Key expectations:

You will be responsible for delivering predictable, high‑quality outcomes across complex infrastructure and cloud projects in a global, matrixed environment.

• Drive project planning including scope, timeline, resource planning, budgets, and measurable outcomes.
• Manage delivery across internal teams and external vendors, ensuring accountability and quality.
• Mitigate project risks and dependencies, escalating proactively when delivery or operational stability is at risk.
• Ensure compliance with security, privacy, and architectural standards across all project phases.
• Coordinate technical discussions with architects, engineers, and product stakeholders to ensure feasible and high‑quality solutions.
• Prepare executive‑level reporting, summarizing progress, decisions, risks, and financials.
• Improve delivery processes, driving standardization, documentation, and continuous improvement across infrastructure programs.

• Oversee transition to operations, ensuring complete handover of support documentation and operational readiness.

Who you’ll work with:

• Country and Group leadership and stakeholders
• Programme leadership and stakeholders
• Project teams inside and outside of IT Department
• Infrastructure and Application Owners
• Finance Team

Key qualifications:

• 10+ years of IT project management experience with a focus on infrastructure, cloud, or enterprise platforms.

• Strong financial management skills (forecasting, capex/opex, vendor contracts).

• Expertise in project management methodologies (Waterfall, Agile, hybrid).

• Advanced communication skills with the ability to present to senior leadership.

• Solid understanding of:
  - Cloud platforms (Azure, AWS, or GCP)
  - Servers, storage, virtualization
  - ITSM and operational readiness

   

Nice to have:

• Background in cloud migration programs or data center exit initiatives.
