Description:

Job Summary: We are seeking an Infrastructure Engineer to support a significant infrastructure insourcing programme, with an initial focus on discovery and documentation of the existing infrastructure estate, followed by hands-on support across Business As Usual (BAU) operations and project delivery.

The role will cover a broad set of infrastructure technologies including Windows and Linux platforms, virtualisation, monitoring, end user services, and security tooling. The successful candidate will play a key role in capturing knowledge from incumbent suppliers, supporting the transition to an in-house operating model, and contributing to the ongoing stability, security, and evolution of the platform estate.

This is a hands-on engineering role requiring strong technical breadth, a proactive approach to problem solving, and the ability to operate across multiple technologies within a complex enterprise environment.

Key Responsibilities:

• Support the infrastructure insourcing programme, including discovery, analysis, and documentation of the existing infrastructure estate across on‑premises and cloud environments.
• Produce and maintain high‑quality technical documentation, including system configurations, process documentation, support runbooks, and architectural diagrams.
• Provide hands‑on engineering support for BAU operations, including incident resolution, service requests, and operational improvements across supported platforms.
• Deliver infrastructure‑related changes and project work, ensuring adherence to change management processes, security standards, and architectural principles.
• Support and maintain core infrastructure services including Windows, Linux, Active Directory, DNS, and DHCP.
• Administer and support virtualisation platforms such as VMware and/or Hyper‑V.
• Support end user and application delivery platforms such as Citrix and SCCM.
• Manage and support infrastructure monitoring tooling (e.g. SCOM, SolarWinds, Splunk or similar), ensuring effective alerting, visibility, and operational insight.
• Support backup and recovery platforms (e.g. Rubrik and/or NetBackup), ensuring data protection and recoverability requirements are met.
• Collaborate with network, security, and application teams to support wider infrastructure and service delivery initiatives.
• Support security compliance and audit activities, including evidencing controls and supporting remediation activities where required.
• Work closely with third parties and incumbent suppliers during transition activities to ensure effective knowledge transfer.
• Identify, recommend, and implement service improvements to enhance the stability, security, and efficiency of the infrastructure estate.
• Assist with platform upgrades, patching, and lifecycle management activities across infrastructure components.
• Contribute to the continuous improvement of infrastructure processes, tooling, and standards.

Required Skills & Experience:

• Proven experience working as an Infrastructure Engineer within a complex enterprise environment.
• Strong experience across Windows and/or Linux server environments.
• Experience supporting core infrastructure services such as Active Directory, DNS, and DHCP.
• Experience with virtualisation platforms (VMware and/or Hyper‑V).
• Experience supporting infrastructure monitoring tools (e.g. SCOM, SolarWinds, Splunk or similar).
• Experience with backup and recovery solutions (e.g. Rubrik and/or NetBackup).
• Experience supporting infrastructure services across both BAU and project‑based delivery.
• Good scripting ability (e.g. PowerShell, Bash, or similar) to support automation and operational efficiency.
• Good understanding of infrastructure security principles and interaction with security tooling.
• Good understanding of database platforms and their infrastructure dependencies.
• Strong documentation skills, with experience capturing as‑is environments and producing clear, structured technical documentation.
• Ability to work effectively during transition and change programmes, including engagement with third‑party suppliers.
• Excellent problem‑solving, communication, and stakeholder engagement skills.
• Experience with Citrix environments, CyberArk (or similar privileged access management tooling), and SCCM or equivalent endpoint management platforms would be advantageous.
• Experience working within large, regulated, or critical national infrastructure environments is beneficial.
• Experience supporting hybrid on‑premises and cloud‑based environments is beneficial.
• Familiarity with IT service management processes and formal change control frameworks is desirable.

Desirable:

• Ideally, candidates will already hold Security Check (SC) clearance.
