Ah, sure. Below are a handful (off the top of my head) that I admire:
Sal Soghoian: automation engineering expert "relieved" of duties for whatever reasons; consulting now I believe
Tony Fadell: went on to Nest, acquired by Google; not sure what he is doing now/next
Mike Matas: Omni Group, then co-launched Delicious Monster, then co-launched Nest with Tony Fadell after leaving Apple; I believe he is a UI designer now at Facebook.
Scott Forstall: controversial pick I'm sure, but early NeXT engineer, martyr of skeuomorphism; last seen producing a broadway musical or a play I think
Steve Jobs: 'nuff said.
John Callas: While typing this I just recalled that this famed cryptographer joined Apple sometime last year. If he is still at Apple, then I was admittedly off by one in my original statement ;-)
