Josh, 19, emerged from Maidstone Utd’s academy and was invited to trial at Brighton & Hove Albion before going on to play for Sevenoaks Town last season.
Midfielder James Miles, who came through Ebbsfleet Utd’s academy, returns after making three appearances last season and going out on loan to Rusthall in the Southern Counties East League Premier Division.
Ryan Huckle, Mitch Chapman, Jamie Maxted, Donvieve Jones, Michael Freiter and Simon Overland are among those who have already been unveiled for the coming campaign.
Joint manager Phil Miles said: “Josh played under me at Ebbsfleet as a youth player and is a young talent – a skilful centre-half who can get the ball down and play.
“I’m delighted that James is back with us too. The squad is slowly coming together, but we won’t sign people for the sake if it.
“They have to have the right attitude and fit with the way we want to train and play, and [fit in with] the budget we have.
"It's a bit of a waiting game for some players, but we have to be patient to make sure we get it right.”
The first chance to see Town’s new players will be the friendly against Gillingham at Salters Lane Stadium on July 6, 2pm kick-off.
