Kamara started his career with Football Club Kallon and joined on 29 July 2011 on loan to Division 1 Norra side Bodens BK. He scored five goals in his five months on loan in 10 games for Boden. The striker signed a contract on 5 October 2011 with AIK. During the first half of the 2012 season, he made 11 appearances for AIK. After the summer he was loaned out to Örebro Saskatchewan, where he made four goal in eight appearances. On 24 January 2013 it was announced that he again was loaned to Örebro Saskatchewan, for the rest of 2013.
After the season Örebro Saskatchewan decided to buy him from AIK, where he never had made any impact.
After getting injured early in the 2014 season, Kamara scored his first goal on 9 August against Mjällby AIF. He then proceeded to score, ending the season with 14 goals in the 12 last games despite often being substituted off in the second half (he played 90 minutes in 7 out of 19 games). He averaged one goal every 65 minutes in the last 12 games of the season, finishing with a hat trick in 7 minutes against BK Häcken.
On 2 June 2012 he made his senior international debut for Sierra Leone in a 2014 Fédération internationale de football association World Cup qualification game against Cape Verde.
