Narrative:
While departing las on the oasis 5 SID gfs transition we were cleared to climb to FL140 when reporting local at FL140 the controller told us to expect higher in 5 min. We then heard controller tell air carrier Y flight to descend to FL150. The controller then cleared us to climb to FL230 expedite through FL160. As we started to climb the controller called traffic at 2 O'clock. We looked and saw an medium large transport coming straight at us in what looked like level flight at about FL150. I started an immediate left descending turn and at about the same time saw the other aircraft start what looked like a climbing left turn. He passed to the right and behind us.
