  • Familiarity with vehicle and/or industrial control systems


  • Communicate subsystem level design/ideas to internal/external customers
  • Evaluate and interpret customer product requirements
  • Develop product designs to meet customer needs
  • Map requirements onto existing designs and/or develop new designs as needed
  • Optimize designs via analytical, numerical and/or empirical assessments
  • Ensure product designs are met by creating mechanical, thermal, and electrical model/analysis
  • Produce and/or evaluate design solutions that improve cost, quality, delivery, and performance
  • Direct CAD designer to complete 3D models and drawings as necessary
  • Release drawings to support production, cost estimation and prototype quotes
  • Review CAD models/drawings at the component, subsystem, and system level to ensure their integrity
  • Use CAD modelling software to create components, assemblies, and engineering drawings for manufacturing
  • Conceptualize appropriate mechanical & electrical design including design for manufacture and assembly
  • Document final design upon the successful development of component and simple subsystem, which includes releasing the final technical specification, related design calculation, and design (manual or guideline)
  • Create and maintain Bill of Materials (BOM) along with all project documentation
  • Design and document solutions, within the scope of concepts, for components and modules, taking project guidelines (e.g., safety, quality, costs, weights, dates) into consideration
