Getting a job in Europe with an American degree?

I'm an american Mechanical Engineering student at the University of Florida. I also have european citizenship which simplifies a lot.

I'd like to eventually move to Europe after I graduate, but would like to know more about the process of getting a job in Europe in engineering and how it would work with my degree since in Europe engineers generally graduate with a 5 year masters and I will graduate with a 4 year bachelor's degree.

How are American degrees viewed in Europe? Is a Master's necessary or would a degree transfer grant me an equivalent 5 year degree in Europe? And what is the process of job searching like with regards to internships and recruiting?

I would preferably like to live in Northern Italy (Turin) but am open to France, Germany, Netherlands etc. where engineering is also very present.

What is the best course of action?
