Pulleyblank obtained his Ph.D. from the University of Waterloo in 1973; his thesis, supervised by Jack Edmonds, concerned perfect matching theory from the point of view of polyhedral combinatorics. He worked at IBM beginning in the late 1960s and then returned to academia in 1974, as a professor at the University of Calgary, before moving back to Waterloo in 1982. At Waterloo, he held the CP/NSERC Chair of Optimization and Computer Applications. In 1990 he began a second stint at IBM, where his work included leading the Blue Gene project. He was promoted to vice president in 2004, and retired from IBM in 2010, at which time he joined the West Point faculty.
