This is what I found from PIAA:
Back Judge
Always positioned deeper than the deepest defensive back, normally taking an original position no closer than 15 yds deep and no more than 20 yards deep.
When the ball is on an inbounds line (hashmark), position yourself no wider than the opposite upright.
Know your eligible receiver responsibilities.
Echo referee's down signal verbally and with an overhead hand signal back to the Line Judge and the Linesman.
Responsible for the 25 second count. The PIAA mechanic is to raise and hold one arm straight overhead if the team has not snapped the ball at 20 seconds after the ready have elapsed; lower your arm at the snap or when the team has committed delay of the game.
If the field clock malfunctions, you will keep the game time and the referee will keep the 25 second count.
Responsible for counting defensive team. Confirm count with Line Judge using an extended fist; once in agreement, drop hand. Observe that replaced players leave the field immediately.
Key the tight end on the strong side. If a balanced formation, key the end to the Line Judge's side. On runs on either side of field, move to a position so that the runner is between you and the Linesman/Line Judge, observing blocks ahead of runner.
On out of bounds plays. especially in the team areas, move into the area of the dead ball and assist other officials in maintaining order.
With the Line Judge, echo the Referee's signal (winding the clock) when he starts the clock
The Back Judge has responsibility for the end line.
