There aren't any except the one that you and your partners start. About the only thing developer-employees can do is organize into teams and try to improve the group's situation through collective bargaining (i.e. let us have part of the profits or we all leave). Even then, if they are still focused on value creation rather than wrapping up the company's revenue and clients under their own umbrella like salespeople do, they won't build much leverage. This is why it is so important for developers and other value creators to be founders so that the value they create flows back to them.
