Briscoe, 30, hung up his boots at the end of the 2013 season, and returns to Rovers, for who he played 100 games between 2008 and 2011.
His new role will see him work closely with Head of Youth Pete Grayburn to develop and improve the club’s youth set-up, and take up the role of Under 19s assistant coach.
Briscoe said: “I was thrilled to be offered this role and I’m really looking forward to getting stuck into the next period of my career. Rugby League is in my blood and it’s great that I will have the chance to stay in the game I love. I’m passionate about helping young players progress and hopefully I will be able to use my experience to help develop the young lads coming through at Hull KR.
“The club is quite a different place to when I left, with the new North Stand open and Craig moulding his own squad it’s an exciting time to be getting involved.”
Briscoe played for city rivals Hull and Wigan before first moving to Craven Park, and spent the last two seasons of his career at Widnes.
