Mission

Design and maintain MTN’s Network Security architecture to protect networks, systems and applications. This involves defining, planning, architecting and coordinating the implementation and maintenance of information security necessary to support the OPCO’s IT, Digital and Telecommunications network. This also includes optimisation and standardisation of information security across the enterprise, which includes the product and infrastructure lifecycle management and roadmaps across all IT infrastructure, mobile network and application platforms, including new builds for short-term renewals, medium and long term tactical and strategic plans.

 

Context 

 

Security is entering a new phase where the architecture and systems between IT and the Mobile Network are now using shared platforms or infrastructures. There is an increased focus in the security of these networks and across all areas of the business. The introduction of cloud has blurred the lines between a traditional IT security professional and a Mobile Network Security function. The candidate is further responsible for vetting and advising all OPCO’s in the MTN portfolio on Core network, Digital and IT security related projects.  The incumbent must therefore ensure the successful delivery in context of:

  • An expertise-based multicultural federated organisation 
  • A dynamic and evolving field of information security 
  • Revolutionary workforce practices which are bringing together global labour markets
  • Evolving industry sector constantly presenting new challenges, opportunities and threats to the core businesses
  • Dynamic legal and regulatory environment
  • Agile ways of working
  • Hybrid networks (cloud and on-premises)

 

 

Values

We at MTN are a purpose and value-led organization. At MTN, we believe that understanding our people’s needs and aspirations is key to creating experiences that delight you at work, everyday. We are committed to fostering an environment where every member of our Y’ello Family is heard, understood and empowered to live an inspired life.

 

Our values keep us grounded and moving in the right direction. Most importantly, they keep us honest. It is not something we claim to be. It is in our DNA.

 

As an organisation, we consider it our mission to create an exciting and rewarding place to work, where our people can be themselves, thrive in positivity and ignite their full potential. A workplace that boosts creativity and innovation, improves productivity, and ultimately drives meaningful results. A workplace that is built on relationships and achieving a purpose that is bigger than us,

Our commitments go beyond an organisational promise. It is in our leadership and managerial ethos to meaningfully partner with our employees, customers and stakeholders with a vision to realise our shared goals.
