Alitalia has not hired for some time, but Alitalia Express has.
To work in an Italian airline you will need the ENAC CC Certificate (Certificazione) which is quite complicated to obtain since you have to be hired by an airline to obtain it (unlike in France where you can get it by yourself), and struggle for months of underpaid work and subtle blackmail of being fired if you don't agree on working extra hours and canceled days off. Sad but true.
I suggest that you consider other airlines, since it could take some time to get a reply from AZ. This provided you have the Italian Certificazione, of course. Otherwise you migh want to look at some foreign LCC based in Italy which I'm told do not require it.
Good luck.
