Are you allowed to work in Italy? Work Permits explained.

EU/EFTA Nationals do not require a visa or work permit to work in Italy.
Non-EU citizens require a work permit or a working holiday visa. Work permits must be applied for by the employer via the Italian Consulate and it is essential to have one before you start work.

As is common across Europe, occupations that are in high demand of employees tend to have more chance of being granted permits, and the employer needs to prove that they cannot fill the role with Italian or EU candidates.

The Italian work permit is administered regionally, so the rules differ significantly depending on the exact destination within Italy – again the advice is get the job offer and the employer should sort the work permit out for you.
