• Check and confirm backups are working correctly and manage tape rotation regularly.
• Perform test restores to ensure data recovery works in line with industry cybersecurity guidelines, supporting disaster recovery processes.
• Assist in building, modifying or removing server environments as needed, applying patches and firmware updates in line with cybersecurity frameworks.
• Support the implementation of cybersecurity controls and monitoring tools and assist with regular security reviews.

• Work with vendors to support national and international telecommunications and assist in monitoring network security and redundancy.
• Assist with infrastructure-related IT projects and uplift initiatives aligned with cybersecurity frameworks and Industry 4.0 improvements.
• Provide guidance and informal mentoring to the IT Systems Analyst and other junior technical staff.

About You

You'll bring strong practical knowledge of infrastructure, cybersecurity and end-user technology, and enjoy working across a busy manufacturing environment to keep systems reliable and secure.

You'll also bring:

• 3+ years' experience in a systems administrator role within a similarly sized environment.
• Experience providing L2/L3 escalation support and resolving issues passed up from a helpdesk function, including root-cause analysis of recurring problems.
• Solid working knowledge of Windows Server, Active Directory and Entra ID, including group policy, DNS and DHCP.
• Practical experience with virtualisation platforms such as VMware or Hyper-V, including building, maintaining and troubleshooting virtual environments.

• Solid understanding of cybersecurity frameworks and principles, such as the Essential Eight, NIST or ISO 27001.
• Experience using and managing backup software, such as Veeam.
• Familiarity with cloud platforms and tools, including Office 365, AWS and Azure.
• Strong interpersonal skills, sound judgement and the ability to work independently, managing time and tasks with minimal supervision.
• Experience working as part of a project team on infrastructure or systems implementations.

Desirable Skills

• Industry-recognized certifications or tertiary-level qualifications in IT or a related field.
• Formal cybersecurity certification or training; demonstrated experience applying frameworks such as the Essential Eight will also be considered.
