Coming from the web world I find the term "back end developer" a heavily abused term. Most developers of web products would consider themselves back-end developers and typically program in either Java (or one of its variants) or C#. This isn't back-end merely because it isn't in a browser.

Your average web product Java developer is all middleware. They write code that gels between internal services and output to the user environment. At most large web companies real back-end teams are heavily isolated and don't let the middleware people come anywhere close to them even if they are all writing in the same language. If your web-product Java developer needs data they call to a service managed by an unrelated team.
