Maazou began his senior career as a player with Niger's Army club, ASFAN of Niamey. In 2005–2006 Maazou scored 17 goals. In the 2006–2007 season with ASFAN, he scored 20 goals in 34 matches. In January 2008, Belgian side Sporting Lokeren signed him. He scored six goals in his first nine matches. On 3 January 2009, Maâzou signed a contract with CSKA Moscow. The club paid Sporting Lokeren €4.8m for Maazou. He was immediately loaned back to Lokeren until 1 July 2009. After CSKA qualified for the round of 16 of the UEFA Cup 2008–09, he was called back from the loan and on 12 March 2009 was registered as a CSKA player. In January 2010 Maâzou left Russia, signing a six-month loan deal, with an option for a permanent move when his loan spell ends, with AS Monaco. The following season Maâzou joined FC Girondins de Bordeaux on a one-year loan, again with an option to purchase. At the end of January 2011 Maâzou returned to AS Monaco on another six-month, but after only one game injured his knee in training and would require surgery.
In February 2012, Maâzou signed for Le Mans on a six-month loan deal, before moving to Tunisian side Étoile du Sahel on a 3-year contract during the summer of 2012. After terminating his contract with Tunisian side Étoile du Sahel, Maâzou signed for Vitória Guimarães in Portugal in July 2013.
He switched to another Portuguese club, Marítimo on August 2014. On 28 January 2015, at that point the Portuguese top flight's second top goalscorer of the season with nine goals, Maâzou transferred to Chinese Super League side Changchun Yatai.
In April 2015, Maâzou announced his retirement from the Niger national football team at the age of 26, after having earned 30 caps and scored seven international goals. He credited the dismissal of manager Gernot Rohr in the previous October as a reason for his decision. However, in October returned to the national team, scoring two goals against Somalia national football team in the campaign for 2018 World Cup.
