Vaitai was drafted in the fifth round, 164th overall, by the Philadelphia Eagles.  It was announced on May 6, 2016, that he had signed his rookie contract with the Eagles.  The contract was reportedly for four years and $ 2,565,124.  After starting right tackle Lane Johnson was suspended for ten games, Vaitai made his first start in Week 5. He held the starting job through Week 11 before suffering an MCL sprain in that game, keeping him out of the starting lineup the rest of the season. 
In the 2017 season, Vaitai filled in for right-tackle Lane Johnson against the Carolina Panthers due to injury. He would then fill in for injured left-tackle Jason Peters in Week 7 against the Washington Redskins and for the rest of the 2017 season.
