Why we need this role
We are seeking an experienced technical leader to oversee Enterprise Infrastructure Services, acting as both a manager and a hands‑on contributor. This role is responsible for managing Windows Server, VDI, Citrix, Microsoft 365, and cloud environments (Azure and GCP). The role requires a strategic thinker who can also contribute technically as a player‑manager, overseeing and delivering critical infrastructure services while shaping long‑term strategy and roadmaps. You will lead a team of approximately 10 engineers across regions, own managed service outsource agreements, and drive both financial performance and service outcomes. In addition to leadership responsibilities, you will act as a technical SME, providing hands‑on support for complex implementations and escalations.
While not directly responsible for virtualization, storage, and networking, the role requires a strong working knowledge of these areas to ensure seamless integration. The successful candidate will take ownership of technical solutions and assume responsibility for delivering secure, resilient, and cost‑optimised outcomes, leveraging automation and standardisation across all enterprise infrastructure services.

- Maintain compliance with security and regulatory standards.
Project Delivery & Vendor Relationships
- Lead infrastructure projects from design through implementation.
- Collaborate with cross‑functional teams to deliver scalable, secure, and resilient solutions.
