Remove section of load bearing wall

Hi, I want to remove two studs on a load bearing (I assume, because its the only wall at a half way point of a house) wall to create an opening between my kitchen and living room area. This is on the upper floor so there is only have a roof above. The roof is pitched, I think with the peak more or less over the wall I want to remove. Is this something I should consult a structural engineer about?What I actually want to do is create a window or an opening between the two areas, not necessarily a door and I'm wondering if anyone has any suggestions or pointers.

Thanks a lot.
