Langsdorf is the latest addition to coach Mike Riley's staff after he replaced Bo Pelini. Langsdorf previously coached for Riley at Oregon State from 2005-2013.
Langsdorf, 42, spent three years on the coaching staff of the New Orleans Saints under coach Jim Haslett from 2002-2004 as an offensive assistant before taking over as offensive coordinator and quarterbacks coach at Oregon State.
According to Ralph Vacchiano of the New York Daily News, the rest of offensive coordinator Ben McAdoo's staff is expected to return next season. In his first season under Langsdorf and McAdoo, quarterback Eli Manning completed 63.1 percent of his passes for 4,410 yards, 30 touchdowns and 14 interceptions.
The Giants finished No. 7 in passing yards and No. 9 in passing touchdowns this season, but missed the playoffs with a 6-10 record.
Head coach Tom Coughlin and general manager Jerry Reese were informed earlier this week that they will return next season.
