Technical Leader

Colt provides network, voice and data centre services to thousands of businesses around the world, allowing them to focus on delivering their business goals instead of the underlying infrastructure.

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-optimized outcomes, leveraging automation and standardization across all enterprise infrastructure services.

  • Ensure robust governance and security posture for Azure and GCP environments.
  • Collaborate with teams responsible for virtualization (VMware), storage, and networking to ensure seamless integration and performance.
  • 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.
  • Own and manage the relationship with Microsoft, ensuring value realisation, roadmap influence, and full leverage of entitlements.
• On-call
