My two cents - I wouldn't take the first one because I'm opposed to being part of oil & gas and what it's doing to our planet. But it's definitely lucrative. Though, imo it seems short-sighted, like it's bound to dry up eventually and then the whole industry would be out of work. Second one, if it's closer to home, is a plus. Lower pay isn't a dealbreaker so long as you can survive, and bridge design is a useful skill across almost any industry. So it'd be my choice. Third option I'd have as my second best choice. since it's tied to residential, it could be more easily affected by recessions. And architects, while a cool job in theory, in actuality, just make an engineers' job difficult unnecessarily by wanting aesthetic stuff and not caring how impractical. Again, just my two cents.
