Every company I’ve seen that needed people dedicated just to fix bugs was in a downward spiral with maintenance mode software. Those organizations outside really slow moving but well financed bureaucracies are disappearing rapidly as investors pull money by divesting or selling to larger companies that wind up casting off the unprofitable / non-growing lines of businesses they acquired.

It’s pretty evil IMO to hire people as FTEs into such organizations when you are probably better off with consultants that are at least used to short term gigs.
