With the Reds clearly set to name a head coach now rather than a traditional manager, Pereira will take responsibility for transfers.
His background, mainly with Sporting Braga of Portugal and then with Fiorentina in Italy, is in scouting and development.
Further details about the appointment are available on the official NFFC website.
Attention now turns to who will take charge of the first-team in 2016/17 with Ryan Giggs the latest name in the frame.
