  • Implement control algorithms in embedded system controllers in accordance with applicable standards
  • Verify and validate code at SIL and HIL levels
  • Create and implement calibration and test plans
  • Analysis and specification of electro-mechanical and electro-hydraulic actuators
  • Confer with engineers and other personnel to implement operating procedures, resolve system malfunctions, and provide technical information
  • Research and analyze customer design proposals, specifications, manuals, and other data to evaluate the feasibility, cost, and maintenance requirements of designs or applications
  • Specify system components or direct modification of products to ensure conformance with engineering design and performance specifications
  • Embedded Control Systems Development: Follow standard software development practices for embedded control software development, including: requirements analysis, system design, architecture design, coding, integration testing, system testing, and acceptance testing
  • Create Software Requirements Specification documentation
  • Complete powertrain system-level FMEA
  • Create vehicle powertrain simulations for control system development and performance testing using AVL CRUISE and Matlab/Simulink
  • Create simulation test plans to characterize expected vehicle performance and for powertrain control system development & verification
  • Develop and implement powertrain supervisory control algorithms in the simulation environment
  • Integrate pre-existing algorithms for vehicle control into new implementations in Simulink using MotoHawk toolchain
  • Execute simulation test plans and generate complete and concise reports and presentations of results
  • Implement and test fault-management algorithms in Simulink using MotoHawk toolchain
  • Work with vendors and create communications interfaces via CAN and direct interfaces using MotoHawk toolchain
  • Select appropriate control hardware based on system requirements
  • Create point-to-point wiring diagrams from control system design requirements
  • Implement completed control software applications onto physical systems
  • Create and execute calibration test plans to calibrate embedded code on physical system
  • Track and document sub-project status and milestones to meet overall timeline
  • Participate in recurring project meetings to update team on sub-project status, issues, goals etc.
  • Provide formal reports, documentation and presentations for milestone specific events


  • Strong verbal and written communication skills
  • Excellent problem solving and time management skills
  • Good aptitude and knowledge of feedback control systems
  • Extensive experience with Matlab and Simulink
  • Knowledge of electronic equipment and computer hardware and software
  • Self motivated and highly organized
  • Background in automotive engineering and hybrid control systems
  • Experience in developing transmission systems or components highly desirable


  • Required: Bachelor’s Degree in Engineering
  • Highly Desired: Master’s Degree in Engineering
  • 5+ years experience in control systems
  • Matlab and Simulink
  • Experience with MCS Woodward (Mototron) toolchain desired


  • Up to 20% travel for on-site customer support at various US and world locations

The position is expected to have limited travel to visit current and potential suppliers and customers, both domestic and international. The position is expected to access, enter, and retrieve data by using a computer terminal. The position is expected to require hands-on management/use of laboratory test and production equipment. Some lifting of test equipment and battery modules will be required.
