I know this is an old thread, but the job opportunities in Sweden for an ATC should be quite good.
LFV is understaffed and has been for several years. It's gradually gotten worse because of controllers leaving the country due to the relatively low salary. You don't have to move far to almost double your income. Delays caused by staff shortage has been heavily debated in media the last months and they're even borrowing controllers from other countries at this point. Lack of ATC's seems to be a worldwide problem and Sweden is no exception.
