The move Sunday reunites Monken with Bucs coach Dirk Koetter. The two also worked together in Jacksonville, where Koetter was the Jaguars offensive coordinator and Monken coached wide receivers for four seasons for 2007-2010.
"I am very excited to add a coach with the type of experience and tenacity that Todd brings," Koetter said in a statement released by the team on Sunday. "I have always been impressed with his approach to the game as well as his ability to teach concepts and get the best out of his players."
Monken, 49, will take over the coordinator position previously filled by Koetter, who was promoted to head coach last week after Lovie Smith was fired by the Buccaneers after going 6-10 this season.
Southern Miss slowly improved during Monken's three years in Hattiesburg. The Golden Eagles had a 9-5 record last fall after a 3-9 season in 2014 and an 1-11 mark in 2013. They also played in a bowl game for the first time since 2011, losing 44-31 to Washington in the Zaxby's Heart of Dallas Bowl. It was quite a ride for a program that had a 4-32 record over the previous three seasons, including a winless 2012.
Southern Miss ranked in the top 20 in scoring, passing and total offense last season. His college coaching resume also includes a stint as offensive coordinator and quarterbacks coach at Oklahoma State, where he tutored Brandon Weeden.
"During his more than 25-year coaching career, he has made a name for himself as a very successful offensive coordinator and head coach on the collegiate level," Koetter said.
Monken had coached Jacksonville's receivers for four seasons prior to taking the Southern Miss job, helping develop starters Mike Sims-Walker and Mike Thomas. Monken previously worked on the college level at LSU, Oklahoma State and Eastern Michigan.
The Buccaneers ranked in the top 10 in total offense, finishing No. 5 offensively. But they struggled to get the ball into the end zone, ranking 20th in points.
