GM Performance Power Units - Concord, NCHiL Plant Modeling & Configuration Engineer - OnsiteJob SummaryGM Performance Power Units is seeking a highly motivated HiL Plant Modeling & Configuration Engineer to own development of the real-time power-unit plant models used to support testing and validation of Formula 1 control software. Based in Concord, North Carolina, this role offers a unique opportunity to contribute to a foundational area of our F1 program and join a world-class Electronics & Controls team.
The HiL Plant Modeling & Configuration Engineer will develop, integrate, correlate, and maintain the dynamic plant models required to operate the TAG-700 SECU in a closed-loop HiL environment. The primary scope covers the Formula 1 power unit, including the internal combustion engine, air path, fuel system, turbocharger, energy recovery system, hydraulics, gearbox, differential, electrical network, thermal systems, sensors, and actuators. Vehicle-side models will be integrated from the responsible simulation teams.
A key responsibility will be selecting model fidelity against the targeted control functions, required dynamic bandwidth, correlation accuracy, and real-time execution budget. The objective is a balanced simulation that captures the interactions needed to support closed-loop controls validation without unnecessary complexity.
Key ResponsibilitiesHiL Plant Modeling and Integration- Own development, integration, correlation, and maintenance of the real-time power-unit plant models required to operate the TAG-700 SECU in a closed-loop HiL environment.
- Work with simulation teams from GMPPU, GM Motorsports, and Cadillac F1 to create a modular representation of the ICE, air path, fuel system, turbocharger, ERS, electrical and thermal systems, gearbox, differential, sensors, actuators, and supporting interfaces, while integrating vehicle-side models from the responsible teams.
Model-Fidelity Strategy- Work with simulation teams from GMPPU, GM Motorsports, Cadillac F1, and subsystem subject-matter experts to select fidelity based on targeted control functions, required bandwidth, correlation accuracy, available data, and real-time execution budget.
- Convert detailed engineering models into efficient real-time representations, applying fidelity where it creates measurable controls-validation value.
Model Correlation and Validation- Validate plant models through correlation against dyno, component, track, and higher-fidelity simulation data.
- Define correlation criteria and document model assumptions, operating ranges, limitations, parameter sources, intended use cases, and validated operating envelope.
HiL Hardware and Real-Time Platform- Work with electrical engineers to specify, configure, commission, and optimize the SECU HiL platform.
- Develop detailed supplier requirements covering real-time processors, I/O, signal conditioning, actuator loads, communication interfaces, electrical fault insertion, controller power sequencing, and crankshaft and camshaft signal generation.
Real-Time Platform Performance- Monitor processor loading, execution timing, communication performance, and model stability to ensure efficient, deterministic, and reliable operation of the HiL environment.
Closed-Loop Test Support and Fault Simulation- Provide a representative and repeatable environment for controls and validation engineers to test TAG-700 software under normal operation, transients, operating limits, degraded modes, and sensor, actuator, electrical, or communication faults.
- Support reproduction of relevant dyno and track conditions; ownership of control-validation testing remains with the validation teams.
Automation and Configuration Management- Support automated testing by making plant parameters, operating conditions, faults, and measurement channels configurable within the HiL environment.
- Maintain plant models, parameters, I/O configurations, hardware mappings, and supporting utilities under structured version and configuration control.
Required Qualifications- Bachelor's or Master's degree in Mechanical, Electrical, Controls, Automotive, Aerospace, Mechatronics, or a related engineering discipline.
- Four or more years of experience developing and integrating dynamic-system models for closed-loop control applications. Experience with fixed-step real-time simulation is preferred; deployment of plant models to HiL platforms is highly desirable.
- Strong proficiency with MATLAB and Simulink for dynamic-system modeling, simulation, data analysis, and model integration.
- Experience developing and integrating multi-domain plant models for closed-loop control applications, with the ability to adapt models for fixed-step real-time execution.
- Practical understanding of fixed-step simulation, solver selection, task scheduling, model execution rates, numerical stability, state initialization, and deterministic real-time execution.
- Familiarity with dSPACE, Speedgoat, or a comparable real-time simulation platform.
- Working knowledge of internal combustion engines, hybrid powertrains, electric machines, driveline systems, sensors, actuators, and embedded controller interfaces.
- Experience using test data or higher-fidelity simulation results for model parameterization, correlation, and validation.
- Strong systems-level thinking, technical communication, problem-solving, and cross-functional collaboration skills.
Preferred Qualifications- Hands-on experience deploying and commissioning real-time plant models on HiL platforms for Formula 1, motorsport, hybrid powertrains, advanced automotive controls, aerospace propulsion, or another performance-critical system.
- Hands-on model-development experience in several power-unit domains, such as engine-speed dynamics, combustion torque, gas exchange, turbochargers, electric machines, inverters, batteries, thermal systems, hydraulics, or gearbox and driveline dynamics.
- Experience with Functional Mock-up Interface, Functional Mock-up Units, co-simulation, reduced-order modeling, surrogate modeling, or model exchange between simulation environments.
- Experience enabling automated test frameworks, fault injection, regression testing, and requirements-based validation through configurable HiL environments.
- Familiarity with Formula 1 power-unit architecture, TAG-700 hardware, motorsport data systems, and dyno or trackside development environments.
You'll play a pivotal role in ensuring the reliability and performance of a next-generation Formula 1 power unit. Our culture rewards precision, innovation, and the relentless pursuit of performance.
