Job Purpose

Key Responsibilities
• Develop and maintain 1D engine and propulsion models in GT Power including complete intake and exhaust systems.
• Correlate models to test data (dyno/rig/vehicle) for torque, power, air mass, BSFC, temperatures, and pressures; document correlation quality and underlying assumptions.
• Simulate full load and part load operating maps, including steady state sweeps and transient maneuvers, to support performance, drivability, and thermal assessments.
• Perform DOE and optimization studies within GT Suite to explore design and calibration spaces (valve events, boost, turbo sizing, combustion and heat rejection levers, etc.).
• Translate 3D CFD and test insights into 1D model representations, including proper discretization of manifolds, ports, and system components, and appropriate use of loss and heat transfer models.
• Develop and improve standard methods and templates for GT Power model setup, correlation, FRM conversion, and coupled analyses (e.g., GT Power/Converge procedures).
• Process and structure large model and lab data sets into standardized formats for efficient post processing, visualization, and reporting.
• Provide design and calibration recommendations at component and system level (ie. induction, boosting, exhaust, valvetrain interfaces) based on model results and sensitivity analysis.
• Communicate results and trade offs through clear technical reports, presentations, and design reviews with hardware testing, mechanical simulation, calibration, and vehicle integration teams.
Required Qualifications
• Bachelor's degree in Mechanical, Automotive, Aerospace Engineering, or a related field
• 3+ years of experience in propulsion simulation, virtual engineering, or engine performance analysis, with a primary focus on GT SUITE / GT Power or similar 1D CFD tools (e.g., WAVE).
• Strong fundamental understanding of combustion engines, thermodynamics, fluid dynamics, and heat transfer, including how these are represented in 1D models.
• Demonstrated experience building, correlating, and evaluating 1D models used for hardware development, calibration, or vehicle performance prediction.
• Experience with engine dynamometer testing and data analysis
• Proficiency with data analysis and scripting tools (e.g. Python) for post processing, automation, and reporting.
• Excellent oral and written communication skills, with the ability to present complex modeling results to diverse technical and leadership audiences.
• High level of analytical ability, attention to detail, and comfort with ambiguity, especially when defining assumptions and interpreting results for new architectures.
Preferred Qualifications
• Master's degree or PhD in Mechanical, Automotive, or closely related field with emphasis on IC engines, thermodynamics, or fluid mechanics.
• 5+ years of experience with GT Power or similar 1D engine simulation tools, including advanced features (FRM, optimization, coupled models).
• Experience with engine calibration, controls, and model based calibration techniques
• Background in engine testing and development, including correlation of simulation to dyno and/or vehicle data for performance and drivability metrics.
• Familiarity with coupled 1D-3D CFD analyses (e.g., GT Power with STAR CCM+ or CONVERGE) for manifolds / ports.
• Experience establishing and maintaining standard work, templates, and training material for 1D simulation methods within a broader engineering community.
• High level of interpersonal skills and demonstrated ability to work effectively in cross functional, global teams (hardware, mechanical simulation, testing, calibration, thermal, vehicle integration).
