You probably know that new cars come out annually, and they're always smarter, more high-tech, better for the planet and, well, cooler than the previous year's models. As an automotive engineer, you'd be in the midst of this rather thrilling world. Your job would be broken into three parts: designing new components (like rear-view cameras or self-driving technology), fixing existing problems, and developing future products. Although "automotive" naturally suggests cars, these engineers work on other land-based vehicles as well, like tanks, trucks, and construction equipment. Only those obsessed with wheels need apply, and the best way to prep for this career is by getting a bachelor's degree in mechanical engineering. For people who know they want to work in this industry, some engineering schools offer specialized classes in automobile dynamics, engine parts, and alternative fuel sources.
