The difference between a dev and an engineer is a bit semantic. I would say an engr has the additional task of being a leader, overseeing the project, and implementing the QA.

That said, no, it's not clearly defined, and there are dozens of not hundreds of different tasks a FED could have a role in. Graphical design, UI, UX, usability, SEO, and multimedia just to name a few.

Probably most critical though, a FED has to really keep up with emerging technologies. HTML5 didn't even exist a few years ago. Ajax is only 6ish years old. Flash is a necessary skill to help with IE's failings. And Flash != Flex != AS3.
