McIntyre's Philymack company has been partnered with Roc Nation since 2015, but this move sees him taking on a new role at the entertainment firm JAY-Z founded a decade ago.
In this new position, McIntyre will oversee a client roster that includes Rihanna, J. Cole and DJ Khaled, along with a number of other artists, personalities and athletes. McIntyre's own clients with Philymack also include Iggy Azalea and The Band Perry and he is also an executive producer on ABC's American Idol.
Earlier this year, McIntyre was ranked No. 90 on Billboard's Power 100 list. He said at the time, "My focus is always ‘What do my artists' careers need next?'"
