It's really not, though (at least in the US). In just about every engineering subdiscipline except Civil/Structural, you can rise arbitrarily high in your career with no formal licensure or certification beyond a university degree and work experience. Official licensure schemes do technically exist for other subdisciplines, such as Mechanical, but I'm really not sure why. I've never met anybody who bothered to get one.
