Hybrid work position:

This position does not require an employee to be on-site full-time to perform most effectively.  The employee’s role enables them to work at a GM facility or off-site as frequently as needed or desired. In the USA, this is an employee who lives 100 miles or less from their designated, primary worksite.

This position requires an employee to be onsite every other week.

We are currently seeking experienced and motivated candidates for the role of SIL SIE (Software-in-the-Loop Simulation Integration Engineer) to support the Virtual Design Development Validation (VDDV) group. This role is part of a group responsible for creating virtual environments to enable calibration, verification, and validation of embedded controllers for engine, transmission, hybrid, electrification, chassis.

The Simulation Integration Engineer is responsible for leading the move to virtual engineering by leading the integration of full-vehicle cross-functional co-simulation packages that are used for all aspects of vehicle development.  This position involves high level of collaboration with teams throughout General Motors including VDDV, Vehicle Motion Embedded Controls (VMEC), Calibration, Algorithm, Vehicle Performance, Validation, and Hardware Development.  This position requires an individual with a passion for virtualization, an adept knowledge of hardware and software integrated systems, and a demonstrated capability to manage a wide variety of technical and customer needs.  He or she will work as a liaison between the Plant Modeling team, Tools team, and internal development teams, to integrate and deliver simulation environments on time and with quality. A balance of technical and project leadership skills and the ability to think outside the box to find simple yet exciting solutions is paramount.


  • Work closely with stakeholders to identify requirements, schedule, and deploy simulation projects  to enable virtual vehicle design, development, and validation

  • Engage with cross functional team members to coordinate on-time delivery of simulation components to meet requirements and timing

  • Integrate plant models and other ECU models with controller software source code and perform virtual system verification based on requirements

  • Obtain, develop, parameterize, and test virtual controller models to be used across different components such as HWIO, RTOS, controller I/O, and other ECU behavioral models

  • Perform simulation correlation activities based on experimental data

  • Create, maintain, and improve standard simulation architectures

  • Provide support for released simulations, including detailed documentation, and assist users with testing and troubleshooting

  • Design, develop, verify and execute automated test suites

  • Assist initiatives to benchmark and adopt next-generation simulation technology and tools

  • Identify, implement, and standardize new simulation development processes of engineering

  • Provide process and architecture feedback improvements

Additional Description



  • 2+ years of relevant experience.

  • Adept experience with MATLAB and Simulink in context of plant model development and integration and basic usage of additional simulation tools

  • Familiarity of additional simulation tools (e.g. GT Suite, GT Power, CarSim, Amesim, etc.)

  • Experience with embedded controls software and the automated software build processes, including familiarity with gcc compiler, gdb debugger, Eclipse, and ETAS INCA measurement and calibration tools

  • Familiarity with automotive communication technologies such as CAN, LIN, and SPI

  • Familiarity in computer programming languages including C/C++

  • Comfortable with leading large and/or difficult projects with high levels of ambiguity

  • Experience in leading large and/or difficult projects with high levels of ambiguity

  • Comprehensive vehicle propulsion system-level knowledge

  • Proven ability to work in teams, balancing technical theory with practical limitations.

  • Strong oral and written communication skills.


  • 5+ years of relevant experience.

  • Familiarity with version control systems (VCS) tools like Git, SVN and TFS.

  • Familiarity with simulation data management (SDM) systems like TeamCenter and RTC.

  • Familiarity with multibody and/or controls integration CAE tools such as GT Suite, ADAMS/MotionView, Carsim, Carmarker, MATLAB/Simulink or other similar CAE tools.


BS Mechanical Engineering, Electrical Engineering, Software Engineering, Computer Science, or Aerospace Engineering required.

MS Mechanical Engineering, Electrical Engineering, Software Engineering, Computer Science, or Aerospace Engineering preferred.

FOR GM INTERNAL CANDIDATES: This role is posted at both the 6th and 7th level. The determination by HR and the Hiring Manager as to whether an offer will be lateral or promotional will be based on a candidate’s relevant experience and whether the role will amount to a significant increase in level of responsibility.
