Nangula is a Chartered Accountants by Profession and has served as an auditor and business consultant over 24 years at PwC Namibia until 31 December 2020 at the end of her 10-year service as the Firm's Country Senior Partner.
Over the years Nangula has grown a burden concerning the triple challenges of unemployment, inequality and poverty that are facing Namibia. It is this burden that led her to pursue further studies (first the Master in Business Leadership and now Doctor in Business Leadership) with focus on the collaborative role required between the public and private sectors to drive inclusive economic growth and find common solutions to these challenges. It is also this burden that led to her resignation as the CEO of PwC Namibia in December 2020 and acceptance of the President’s appointment to the role of first CEO and Chairperson of NIPDB.
