For example: ...until/before I have been working here...
WRONG, why?
A complete sentence would be:
Before I have been working for McDonald's, I had been working for Chipotle.
The subordinate clause here logically means that I am presently working for McDonalds's. (The action is continuous, started from some point in the past.)
Were it not present perfect, the action would be non continuous and would sound vague.
