Let me tell you what a UX developer is. UX developers are people that couldn't find themselves neither as designers or as developers and got stuck in between. Those became so many over the years; people interested not in being perfect at doing one thing, but at being intermediate in everything. Others are project managers who gained some experience in handling projects, but got bored of all the wire-framing, analysis and actually doing nothing (at least the majority), so they decided to get more involved in projects on a technical/creative level.
The first group, the stuck-in-between, become UX designers/developers with a few technical tricks. The second group, the managers, became UX analysts and experts.
So, in reality, your job as UX designer/developer, is to make real Designers dumb, by not letting them learn how to create usable designs, but designs that follow your lead and your wire-frames which eventually affect real Designers creativity. Or maybe real Designers are too dumb to learn how to offer the user a good experience! The UX developers, on the other hand, don't have an actual role. So if you're doing the wire-framing, the analysis, the content management, the information architecture, can you please specify what is a project manager doing? Plus, if your skills enables you to prototype certain features, what if you're involved in a super complex project, who's gonna prototype now? I know, the one who actually does the prototyping and is actually a real Programmer that knows his language very well and knows its actual limitations. Not the ones UX developers heard about.
The real definition for your job is ripped of from something every human should learn how to do and that's communication.
