Sr CAE Engineer - 1D Vehicle & Energy Management

We are seeking a highly skilled 1D vehicle system performance simulation engineer to join our team. The ideal candidate will possess expertise in applying 1D simulation tools to model, analyze, and optimize the performance of vehicle systems, supporting design, development, and validation of new and existing vehicle platforms.

• Develop and maintain high‑fidelity 1D simulation models of vehicle systems and subsystems (powertrain, chassis, thermal management, climate, electrical, vehicle systems control).
• Develop and maintain high‑fidelity 1D simulation models of vehicle attributes (NVH, vehicle dynamics, comfort, drivability, gradeability, vehicle acceleration, energy transfer, emissions).
• Utilize industry‑standard 1D simulation software (GT‑Power, AMESim, MATLAB/Simulink, Modelica) to conduct performance simulations.
• Analyze and interpret simulation results to identify potential issues, optimize system performance, and provide data‑driven design recommendations.
• Collaborate closely with systems engineers, designers, vehicle architects, validation engineers, and other cross‑functional teams to communicate simulation findings and insights.
• Correlate simulation models with physical test data to ensure model accuracy and improve prediction fidelity.
• Develop and implement thermal control strategies for optimal system performance and efficiency, especially for electric vehicle systems.
• Contribute to the continuous improvement of simulation methodologies and tools, developing innovative techniques and automating workflows.
• Prepare comprehensive technical reports and presentations to document and communicate analysis objectives, results, and conclusions.
• Stay current on advancements in simulation technologies and industry trends related to vehicle systems and performance.

• Bachelor’s degree or higher in Mechanical Engineering, Automotive Engineering, or a related field.
• Proven experience in 1D system modeling and simulation using GT‑Power and AMESim.
• Strong understanding of vehicle system dynamics, thermodynamics, fluid mechanics, and related areas.
• Proficiency in applying engineering principles and theory to solve complex technical problems.
• Experience using physical test data to correlate simulation models.
• Excellent analytical, problem‑solving, and critical thinking skills.
• Strong written and verbal communication skills with the ability to effectively present technical information to diverse audiences.
• Ability to work effectively in a fast‑paced, collaborative team environment.

• Master’s or PhD degree in a relevant engineering discipline.
• Experience with additional simulation software (MATLAB/Simulink, Modelica, Car Sim, mode Frontier, etc.).
• Familiarity with control engineering principles and their application in vehicle systems.
• Experience with software‑in‑the‑loop (SIL) or hardware‑in‑the‑loop (HIL) testing environments.
• Knowledge of relevant industry standards and regulations.
