Google pays 120k+ for junior developers in Switzerland.
Switzerland is not in the EU as OP asked, also you spend a large chunk of the gains over Germany on higher living cost (rent, but also basic stuff like cheeseburgers is up to 3x the price of Germany). Oh and they have both a strict immigration regime as well as a huge right-wing problem, which might be another factor against moving to Switzerland for work.
OP asked about EU/EEA. Switzerland is not in the EU but it could just as well be in EEA. Only reason it's not is because it has to be neutral on paper for historical reasons. De facto Switzerland is clearly EEA-like.
