"Billy has only been retired as a player for one year, so he brings a new and very contemporary perspective to the position," Penguins General Manager Ray Shero said in a release. "He is going to be a big asset to our young prospects throughout the organization, and to our staff."
Guerin, 40, will work with Penguins prospects at the minor league, junior and college levels.
Guerin helped the Penguins win the Stanley Cup in 2009 and New Jersey in 1995. He played 1,263 NHL games for eight teams, producing 429 goals and 427 assists. Guerin also played on the U.S. team in the Olympics in 1998, 2002 and 2006.
