You can definitely find tech jobs in Portugal and Spain, mostly in Lisbon and Barcelona. They will not pay the same as in Germany, the Netherlands, UK or here in Sweden but you can live very comfortably with a tech salary there, so there's middle ground.
Italy unfortunately doesn't really have a well developed tech industry as far as I know.
Why not? Not many Earth shattering startups but being one of the largest EU economies means that Italy has many IT jobs. I spent the first half of my career in a 1000 people consulting company and a 3000 people mobile phone operator. Then I went freelancing, mostly web, and I pay my bills. There are many SME tech companies, selling their own products and services or consulting.
There is quite a difference between the South and the North, two very different economies. If you ever want to try to work Italy go to the North. Probably Milan is the safest starting point.
That said, I'm sure that the UK, Germany and France are better off than Italy, even the North of it.
