Job Description

The Diesel Engine Performance & Aftertreatment Modeling Engineer in this role will:
- Develop and apply high-fidelity 1D engine simulation models (e.g., GT-SUITE or equivalent) to predict and optimize diesel engine performance (& gasoline), fuel efficiency, and emissions across the full operating range.
- Perform detailed airpath modeling and analysis, including turbocharger matching and control, charge air coolers, EGR systems, and EGR coolers, to support system-level design and optimization decisions.
- Develop and calibrate combustion, flow & heat transfer models, including both predictive (e.g., DI-Pulse, multi-zone) and prescribed (e.g., Wiebe-based) combustion approaches, to accurately represent in-cylinder processes and support combustion system development.
- Model and simulate aftertreatment systems and devices, including TWC, DOC, DPF, and SCR, to evaluate emissions compliance strategies and support aftertreatment system sizing and calibration.
- Correlate simulation models against dynamometer and vehicle test data, ensuring model accuracy and reliability across steady-state and transient conditions.
- Collaborate cross-functionally with hardware, calibration, and controls teams to translate simulation insights into actionable design and development recommendations.
