About the role

  • Develop 1D engine simulation models in GT-POWER of a wide variety of engine architectures with complete intake and exhaust systems for both Gasoline & Diesel engines.
  • Simulate full and part load models focusing on torque, power and fuel consumption
  • Process lab and model generated engine operating data (fuel mapping) into standardized format
  • Execute transient engine simulations to support engine control algorithm evaluation and/or development (HIL/SIL), and vehicle performance assessment
  • Create Medium or Fast Running Models (MRM / FRM) to support controls development activities
  • Develop new and innovative analytical techniques to model engine technologies (boost devices, exhaust gas recirculation, variable valve lift, emission control systems, aftertreatment etc.) with emphasis on minimizing test data requirements
  • Develop optimized valve lift profiles using parametric valvetrain design software
  • Provide component-level and/or system-level design recommendations to Design Responsible Engineers based on interpretation of analysis results
  • Participate in product design and development teams and regularly present analysis results to engineering peers and management
  • Appropriately distill 3D math data into 1D model geometry using the correct discretization techniques
  • Cooperatively work with test engineers to develop and/or enhance laboratory procedures to validate system analysis results
  • Contribute to the development of post-processing and automation tools using MATLAB and/or Python
  • Generate virtual data for or directly create calibrations for embedded engine controller

Requirements

  • Bachelor of Science in Engineering, Computer Science, or Physics
  • 3 years of propulsion simulation and/or virtual engineering experience
  • 5 years of engineering experience
  • Fundamental understanding of combustion engines and the modeling approach via GT-SUITE 1D CFD Software
  • Experience with engine dynamometer testing and data analysis
  • Excellent oral and written communication skills
  • High comfort with ambiguity, developing new capabilities, and creating new standard work
  • High level of interpersonal skills to work effectively with others.
Benefits
  • From day one, we're looking out for your well-being–at work and at home–so you can focus on realizing your ambitions.
