Summary

Job Summary

We are seeking a skilled Emissions and Simulation Engineer with expertise in 0D/1D CFD modeling and emissions systems. In this role, you will support the development and validation of powertrain and aftertreatment systems through simulation, with a focus on tailpipe (ATS) and evaporative emissions. The ideal candidate will have around 3 years of hands-on experience using GT-Suite, Exothermia, and/or GT-xCHEM, and will work closely with our engineering team to drive innovation in emissions reduction and system performance.
Key Responsibilities

Develop, calibrate, and validate 0D/1D CFD models for internal combustion engines, aftertreatment systems, and evaporative emission systems using GT-Suite, Exothermia, and/or GT-xCHEM.
Perform simulations to analyze tailpipe emissions (NOx, CO, HC, PM) and evaporative emissions, supporting compliance with regulatory standards.
Collaborate with cross-functional teams to integrate simulation results into powertrain design, calibration, and control strategies.
Support the development of aftertreatment system (ATS) models, including DOC, DPF, SCR, and ASC components.
Contribute to model-based calibration and optimization of engine and emissions control systems.
Prepare technical reports, documentation, and presentations to communicate findings and recommendations.
Stay updated with emerging simulation tools, regulatory requirements, and industry best practices in emissions engineering.

Qualifications & Experience

Bachelor's or Master's degree in Mechanical Engineering, Automotive Engineering, Chemical Engineering, or a related field.
Approximately 3 years of professional experience in 0D/1D CFD simulation and emissions analysis within the automotive or related industry.
Required Software Proficiency:
- GT-Suite
- Exothermia and/or GT-xCHEM
Strong understanding of:
- Aftertreatment systems (ATS) modeling and performance evaluation
- Evaporative emissions systems and modeling approaches
- Powertrain simulation and calibration processes
Familiarity with emissions regulations (e.g., EPA, Euro standards) and certification processes.
Experience with model calibration, validation, and correlation with test data.
Strong analytical, problem-solving, and communication skills.
Ability to work independently and collaboratively in a team environment.

Preferred Skills

Exposure to hybrid/electric vehicle powertrain simulation.
Knowledge of MATLAB/Simulink, Python, or other scripting tools for automation and data analysis.
Experience with 3D CFD tools (e.g., STAR-CCM+, CONVERGE) is a plus.
Understanding of control system development and hardware-in-the-loop (HIL) testing.
