The Dodgers announced Tuesday that Maddux and Ibanez will work under Andrew Friedman, who is president of baseball operations.
Maddux, 49, has front-office experience with the Chicago Cubs in 2010 as assistant to general manger Jim Hendry and with the Texas Rangers from 2012 to 2015 as a special assistant to general manager Jon Daniels. He also served as pitching coach for Team USA in the 2013 World Baseball Classic.
Maddux was elected to the Baseball Hall of Fame in 2014 in his first year on the ballot after a 23-year career with the Chicago Cubs, Atlanta Braves, Dodgers and San Diego Padres. He finished with a 355-227 career record and a 3.16 ERA.
Ibanez, 43, spent the 2015 season working as a television analyst for Fox Sports after his 19-year career in the major leagues with the Seattle Mariners, Kansas City Royals, Philadelphia Phillies, New York Yankees and Los Angeles Angels ended in 2014. The job with the Dodgers will be his first in the front office.
As a player, Ibanez had a .272 career batting average with 305 home runs and 1,207 RBIs.
