Does cutting into a joist to close to the top ruin it?

A "carpenter" did this to a big double joist in my house (top floor), I was under the impression that one does not cut a hole this close to the edge of a joist, especially not one this big! Should I be worried about this joist and how would I go about repairing it?[enter image description here]

The cut is about 1.2 meters from the wall 1
