In my experience, at least, the vast majority of software development jobs are developing this kind of 'enterprise' infrastructure. The technical details are usually straightforward and the complexity is in meeting the needs of the users and the business, and the amount of processing required is trivial on modern computers to the point where implementation performance almost never matters. Jobs where you need to do anything tricky or performance-sensitive, where it's worth knowing fancy algorithms and low level implementation details, are few and far between.
