Former players Jonny Bell and Niall Malone have been appointed to Ulster's academy as elite player development officers.
The former Ireland pair arrive along with Arran Peck - who has been named fitness and conditioning coach.
Bell made 81 appearances for Ulster and won 36 international caps while Malone's career included six seasons with English side Liecester Tigers.
"I am really excited about this challenge and looking forward to carrying on the good work of Neil Doak," said Bell.
"The Ulster Rugby Academy system has a great success record - players like Andrew Trimble, Stephen Ferris, Ryan Caldwell, Paul Marshall and young Niall O'Connor have all benefited greatly from the academy expertise and support.
"I hope to be able to add my own experience and give those young aspiring players an insight into the reality of being a pro player."
