The ideal candidate is comfortable owning both operational support and security operations, thrives in a fast-paced environment, and has deep familiarity with the Microsoft 365 ecosystem, including Intune, Defender for Endpoint, Azure AD, and Exchange.

  • Manage Azure Active Directory (Entra ID), including conditional access, MFA, and SSO integrations.
  • Configure and maintain Exchange Online, including mailboxes, shared mailboxes, distribution lists, and mail flow rules.
  • Administer SharePoint Online and OneDrive policies and permissions.
  • Monitor Microsoft 365 service health and manage incident response.

Endpoint and device management:

  • Take ownership of Microsoft Intune for Windows, macOS, iOS, and Android devices.
  • Build and maintain device compliance policies, configuration profiles, and deployment rings.
  • Manage application packaging and deployment through Intune.
  • Support Autopilot provisioning and device onboarding using Intune and Apple Business Manager.
  • Administer and troubleshoot IT peripherals.

Security operations:

  • Manage Microsoft Defender for Endpoint, including onboarding, policy configuration, alert triage, and remediation.
  • Monitor Microsoft Defender XDR for threats, vulnerabilities, and incidents.
  • Administer Microsoft Purview for data classification, data loss prevention, and compliance policies.
  • Manage Exchange Online Protection, including anti-spam, anti-phishing, and quarantine policies.
  • Maintain tenant allow/block lists and alert policies in Microsoft Defender.
  • Conduct periodic vulnerability assessments and track remediation through Defender Vulnerability Management.
  • Support security awareness initiatives, including phishing simulations.

Infrastructure and cloud:

  • Manage Azure resources, including subscriptions, resource groups, and identity and access management.
  • Administer Azure AD App Registrations and enterprise application integrations.
  • Support Logic Apps, Azure Communication Services, and automation workflows.
  • Monitor infrastructure health and optimise cloud costs.
  • Take ownership of backup and disaster recovery strategy, including Carbonite and Azure-native backup solutions.

IT operations and helpdesk:

  • Serve as the escalation point for daily IT support requests across the organisation and its products.
  • Manage IT ticketing and helpdesk operations through Jira Service Management.
  • Administer third-party SaaS platforms, including HubSpot, Adobe, Business Central, Carbonite, and Keeper.
  • Maintain the IT asset inventory and procurement lifecycle.
  • Manage vendor relationships and SaaS licence renewals.
  • Document processes, runbooks, and IT policies in Confluence.

  • Lead IT infrastructure projects from initial scoping through deployment.
  • Build and maintain automation workflows using Power Automate and Azure Logic Apps.

  • Support onboarding and offboarding workflows, ensuring timely access provisioning and removal.

What we expect from you:

  • At least 2 years of experience in a System Administrator or IT Administrator role.
  • Experience independently managing a Microsoft 365 environment, including Exchange, SharePoint, Teams, and Azure AD.

  • Experience with Jira and Confluence.
  • Familiarity with HubSpot, Business Central, or similar SaaS platforms.
  • Experience with Logic Apps, Power Automate, or other automation tools.
