Interim Head of Infrastructure Transformation Program. Job in London LilyLifestyle Jobs

We are seeking an experienced Interim Head of Infrastructure & Service Management to play a pivotal role in a major IT transformation programme for a FTSE 250 organisation. The business has ambitious growth plans and has completed a high-level IT maturity assessment, strategy and target operating model. The next critical step is to define the detailed end-state, articulate a credible transformation journey, and secure Board approval and investment to execute it.

As a core member of the IT Transformation leadership team, you will lead the Infrastructure & Service Management workstream, defining and delivering the robust, scalable and secure infrastructure and service foundations required to enable future growth and "silent running" operations.

We're looking for a candidate with a strong technical foundation in infrastructure, including networks, servers, cloud platforms, databases, backup and recovery, and end-user devices. The ideal person will be confident engaging with technical detail, able to challenge assumptions, and capable of defining and articulating what best practice looks like across the infrastructure landscape.

Key responsibilities include:

• Assessing the current infrastructure and service management landscape across Group and Divisions, including networks, cloud and on-prem platforms, end-user environments, service desk and ITSM processes, tooling, assets and licensing.
• Defining the target state for infrastructure, service management and operational resilience, covering service architecture, operating model, processes, tooling, observability and recovery capabilities.
• Establishing clear principles for standardisation, automation, cloud and hybrid adoption, and determining which services should be insourced or outsourced.
• Reviewing third-party service providers and contracts to identify performance, cost, risk and structural issues, and defining approaches to re-tendering, renegotiation or transition where required.
• Designing end-to-end service definitions, ownership, SLAs/OLAs, governance and interaction models across Group and Divisions, aligned to a federated IT model.
• Working closely with Cyber, Architecture, Applications and Data leadership to ensure alignment across identity and access implementation, platform dependencies, governance and demand management.
• Producing a clear transformation roadmap and implementation plan, including transition states, dependencies, costs, benefits and investment requirements to support executive and Board decision making.

The successful candidate will have a strong track record leading enterprise-scale infrastructure and service management transformations in complex environments. You will be comfortable operating at executive and Board level, while retaining deep technical credibility across modern infrastructure architectures, cloud and hybrid platforms, enterprise connectivity, ITSM tooling, automation, observability, and operational resilience. Experience in manufacturing or other security-sensitive industries would be advantageous, along with a working knowledge of both Operational Technology (OT) and Information Technology (IT) environments.
