Joe is a Glader and Runner whose name was seen engraved on the wall of the Glade in the Maze Runner film. His name was not crossed out at the time, therefore he was alive when Thomas arrived. He is rarely ever seen. Joe is confirmed to have died during the Griever attack. In Maze Runner: The Death Cure, Joe's name is seen engraved on the memorial rock. The name Joe may be a reference to the executive producer of the movie, Joe Hartwick Jr.
