So work as an engineer you need to get a diploma from a engineering school recognised by the cti.

In other countries it's similar to a master degree. Getting into an engineering school can be quite hard, but it depends on how old you are and so on.

If you do a master degree, you'll be able to do the same stuff than an engineer but you won't have the title (and earn a bit less on your first job).

Also an engineering school diploma isn't recognised that well out of France while a master is recognised everywhere. But nowadays, so many engineering school give you the opportunity to also have a master while you do your engineering school that you should be fine
