Aside from the implication of rank suggested by the use of "Senior" in their titles there is no functional administrative difference between the two. A 1978 statute has been seen by some (Kushner's lawyers among them, not surprisingly) as clearly superseding the 1967 law provoked by Bobby Kennedy's appointment, but even that may not have had any relevance.
some discussion of the question.
The WaPo article they cite is worth a peek, too.
So, no technical difference between Kushner's job and Ivanka's, really. Which one Trump actually thinks of as the "senior" of the two is anybody's guess. In a toe-to-toe disagreement between them I'd put my money on Trump listening to Ivanka first ... if he was to listen to either of them, that is.
