Cloud & Infrastructure Domain Lead

The Cloud and Infrastructure lead is a senior technical leadership role within Deloitte Belgium's IT department, reporting directly to the CIO. The post-holder is both the engineering team lead and the formal service owner for all cloud infrastructure services - accountable not just for how the infrastructure is built and run, but for the service experience, reliability commitments, and business value delivered to approximately 5,500 users and all IT workload teams that depend on it. Following the completion of Deloitte Belgium's full cloud migration and datacentre decommission, the focus of this role is to mature, optimise, and govern the cloud estate. The Head of Cloud Infrastructure will lead a team of cloud and platform engineers, drive a strong SRE culture, and act as the primary interface between infrastructure capabilities and the broader IT service portfolio. They will report directly to the CIO and operate as a key member of the IT leadership community. Cloud Platform Engineering

• Define and publish service standards, including availability targets, support tiers, and onboarding requirements for consuming teams.
• Ensure all cloud infrastructure components are accurately represented in the CMDB, with clear ownership, lifecycle status, and dependency mapping.

SLA / SLO Governance

• Set, negotiate, and own Service Level Agreements (SLAs) and Service Level Objectives (SLOs) for all cloud infrastructure services - including availability, performance, and recovery targets.
• Establish and manage error budgets as the primary mechanism for balancing reliability and velocity across the platform.
• Report on service performance against SLAs/SLOs to the CIO and IT leadership on a regular cadence, with clear root cause analysis where targets are missed.

Demand & Roadmap Management

• Own the cloud infrastructure service roadmap, translating business demand, technology evolution, and platform debt into a prioritised, funded plan.
• Act as the intake point for consuming teams requiring new or changed infrastructure services, qualifying demand and managing expectations through transparent backlog visibility.
• Collaborate with the CIO, Development and Configuration Lead, and Security & Risk Lead to ensure the platform roadmap is aligned to the wider IT TOM and strategic direction.

Cost & FinOps
