Peter Parker should get some type of job in fashion. He designed and created his own stylish superhero costume by himself, so clearly he knows about fashion.
Working at a fashion company is also a good job that pays the bills, and he doesn’t have to worry about money while being Spider-Man.
It’s also not that time-consuming.
His job, canonically, has been freelance photographer. I think fashion probably beats that.
He’s a genius though… he could just be a freelance software developer that works remote.
