A design engineer is a general term that covers multiple engineering disciplines including electrical, mechanical, chemical engineer, aeronautical engineer, civil, and structural /building/architectural..While industrial designers may be responsible for the conceptual aesthetic and ergonomic aspects of a design, the design engineer usually works with a team of engineers and other designers to develop conceptual and detailed designs. They may work with industrial designers and marketers to develop the product concept and specifications, and may direct the design effort. In many engineering areas, a distinction is made between the design engineer and the planning engineer in design; Analysis is important for planning engineers, while synthesis is more paramount for design engineers.
