The former Watford defender was drafted in to provide cover for his former Hornets team-mate while he was in hospital, and was part of the Pompey staff until Jackett was sacked as manager on March 14.
Before his short stint at Fratton Park, Gibbs was the assistant coach to Paul Clement at Cercle Brugge in the Belgian Pro League.
He also had previous experience as a coach and assistant manager at Reading, Leeds, Millwall and Swansea City.
After previously coaching Spurs’ under-19s, Gibbs returns to north London and links up with Chris Powell, Michel Vorm and Ledley King in Mason’s backroom team.
Former Spurs midfielder Mason, 29, has been named as interim head coach of the Premier League side until the end of the season, following Monday’s sacking of Jose Mourinho.
He has been involved in the club’s youth setup since 2019.
Mason’s playing career was cut short in 2017 after sustaining a horrific head injury.
