I moved from Spain to the Netherlands with almost 0 change. Working on IT helps, of course, but it's still pretty easy. Jump on a plane, register on the city council, there you go.
I moved from the Netherlands to Spain (the south) with 0 change. Working in IT helps; I work remotely and do exactly the same as I did when I lived in the Netherlands. If you want to work you can, anywhere.
We actually were looking for IT people in Malaga, but it seems that people don't really want to work. I know enough companies from 'the north' looking for people in the south; people are just not applying and if they do they mostly ask for weird conditions... I know dev jobs for at least 100 people at different companies which cannot be filled in Malaga.
