You'd be surprised how many such jobs are there. Mostly not listed though. If my experience is any guide, one generally starts as a temp / consultant and you slowly expand the role from there. There's generally a point some years later where you're almost "too big to fail". Too many small odd jobs that are needed maybe once a year, but when they happen, they are pretty important.

Important to note that this too big to fail point occurs very quickly in some cases. Non-IT companies are generally very risk/change averse in regards to their IT infrastucture (and for very good reason, see e.g. [1] and [2]). So if you are capable enough to learn their legacy codebase you will be very quickly the only person worldwide capable of maintaining it.
