Are you sure you are senior? Because in my 22 years of experience in 3 countries and host of employers (banking, telco, insurance, military, municipality, energy distribution, retail etc) it was always management setting the tone and only fools ignore the hand feeding you and go against it due to some 'higher principles'.

No we don't need to have documentation and keep updating it what you can't read code? No we don't need to rewrite system that was patched ad absurdum so codebase became fragile and its hard to navigate layers of abstractions. We need to deliver this project yesterday at all costs since somebody up there slept on requirements for 6 months and didn't do their basic job, and we will never pick up half-assed pieces we were forced to deliver. No we don't need to update those 12 years old libraries, too much work and testing. I could go on and on.

It seems like you consider engineering to be delivery of perfect things, or utter failure. Thats not how things are anywhere, sw dev is more unstructured but you also don't have 5 million ways to build a good wall using every possible substance in the universe, do you.
