In applied areas like engineering, a year or two of industrial experience will not hurt your CV -- but it certainly will not be a key item there. 

In pure sciences (mathematics, physics, astronomy), this may be more like waste of time.

No rule is without exceptions, of course. If you spend a year or two at a research unit of some highly advanced and renown company -- then this may look good in the eyes of the people from academia. The general rule, however, is simple (at least in the West): if you are building an academic career, then stay in academia and don't leave.
