(Not to scale.......obviously ;-) )

Hope this makes sense. I've never tried this before.

So the left hand end of the header joist could sit in a conventional
joist hanger nailed to the floor joist (or more likely a double joist I
would guess).

The right hand end would be held by a shoe like that I
described/pictured above. I expect there would also be a short floor
joist or two that hangs from your header joist, and help carry the floor
of the top landing area?

(Typically the stairs themselves are not usually counted as imposing
much load on a joist anyway. Half the load will be carried by the floor
below, and you don't tend to park heavy furniture permanently on stairs).
