Ssemanda made his senior debut for Uganda aged 19, at the 2007 WCL Division Three tournament. Uganda won that tournament to gain promotion to 2007 Division Two, where matches held list-A status. In the opening match of the tournament against the United Arab Emirates, Ssemanda scored 72 runs from 115 balls, his only list-A half-century. He later took 3/29 against Argentina, his best bowling figures. Ssemanda has since also represented Uganda in two first-class matches (in the 2009–10 Intercontinental Shield) and multiple twenty20 matches. In the East Africa Cup and East Africa Premier League, he played for the Rwenzori Warriors in both the 2011–12 and 2012 editions.
