A big problem for a lot of people as it is not easy to get a job in Spain when you are living in Scotland and it is a bit of a risk 'just going over there'
Good skilled people generally can find work anywhere
I can give you all the help you need to re locate settle in and the technical aspects of working in Spain but on the jobs front you just have to go over and start looking
There are web sites you can look at on google so you may find some info
Why not spend a couple of weeks over there just looking and going direct [cold call]to potential employers and see what turns up
