"We are very excited to have Mike fill such an important role with us," Oilers GM Steve Tambellini said in a statement. "We know his experience of 1,000-plus NHL games will benefit our younger players and the development of their careers."
Sillinger, a native of Regina, Saskatchewan, will work closely with all Oilers draft picks in the junior, college and European ranks. He will also work with Edmonton's prospects in the AHL and ECHL.
Sillinger announced his retirement earlier this month after a career that saw him play with an NHL-record 12 teams, including the last three years with the New York Islanders. He underwent hip operations in each of the past two years and played only seven games in 2008-09, scoring 2 goals.
He finished his NHL career with 240 goals and 308 assists for 548 points in 1,049 games.
Originally drafted No. 11 in 1990 by the Detroit Red Wings, Sillinger began his NHL career in Detroit before playing for the Mighty Ducks of Anaheim, Vancouver Canucks, Philadelphia Flyers, Tampa Bay Lightning, Florida Panthers, Ottawa Senators, Columbus Blue Jackets, Phoenix Coyotes, St. Louis Blues, Nashville Predators and the Islanders.
Sillinger also represented Team Canada on two occasions, winning a gold medal at the 1991 World Junior Championship and leading his country as their captain at the 2000 World Championship.
