Paul Wellens has taken up the role of Player Performance Coach at St Helens.
Wellens will work with the under-19s, scholars and reserve teams, as well as shadowing the first-team coaches.
The 35 year-old, who announced his retirement from playing in June as a result of a hip injury, will combine the new role with his position as England’s assistant coach.
The former Great Britain international made 499 appearances for Saints, the club where he spent his entire professional career.
Wellens said via the club’s website: “I’m really pleased to remain at the club and help nurture the future talent coming through the club. I’m here to mentor and develop the youngsters to not only become better players but responsible and professional people too.
“I’m looking forward to working with Derek Traynor, Ian Talbot and all the coaching staff.”
Saints Chief Executive Mike Rush added: “Clearly, having someone with the knowledge and experience of Paul Wellens at the club is a massive boost. He is one of our most decorated players and instantly commands respect within the club and amongst the players.
“His experience will be crucial to bringing through the next batch of talent from our Academy system that has been rated Outstanding by the RFL.
“He has already started work and I know all those in our junior set up, appreciate his work ethic and knowledge.”
