I read most of it, but you really lost me in the first sentence. If you are actually the CEO, that's one thing, but one sure fire way to piss off the engineers is to think of yourself as "the boss" simply because your role has "manager" in the title. Everywhere I've worked, the engineers answer to an engineering manager, and the engineering manager is a peer to the PM.
