Ah yes! That is a great trick that kept me going doing software dev professionally.
Instead of trying to get the system I was working with to interact correctly with some shit enterprise system, I would find common protocols (or related protocols) and implement that well. Then I would discover more specifically where the shit enterprise system was behaving badly, and point to something politically neutral (like an IETF RFC) to help get us out of a rut.
It made debugging so much easier. Those specifications and open-source implementations have had much more engineering talent put in them than what I was usually dealing with.
Unfortunately for those who have those values, not all paid positions involve acting on those values.
Random brain dump incoming...
Most businesses pay money to solve problems so they can make more money. You can solve their problems - but not in the way that you may be thinking.
This is a generalisation that is not strictly true, but I say it to illustrate a different way of thinking: Businesses do not undertake penetration testing because they want more secure software. They do pentesting so they can stay in business in the face of compliance and bad actors.
To find a job, you want to start learning what people pay for. People pay contractors to come in and fix things, then leave again (politically easier, sometimes cheaper). People pay sotfware developers to develop features (to sell more stuff).
Start looking up job titles and see which ones interest you (DevOps, frontend dev, backend dev, embedded...). Don't get too stuck on the titles themselves. It's just to narrow down what kinds of business problems you find interesting.
Other random questions:
Once you're deep in the belly of the beast, you'll find ways to exercise those values. It's hard to know in advance what this will look like.
