If you don't work IT, retail, or food service what do you do for work?
Sometimes on Lemmy these seem like the only jobs that actually exist, but I'm sure there's a lot of people here with different and unusual lines of work.
I helped design large-ish electrical grids. 30-100k cables
Without the actual calculation bits, unfortunately.
Not very interesting. Bad software. Management didn't really care about the problem. I was there so the problem was "managed" from their point of view.
The boring part. Making sure that there are holes in the walls for sockets, enough capacity in the cable trays. Planning the routing, but I didn't have access to algorithm of the software.
Collecting the ever changing inputs from people who want devices with cables in rooms and spaces. :)
