Develop, maintain, and apply system-level and component-level simulation models to evaluate performance, efficiency, energy consumption, thermal behavior, controls, and operating limits across drive cycles and vehicle platforms; perform sensitivity analyses and trade studies, correlate models with test data, and use results to guide requirements, architecture, calibration, and design decisions. The ideal candidate will possess a mechanical or electrical engineering degree and have a minimum of 5 years work experience in a development and testing environment, with practical experience related to hybrid and electric powertrain systems, simulation software tools, and electric motors/generators.
