• Maintain a 3–5 year security architecture roadmap with budget requirements to prevent future cyber‑security attacks.
  
  
• Support the Architecture Working Committee (AWC) and support the periodic request of the architecture principles related to information security.
  
  
• Support the AI working group and the definition of “security guardrails” as part of the Responsible AI initiatives.
  
  
• Support the network standardisation activities of the GSMA Fraud and Security Group (FASG).
  
  
• Assist with management of divisional budgets in line with business objectives and facilitate forecasting.
  
  
• Manage project initiative budgets in line with business objectives.
