Electrical engineering occasionally relies on quantum mechanical properties of semiconductors and other materials in their products. Then again, EE is one of the hardest engineering disciplines (or so I hear).
In many cases, engineers can get by with relatively simple empirical models to describe devices that depend on quantum mechanics to actually work. (Case in point: permanent magnets, which, according to classical electrodynamics, really shouldn’t be able to exist.)
