Job Purpose
We are seeking a skilled Contingent 1D Simulation Engineer to join our team. As a key member of our engineering team, you will be responsible for developing and maintaining 1D engine and propulsion models in GT Power, including complete intake and exhaust systems.
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)
