Sources: Seahawks hire Gray
Seattle has also decided to retain Gus Bradley as its defensive coordinator.
New Seahawks head coach Pete Carroll will have a heavy influence over the defense with his background, but Bradley and Gray will work closely together to try to make sure the Seahawks improve their defense next season.
The Seahawks had the league's 24th-ranked defense in 2009, allowing 356.4 yards per game, and tied for 25th with the Miami Dolphins in points allowed, with 24.4 points per game.
Gray, an assistant on Jim Zorn's staff in Washington, had interviewed for the Redskins' head coaching job.
