Flight instructor/local commercial pilot. The pay is garbage compared to software development but if you're an independent CFI there is as much time freedom as there is being a remote dev, and the pay is still good enough to cover all the necessities.
I used to flight instruct in my twenties. Couldn't make a decent living in aviation and had to switch to something else. Software development has its benefits, but having an office in the cloud beats everything else.
CFI is my retirement job. Already have my private, so I'm working towards my commercial now. Once I'm starting to feel like the old man of the team, it'll be time to move to a beautiful part of the country with lower living expenses and let students try to kill me all day.
Bonus: if I work in the tech industry long enough, I can afford to pick up a few 150s and start a school.
