My understanding is that as Spain is a member of the EEC there would be no bars to you either moving out to Spain to live or seeking employment there. However, unless you have a particular skill which is needed and a good working knowledge of the Spanish language you may be under-estimating your chances of making a successful transition. I guess bar work in a tourist area is always an option, but if you really want to live and work in a different country, if you're not prepared to integrate and become a virtual Spanish citizen there really isn't any point in making the move.
