1D Engine Simulation Engineer (GT-SUITE/GT-POWER)

General Motors; Pontiac, Northern (MI, KY); Hybrid; USD 90,000 - 130,000; Full time

Job summary

General Motors is seeking an Engine Performance Engineer to develop 1D engine simulation models in GT-POWER for diverse engine architectures, including gasoline and diesel. You will simulate full/part-load conditions, analyze lab data, and support control algorithm evaluation (HIL/SIL) and vehicle performance assessment.

The role requires a BS in Engineering/CS/Physics, 3–5 years in propulsion simulation, and strong communication skills. Hybrid work arrangement and relocation benefits may apply.

Qualifications

• Bachelor of Science in Engineering, Computer Science, or Physics.
• 3 years of propulsion simulation and/or virtual engineering experience.
• 5 years of engineering experience.
• Fundamental understanding of combustion engines and the modeling approach via GT-SUITE 1D CFD Software.
• Experience with engine dynamometer testing and data analysis.
• Excellent oral and written communication skills.
• High comfort with ambiguity, developing new capabilities, and creating new standard work.
• High level of interpersonal skills to work effectively with others.

Responsibilities

• Develop 1D engine simulation models in GT-POWER of a wide variety of engine architectures with complete intake and exhaust systems for both Gasoline & Diesel engines.
• Simulate full and part load models focusing on torque, power and fuel consumption.
• Process lab and model generated engine operating data (fuel mapping) into standardized format.
• Execute transient engine simulations to support engine control algorithm evaluation and/or development (HIL/SIL), and vehicle performance assessment.
• Create Medium or Fast Running Models (MRM / FRM) to support controls development activities.
• Develop new and innovative analytical techniques to model engine technologies (boost devices, exhaust gas recirculation, variable valve lift, emission control systems, aftertreatment etc.) with emphasis on minimizing test data requirements.
• Develop optimized valve lift profiles using parametric valvetrain design software.
• Provide component-level and/or system-level design recommendations to Design Responsible Engineers based on interpretation of analysis results.
• Participate in product design and development teams and regularly present analysis results to engineering peers and management.
• Appropriately distill 3D math data into 1D model geometry using the correct discretization techniques.
• Cooperatively work with test engineers to develop and/or enhance laboratory procedures to validate system analysis results.
• Contribute to the development of post-processing and automation tools using MATLAB and/or Python.
• Generate virtual data for or directly create calibrations for embedded engine controller.
