Uber SVP of Global Operations will be leaving that full-time senior leadership role in the middle of September to “focus” on his role as a director of Uber’s board.

Graves, who acted as Uber’s CEO from early 2010 until founder Travis Kalanick took over the position at the end of that year, had been seen as a close associate of Kalanick’s over the course of his long tenure at the ride-hailing company.
