Head coach Robbie Neilson has made further additions to the football department with the appointment of an U20s Player Development Manager and an Academy Manager.
Former Dumbarton assistant Jack Ross takes on the U20s role, while Roger Arnott has been handed the responsibility of continuing the success of the much-vaunted Hearts Football Academy at Riccarton.
Jack started his professional playing career with Clyde in 1999, going on to feature for Hartlepool, Falkirk, St Mirren and Hamilton.
He was appointed assistant manager of Dumbarton in 2011 and was most recently No. 2 to Ian Murray at the Bet Butler Stadium.
Jack, who officially started in his new position today, said: "It's really exciting for me. I have been able to familiarise myself with some of the younger players in the recent friendlies. I can't wait to get started properly.
"What has happened at the club recently has probably meant these younger boys have had to deal with pressures they wouldn't normally have to. With the fresh start and new structure within the club, they'll have the best possible opportunity to get even better.
"I know the reputation the Academy has had for a number of years and I'm fortunate that I'll be able to work with the cream of that crop, those who have been deemed good enough to become full-time apprentice footballers.
"Hopefully I'll be able to give them the best opportunity to go on and become successful professionals."
Roger has been involved in professional youth football for the past 12 years and makes the step up after spending the last year helping develop some of the club's most promising youngsters as coach of the Academy's U12s while also being the Junior Academy Manager.
Highly-regarded, Roger has also worked as a regional coach with the Scottish FA and also spent time with sportscotland and Dunfermline Athletic.
"I am delighted to make the step up from Junior Academy Manager, where we have set up a really exciting programme to allow our young players to develop properly," he said.
"Being able to implement that through the whole Academy is an exciting challenge for me.
"We have some of the very best kids in the country and it's a great opportunity to work with them and develop them as they get older."
