Simulation and Analysis Engineer

About the Role

Step into a state-of-the-art research and development organization dedicated to delivering high-tech transportation solutions to the North American market. As a Simulation and Analysis Engineer, you will shape the future of commercial transit across Diesel, Natural Gas, and Battery Electric Trucks. You will analyze complex thermo-mechanical systems, run full-vehicle simulations, and act as a technical leader. You will collaborate with cross-functional engineering teams—including Chassis, Cab, Electrical, and Testing—as well as Product Design to optimize exterior surfaces and meet strict functional and cooling requirements.

Responsibilities

• CFD Simulation & Thermal Management
  • Conduct comprehensive CFD analyses of individual components, sub-systems (e.g., heat exchangers, exhaust systems, air intake systems), and full-vehicle under-hood thermal simulations.
  • Interface with the Product Design team to evaluate exterior surfaces, providing feedback to improve airflow characteristics and minimize drag.
  • Perform validation studies comparing CFD results to experimental data, collaborating with global technical strategy teams to improve simulation workflows.
• Technical Leadership & Cross-Functional Collaboration
  • Post-process and analyze simulation results to write engineering reports and deliver actionable design recommendations that identify, rectify, and prevent potential flaws.
  • Partner with testing and project teams to develop test plans, establish instrumentation roadmaps, and interpret physical test data to anchor models.
  • Drive design solutions from concept to final production, maintaining ownership of the analysis until an acceptable outcome is achieved for all stakeholders.

Requirements

• Education: Bachelor’s Degree in Mechanical or Aerospace Engineering.
• Experience: Minimum of 5 years of dedicated experience in Computational Fluid Dynamics (CFD). A proven track record of validating and optimizing vehicle designs through CAE simulation tools is required.
• Industry Focus: Direct experience in automotive cooling airflow, thermal management, and aerodynamics is highly desirable.

Skills

• CFD & Thermal Software: 5+ years of hands-on experience with commercial CFD software such as PowerFLOW, Star-CCM+, or Fluent, alongside thermal analysis tools like TAITherm.
• Pre-Processing: Strong geometry cleanup skills using commercial CAE pre-processing software (e.g., ANSA, HyperMesh) to build fully detailed, complex CFD models.
• 1D Simulation: Familiarity with 1D simulation tools (e.g., GT-SUITE, KULI, Amesim, MATLAB/Simulink) for flow calculations, particularly running coupled 1D/CFD co-simulations, is a strong advantage.
• Infrastructure: Highly experienced working within a Linux OS environment and utilizing HPC (High-Performance Computing) systems to submit and monitor large-scale CAE jobs. Shell/Linux scripting skills for automation are a plus.
• Testing Knowledge: Practical, hands-on experience with validation, experimental measurements, and Design of Experiments (DoE).
• Core Engineering Fundamentals: Deep understanding of fluid dynamics, heat transfer, and thermodynamics. Strong synthesis skills to form clear, actionable recommendations from simulation, testing, and historical data.
