HAWTHORN great Jarryd Roughead has made his choice on his post-playing destination, agreeing to join St Kilda's football department.

Roughead played his 283rd and final match a fortnight ago against Gold Coast, which tried unsuccessfully to lure the four-time premiership forward in a similar off-field role.

The 32-year-old has committed to the Saints for the next three years, starting in November, after being spotted touring their Moorabbin facilities in early August. 

He will work in list management, the club's leadership and mentoring program, and will perform a match-day role, as well as helping develop some of St Kilda's young key-position players.

"I'm looking forward to working across the football program and with a really talented young group of players, and contributing where I can to their development," Roughead said.

"St Kilda presented an appealing role and have a very clear direction in where they want to take the club over the next few years.

"I'm looking forward to getting started and thank them for the opportunity."

Saints football boss Simon Lethlean was thrilled to win the race for Roughead.

"He will add huge value to a number of areas in our program," Lethlean said.

"(He will support) James Gallagher in list management and recruiting, while also playing a key role in developing our young leaders to help drive the standards that are required to win premierships.

"As one of the game's best key forwards over the past 15 years, we will also utilise his knowledge to support our coaching group, where he will work with our talented young key-position players to develop their craft."
