations
Experience or knowledge in EV customer-facing charging system features including displays, back-office, charge port, and mobile apps
Experience leveraging simulation environments and plant modeling for testing or requirements generation is a plus (e.g., MATLAB/Simulink, D-Space HIL, SIL, ETAS Inca, etc.)
Experience with requirements management tools (e.g., DOORS, DNG, Markdown, etc.)
Experience with change management tools (e.g., Jira, GIT, IBM RTC, etc.)
Experience with Model Based Systems Engineering and associates SysML Tools (e.g., Rhapsody)
Experience with Scaled Agile Development (SAFe) process
Experience with OBD regulations requirements
Experience with safety critical systems (ISO-26262)

Responsibilities

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 applicable 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.
