Vacancy Status:Job DescriptionVacancy Status:Yes - This posting is for an existing vacancy within the organization and is open to new applications. (Backfill)AI DisclosureAs part of the application process, Artificial Intelligence will be used in the hiring process for this roleHybridThis role is categorized as hybrid. This means the successful candidate is expected to report to Markham three times per week, at minimum (or other frequency dictated by the business).The roleGeneral Motors is seeking an experienced System Architect to define the technical vision, architecture, and roadmap for hardware-in-the-loop (HIL) simulation environments supporting brake, chassis, and propulsion thermal management systems. These environments connect real-time plant models with embedded controllers, sensors, actuators, vehicle networks, and representative vehicle or subsystem hardware. They enable engineering teams to develop, integrate, verify, validate, and calibrate vehicle controls more safely, efficiently, and earlier in the product-development cycle. This is a senior technical leadership role for an architect who can operate across controls, software, hardware, modeling, test, safety, and program organizations. You will be recognized as a technical authority in your area, lead complex initiatives with broad visibility, and influence decisions across GM without relying on formal authority.What you’ll doDefine and communicate the architecture vision and multi-year roadmap for Brake and Thermal HIL capabilities, aligned with vehicle program, safety, quality, and functional objectives.Define requirements and acceptance criteria for model fidelity, deterministic real-time execution, latency, scalability and maintainability.Provide technical direction for real-time plant-model strategies covering brake hydraulics and actuators, chassis dynamics, vehicle motion, suspension-related behavior, thermal loops, pumps, valves, heat exchangers, radiators, battery thermal management, refrigerant, HVAC, and heat-pump systems, as applicable.Guide integration of models and HIL environments with embedded controllers, control software, calibration tools,



vehicle and subsystem hardware, electrical interfaces, and CAN, CAN FD, LIN, and automotive Ethernet networks.Lead resolution of the most difficult technical issues spanning modeling, controls, embedded software, communications, electrical and mechanical interfaces, real-time platforms, laboratory apparatus.Partner with product management, software teams, hardware design-release teams and test users to ensure that delivered environments are fit for purpose.Improve the robustness, usability, maintainability, documentation, operational readiness, and safe use of HIL benches and supporting assets.Lead large, ambiguous, and technically challenging initiatives across multiple engineering disciplines and organizational boundaries.Mentor engineers, grow technical capability across the organization, and promote knowledge sharing and reuse.What you’ll needBachelor’s degree in Mechanical Engineering, Electrical Engineering, Mechatronics, Aerospace Engineering, Computer Engineering, Software Engineering, or a related discipline.Typically 10 or more years of relevant engineering experience, including substantial experience with HIL, real-time simulation, embedded controls, or complex mechatronic test environments.Recognized expertise in one or more of the following: brake controls, chassis controls, propulsion thermal management, real-time simulation, HIL architecture.Demonstrated experience defining architecture, technical roadmaps, system interfaces, non-functional requirements, acceptance criteria, and verification and validation strategies for complex engineering solutions.Demonstrated success leading large, ambiguous,



and technically difficult initiatives across multiple disciplines and organizational boundaries.Strong experience with MATLAB/Simulink and real-time simulation platforms such as d SPACE SCALEXIO.Strong understanding of plant-model development, calibration, model correlation, real-time execution, closed-loop simulation, and integration with embedded controllers and representative hardware.Working knowledge of automotive communication technologies, including CAN/CAN FD, LIN, automotive Ethernet, and related engineering tools.Familiarity with system safety, functional taxonomy and control architecture.Experience with programming or automation using Python, MATLAB, C/C++, or equivalent languages.Excellent written, verbal, and executive communication skills, with the ability to influence technical direction across teams.Preferred QualificationsMaster’s degree in an engineering or computer-science discipline.Experience with brake-by-wire, electro-hydraulic braking, chassis motion controls, suspension, trailering, vehicle dynamics, or integrated chassis-control systems.Experience with coolant-loop, battery, refrigerant, HVAC, heat-pump, or propulsion thermal-control systems.Experience with Car Sim, GT-SUITE, Amesim, or other vehicle-dynamics and thermal-simulation tools.Experience with CANoe, CANalyzer, Vehicle Spy, ETAS INCA, Lauterbach, Control Desk, or comparable HIL and calibration tools.Familiarity with SAFe, Agile Release Trains, solution planning, or comparable scaled product-development practices.Experience with supplier technical management, budget or capital planning, or production vehicle program execution.CompensationThe salary range for this role is $147,000 to $196,600. The actual base salary a successful candidate will be offered within this range will vary based on factors relevant to the position.GM DOES NOT PROVIDE IMMIGRATION-RELATED SPONSORSHIP FOR THIS ROLE.
