I'd say no matter what kind of job you get, you can put 10% of your time into similar problems. Even simple CRUD apps can have interesting problems like this. In my experience every project has instances of engineers shooting themselves in the foot, or unforeseen problems cropping up. If you have a bit of self-motivation you can dig into them and learn a lot and improve things. I do this and find it very satisfying.
