I won't name the industry out of privacy paranoia, but I do large scale IT technical architecture and lots and lots of classic system engineering (requirements gathering, writing specifications, implementing those, writing manual pages for the software I develop). The reason I'm able to do that is due to massive off-shoring at the client where I consult: I am one of the handful of people left in "a high cost location" who can debug, link, compile and package software correctly, thereby making large and complex software easy to install and JustWork™️. Management is for the most part unaware of all of my software running underneath until some major application goes live and then I give them a presentation on what is ticking underneath.
This comes from my days of assembler coding of intros and cracking software on the Commodore64 and the Amiga: one learns the value of writing small, fast code very quickly and that programming and code design style stays with one for the rest of one's life.
With its vast memory, processing power and built-in tools like AWK, UNIX®️ makes that style of programming small, fast software even easier. I spent decades studying what all UNIX®️ and its tools can do and have to offer though.
