A power electronics research engineer helps to develop and test electronic technology and systems, such as computers, battery chargers, power converters, TVs, and radios that help control electric power conversion. As a research engineer, your duties and responsibilities are to assess projects, determine the cost of them, and to support other manufacturers or technicians as they assemble and test the performance of the components you have designed. You typically work closely with a team of researchers and engineers and report to a project manager.
