Born on December 30, 1976, in Częstochowa, Poland, Magiera was 1.85 meters tall and played as a defensive midfielder, but could also play as a center-back.

Magiera joined Raków Częstochowa's youth academy at a young age and completed his Raków Częstochowa first-team debut in March 1995.

In January 1997, Magiera moved to Legia Warsaw.

During his nine-year spell at Legia Warsaw, Magiera won one Polish Ekstraklasa title, one Polish Cup, one Polish Super Cup, and one Polish League Cup with the club.

During this spell, he also played on-loan for Widzew Łódź and returned to Raków Częstochowa on-loan.

In September of the same year, Magiera returned to Legia Warsaw as head coach. During his tenure, he led the club to one Polish Ekstraklasa title, becoming one of the few men in football history to win a league title with the same club as both a player and a head coach.
