Campbell has been working at RB Leipzig for the past year-and-a-half but now makes the move back to the UK with Premier League giants Spurs.
He previously worked at Auchenhowie for over three years as Gers under-18s' Professional Phase Coach, responsible for professional development programme for young players.
He landed the job at the Light Blues after spells with Aberdeen and the Right to Dream Academy.
In February last year, Campbell took the decision to leave after the opportunity to work at RB Leipzig came up. In Germany, he has performed the role of Head of Player Development as he aided players with the transition of moving from youth level into first team football.
He will now work with the first team at Tottenham, who announced the full backroom staff of Frank this evening.
The Scot's new title is First Team Individual Development Coach.
As he left Rangers last year, Campbell signed out with an emotional message.

He wrote on social media: "Privileged to have spent 3.5 years at RFC Youth working with some brilliant people on & off the pitch.
"An incredible opportunity that I never took for granted, from watching academy lads play for Rangers & forging careers in the game to winning the U18 League & Scottish Youth Cup.
"Overwhelmed by the messages I’ve received from players, parents and staff which have all been greatly appreciated."
