About the Role
The Head of Infrastructure Services owns the full lifecycle of core infrastructure and network provision, covering on-premises and cloud environments, WAN/LAN, and remote access.
The role reports directly to the CIO and carries genuine ownership: the successful candidate will set the roadmap, hold budget accountability, and act as the senior point of governance for the organisation's infrastructure MSPs.
This is not a hands-on engineering role. It is a leadership and governance position for someone who has already done the technical work and now wants to own strategy, vendor performance, and financial accountability at a senior level.
Key Responsibilities
Infrastructure & Network Leadership
- Own the end-to-end lifecycle, performance, and roadmap of infrastructure and network services across on-premises and cloud environments, WAN/LAN, and remote access.
- Maintain an authoritative asset inventory and CMDB aligned with ITIL practices.
- Own resilience planning, including backup, disaster recovery, and high-availability architecture, with regular testing built in.
- Set documentation standards for every infrastructure service, covering ownership, lifecycle status, support model, and known limitations, and enforce a periodic review and attestation process.

- Lead technical design assurance reviews for solutions delivered by MSPs or internal teams.
Roadmap & Service Planning
