Club career 
Early career 
Mariga started his playing career at Ulinzi Stars before moving first to Tusker FC and then to Pipeline FC while still at school. Mariga was a member of the Kamukunji High School 'Golden Boys', which also included Kenyan striker Dennis Oliech (Auxerre, France), who won two consecutive National Championships in 2002 & 2003.
The central midfielder went to Sweden in 2005 to play for third Division side Enköpings SK. After only one season at ESK, he signed for Helsingborgs IF before the 2006 season. His success at Helsingborgs was immediate. Following initial interest from Portsmouth manager Harry Redknapp, Mariga looked set to sign for the Premier League team, but work permit issues held up the deal which was supposed to have cost around €2.7million.
He moved to the Serie A club Parma initially on loan in August 2007. The Italian club had an option to buy him in the summer for a fee of 20 million Swedish kronor (around €2million). Mariga agreed to a four-year deal to keep him at Serie A side Parma for four years until the end of June 2012, after the club paid a transfer fee for Swedish Kronor 18 million (approx. 1.94 million euro). The deal, brokered by former Swede great Martin Dahlin, now an agent, falls short of the 20 Million Kronnor asking price initially set by Helsingborgs. 25% of the transfer fee will go to Enkopings SK, the club that first got Mariga to Sweden in 2005.
In January 2010 he was set to sign for English Premier League club Manchester City, but he failed to obtain a work permit. It was later stated by Kenya's Prime Minister Raila Odinga that 22-year-old Mariga had eventually obtained a UK work permit but only after the transfer window for the Premier League had closed. Had Mariga successfully signed for Manchester City, he would have been the first player from the East African country to sign for a club in the top English league.
Inter Milan 
On 1 February 2010, the last day of the transfer window, Mariga moved to Inter Milan in a co-ownership deal however he initially attempted a big-money move to Manchester City until a work permit was turned down by the Home Office. The transfer fee was €5 million in a cash plus player deal which Parma got half the registration rights of Jonathan Biabiany (€2.5 million) and the loan of Luis Antonio Jiménez. Following the move, Inter president Massimo Moratti hailed Mariga's move as the "best thing that could have happened" to the club in the January transfer window. He made his debut for Internazionale in the 1st leg of the 2009 Coppa Italia Semi Final against Fiorentina. Inter narrowly won the match 1–0. In March 2010 Mariga became the first Kenyan to play in the UEFA Champions League, when he entered the field as a late substitute against Chelsea.
Mariga thought he scored his first goal for Inter on 24 April 2010 against Atalanta when he netted Samuel Eto's back pass into the roof of the net. However his shot deflected off Sulley Muntari and the goal was credited instead to the Ghanaian. He also scored a thrashing header against Genoa for the Nerazzuri in a game that ended 3-2.
On 17 June 2010, Inter bought him outright and bought back Biabiany for a reported fee around €10 million. However on the official accounts shown half of Biabiany was valued €4.2 million, while Mariga's half was also €4.2 million. Thus, Parma booked an financial cost of €800,000 for the discount but on Inter side a financial income of €800,000, as Inter actually paid €9.2 million only instead of €10 million. Moreover Luis Antonio Jiménez originally included in the deal but collapsed after Inter lost its portion on 25 June. In January 2011 Inter gifted Parma half of the registration rights of Joel Obi for a peppercorn fee but never left Inter, and half of the registration rights of Nwankwo for a price nearly equal to half the price Inter bought him.
At the start of season Mariga was loaned out to La Liga club Real Sociedad. It made Inter had a non-EU transfer quota which used on winter signing Juan and Fredy Guarín (the other quota was obtained from Philippe Coutinho). As Mariga was unable to return to Inter, he was loaned back to Parma instead and he scored his only goal against Lazio. The next fixture he was injured against Novara, which resulted he will be out for the rest of the season. After that Inter Milan coach Andrea Stramaccioni wanted Jonathan and Mariga to be back from Parma.
