Basically a blue collar worker who makes white collar
money, is smarter than 99% of
people he works with, and they
will openly admit this to him.
You basically have to be fucking exceptional in: electrical, mechanical, hydraulics, pneumatics, water systems/plumbing, PLC troubleshooting, and diplomacy.
Also, you get to sleep in nice hotels, drive brand
new rental cars, and fly first class, all for completely free, and you are treated like a hero wherever you go, because you fix important shit. The ultimate bachelor life.
Operator says "Yo, the machine was fucked up for months, but we called the Field Service Engineer and he got it running like brand new in a

Manager says "I need to offer
that guy a job, he can replace my whole maintenance department!"
Field Service Engineer says "Fuck that, I make too much
money to give up nice hotels and fancy rental cars and first class air travel every couple of days. Let alone I can find a new tinder date every week!!!"
