MAIN FUNCTIONS

We are seeking a highly skilled and proactive Microsoft 365 Administrator to manage and support our company’s Microsoft 365 environment. This role is critical in ensuring the stability, security, and efficiency of our Microsoft 365 services, including Exchange Online, SharePoint Online, OneDrive, Teams, and the underlying Entra ID (Azure AD) identity platform. You will work closely with various IT teams (security, infrastructure, support) and business units to enable collaboration and productivity while maintaining governance and compliance.

TECHNICAL SKILLS

Required

• Microsoft 365 Administration: Proven experience administrating core M365 services – Exchange On Prem and Online, SharePoint/OneDrive, Teams, and Office apps. Solid understanding of how to configure and secure each service.
• Azure AD (Entra ID): Strong hands-on knowledge of Azure Active Directory – user and group management, application enterprise registrations for SSO, Conditional Access setup, and MFA enforcement. Experience with identity synchronization (Azure AD Connect) and basic Azure AD PowerShell/cmdlets.
• Security & Compliance: Familiarity with M365 security centers and compliance centers. Ability to configure and manage DLP policies, retention rules, eDiscovery cases, and view audit logs. Knowledge of Microsoft Defender for Office 365 threat protection and security alert handling.
• PowerShell Scripting: Proficiency in PowerShell for Microsoft 365 administration tasks 14. Able to write, customize, and execute scripts to automate tasks (user license assignments, bulk mailbox changes, report generation, etc.). Bonus if experienced with utilizing the Microsoft Graph API for advanced automation and data queries.
• Migration Tools: Experience with Microsoft 365 migration and integration tools and methods. For example, familiarity with Exchange Online migration methods (cutover/staged/hybrid), SharePoint Migration Tool, or third-party migration solutions (Quest, Sharegate, MigWiz). Understanding the best practices for tenant-to-tenant migration is a plus.
• Troubleshooting Utilities: Skilled in using diagnostic tools and logs to troubleshoot issues (e.g., Message Trace in Exchange, network connectivity analyzers for M365, Microsoft Support and Recovery Assistant, etc.). Ability to analyze PowerShell error output or correlation IDs to pinpoint problems.
• General IT Infrastructure: Good grasp of related infrastructure – Windows Server, DNS, networking basics, how email flow and authentication work – as these often intersect with M365 administration. Understanding of how services like Active Directory (on-prem) link to Azure AD, and how Certificates or network changes might affect M365 services.
• Additional Tools: Familiarity with Microsoft Teams admin center, SharePoint admin center, Exchange Admin Center, Teams Phone System configuration, and Intune (endpoint manager) basics to support device access to M365. Experience with monitoring tools or dashboards for Microsoft 365 usage and performance would be beneficial.
• Office Apps Support: Knowledge of the Office suite (Office 365 Apps) deployment and issues, to support users or deploy Office updates (e.g., via Intune or SCCM).
• Scripting/Programming: Apart from PowerShell, any experience with scripting or lightweight programming (Python, etc.) for data processing, or using APIs for automation, is an asset as it shows ability to extend capabilities of the role
• AI and Emerging Tools: Familiarity with AI-driven features in Microsoft 365, such as the new Microsoft 365 Copilot and related AI services, and the ability to manage and leverage these too. The ideal candidate is comfortable using AI assistants (for example, utilizing Copilot in the admin center to quickly gather insights or generate reports) and stay updated on Microsoft’s AI roadmap to adopt beneficial features early. This includes understanding how to configure AI features in line with organizational policies and monitor their usage to ensure they deliver value responsibly.
• Education: Bachelor’s degree in computer science, Information Technology, or a related field; or equivalent professional experience.
• Experience: 3–5 years of hands-on experience administering Microsoft 365 (Office 365) or similar cloud collaboration platforms in a business environment. Prior experience in IT infrastructure or systems administration is advantageous to provide a strong foundation.

An asset
