Prior to her senior political career, Namayanja worked as an academic registrar for
Light Bureau of Accountancy in 1998. Between 1999 and 2001, she worked as a political officer at
State House Kampala. She started her political career as a student and youth leader at
Makerere University in 1995. She was a founder member of the Uganda Young Democrats (UYD), the youth wing of Uganda's Democratic Party (DP). According to her, she drew her inspiration from the then young people in politics like the late
Nobel Mayombo and further from the powerful women in politics like the former vice president of Uganda,
Specioza Naigaga Wandira Kazibwe,
Winnie Byanyima,
Janat Mukwaya and
Cecilia Ogwal. The desire to make a contribution to rebuilding
Luwero Triangle, her homeland and the theatre of
Yoweri Museveni's liberation war made her aim for more influential political positions. In 2001 at the age of 25, she was elected as
Member of Parliament (MP) representing the youth for Uganda's Central Region, which includes
Luwero Triangle, for a five-year term. In 2006, having crossed to the NRM after the introduction of Multi-Party Politics and the creation of
Nakaseke District the previous year, Namayanja stood unopposed for the position of Woman MP for Nakaseke District and was reelected in 2011 for a five-year term. In 2011, she was appointed for her first ministerial position as
Minister of State for
Luwero Triangle in the
Office of the Prime Minister (OPM). She held that portfolio until she was appointed
Minister of information and National Guidance on 23 May 2013, a position she held until 1 May 2015, when she was dropped from the Cabinet in consideration of the fact that she had been appointed
National Treasurer of the
National Resistance Movement in January 2015. Namayanja did not contest the
2016 general election. Namayanja is the current Deputy Secretary General of the National Resistance Movement as appointed by the Chairman in 2021. ==Personal life==
