I am in the same boat. It also feels like the more time I spend at one company in one role the more I gain crazy amounts of context over every aspect of our software, so the less effort it takes to do the same amount of work. I can do many tasks in < 30m that would take anyone else an entire day.

The old guys who have total ownership over some esoteric but irreplaceable part of the code really have it made. Especially if they are working remotely. At that point you almost are like a piece of B2B SaaS software. As long as you do your task tolerably well no one wants to go through the hassle of replacing you.
