Steve Cooper will stay at the club.
The manager's position was in question after his side fell to the bottom of the league.
The decision was made that he should be given more time in recognition of his achievement.
Filippo is the club's new sporting director.
The club's current difficulties are seen as an attempt to guide the club through their current problems and give them the structures needed to progress as a premier league club.
After his first season in charge, Cooper took them back to the top flight for the first time in 19 years.
He spent over one hundred million dollars in the summer transfer window.
Forest have only won once in the league this season and have lost their fifth game in a row.
After working as a chief scout for nine years, he moved into the technical director position.
His experience will help ensure Forest have the best chance of avoiding a return to the Championship.
