Principal Recruiter within Defence, Space & Public Safety
Role Overview
Our client, a UK-based organisation supporting safety-critical systems, is strengthening its local infrastructure capability. Recent operational and audit reviews have identified risks related to under‑resourcing, ageing platforms, and concentration of system knowledge and access.
Key Responsibilities
* Own and maintain UK-based virtualisation and storage platforms (Azure, Hyper‑V, KVM, VMware).
* Plan and deliver patching, refresh, and upgrade cycles for servers and hypervisors, including legacy environments.
* Manage and optimise Azure resources, including virtual machines, networking, cost control, and backup policies.
* Implement, operate, and monitor storage solutions (SAN/NAS/iSCSI, backup, replication) to ensure availability and data integrity.
* Support and maintain on‑premises hardware, including physical servers, hypervisors, and critical appliances.
* Ensure audit readiness and compliance for systems subject to UK access and data residency restrictions.
* Maintain accurate documentation, asset inventories, and configuration records.
* Act as the local hands‑on engineer for hardware replacements, vendor coordination, and emergency interventions.
* Collaborate with international and offshore teams to improve service consistency, ticket handling, and project delivery.
* Contribute to capacity and performance planning for critical UK systems.
* Provide input into automation, standardisation, and repeatable build and patching processes.
Required Experience and Skills
* 5+ years’ experience in systems engineering, virtualisation, or infrastructure operations.
* Strong hands‑on experience with Microsoft Azure (VMs, storage, networking, RBAC, policies).
* Proven expertise with at least one major virtualisation platform (Hyper‑V, KVM, or VMware), including clustering and migrations.
* Experience managing enterprise storage solutions (RAID, SAN, NFS, iSCSI) and backup/restore processes.
* Solid administration skills across Windows Server and Linux (RHEL/Ubuntu).
* Working knowledge of automation and scripting using PowerShell, Bash, or Ansible.
* Good understanding of network fundamentals (VLANs, routing, firewalls, VPNs).
* Experience working in restricted, regulated, or air‑gapped environments is advantageous.
* Strong documentation discipline and familiarity with formal change management processes (e.g. ITIL).
* Ability to work autonomously while collaborating effectively with geographically distributed teams.
* Experience with Azure Arc, Defender for Servers, and hybrid cloud integrations.
* Familiarity with monitoring platforms such as Zabbix or Prometheus.
* Exposure to enterprise backup and disaster recovery tools (e.g. Veeam, Commvault).
* Relevant certifications (AZ‑104, RHCSA/RHCE, VMware VCP, or similar).
* Good understanding of network security concepts, including segmentation, ACLs, and NAC.
