I've used Reed years and years ago but not sure how good they will be out there! + just a quick look on that page only 13 match IT when filtered but look worth looking into!
Good luck with your search.
Indeed.es Tecnoempleo.com Monster.com or Monster.es (full of jobs, but a faff to use-grr) Inforjobs.net Talent Search- Spanish agency that are worth getting in touch with. This link is for the EU job portal, again, a faff to use, but worth having a deek. I`ve had some stuff via this source. You`ll have to convert your CV to their format, but it`s quite straightforward. When you register as a jobseeker, you will be able to download the template, called Europass, to mangle your CV.
Hopefully that will give you an idea of what is going on over here.
