Offshore seismic survey. The positions vary in title, but technician, observer, seabed logger, etc are, quite honestly, easy as fuck. If you're able to display reasonably good troubleshooting skills and adaptability to a "different" kind of job, you're golden. Pays quite well too. Your background certainly plays a role, but it's more about being the right kind of well-rounded personality.

Pros: Computers, heavy machinery, robotics, nice people, loads of travel, nice ships (most of them, at least), five weeks at home to do whatever you want, well paid.

Cons: Five weeks offshore gets tiring, you sometimes find yourself in the shittiest shitholes in the world, the work can be really repetitive and boring, and if you're unlucky you will find yourself on a ship with shitty food.

Source: I used to be one. Now I hold a more specialized supporting role instead. Been in the industry since 2008, and before that I had no fucking clue what I wanted to do with my life. It didn't take me long after to figure out "what I want to be when I grow up". I'm now 41, not quite a grownup, but I definitely am happy with my career.
