The Eurocontrol centre is located near Maastricht, the Netherlands.
Working language is English. If you look at their website the only language requirement for the job is to 'have a good command of English, the international language of aviation'.
Eurocontrol employs controllers from all over its member states, and most of them don't speak any Dutch when they apply. Everyday life is of course somewhat easier if you have/acquire some basic knowledge of the language, but then again many people around here speak/understand several other languages.
Edit: Since Dutch is my mother tongue I may not be your best source of information if you need to know about possible language problems ...
