• Identify manual administrative tasks and automate them using scripting (Python/Bash/Power Shell) or workflow tools to reduce toil.
• Maintain high-quality technical documentation (Confluence) for system configurations and processes, and mentor junior team members to improve their technical capability.
• Support the maintenance of security standards by ensuring timely patching, vulnerability management, and correct configuration of security tools.

• Deep understanding of Entra  (Azure AD) and Google Workspace administration or similar, including SSO, SAML, OIDC, and Conditional Access policies.

• Experience configuring and troubleshooting networks (Firewalls and Switches).

• Experience managing and supporting enterprise SaaS tools (Slack, Jira, Zoom, etc.).
• Strong ability to investigate and resolve complex technical issues across OS, Network, and Application layers.
• Ability to write and maintain scripts (Bash, Python, or Power Shell) to automate administrative tasks and API interactions.
• Strong interpersonal skills with a customer-focused approach, able to explain technical concepts to non-technical stakeholders.

• Practical experience with Dell Power Edge servers and UPS management.
• Experience administering Linux servers in a production environment.
• Familiarity with containerisation (Docker/Kubernetes) concepts.
