To answer your questions, yes, Europe does hire Civilian Controllers, granted they are not in the hiring binge that the U.S. is but they are at least hiring.
My Fiance is German so I looked into possible going over to Europe to Start out.
The most notable one is
EuroControl, it is located in the south of Netherlands, near the German Border, it is kinda like the ARTCC of western europe. They have a little stricter requirement for age, but that is about all.
The other one I know specifically about is,
DFS, it is essentially the German FAA. Right now they are hiring a few inexperienced controllers, but mostly experienced controllers. Very similar requirements to the FAA, and the language is not an issue, you only need to be willing to learn German. They Pay a lot better too, and it is in Euros not Dollars.
In fact, it is pretty much a Universal is that you only have to be able to speak/read/write English, and be willing to
learn the host Country language. And most countries have no problem Hiring non-nationals.....for the most part, they are a little(A LOT) more generous than the U.S. on giving out work Visas.
