In the U.S., a couple options:

Join the military - we have bases all over the world and chances are you might end up assigned to one.

Join a Federal Agency that does overseas work - State, Intelligence Community, etc.

Join a megacorp with a substantial overseas presence, apply only for jobs that are in countries you want to live in. They'll handle all the work visa nonsense.

The good news is that for most of these, there's lots of bonus pay/subsidized housing involved. Working overseas you can save unbelievable amounts of money.
