- Automate routine administrative tasks utilizing PowerShell scripting.
Required Qualifications
- Currently residing in Singapore with valid working authorization.
- Substantial direct administration experience with Microsoft Exchange 2019 Subscription Edition on-premises, beyond mere support or troubleshooting roles.
- Confirmed track record of planning and executing migrations from on-premises Exchange to Microsoft 365 Exchange Online, including full migration lifecycle involvement.
- Experience working within an in-house corporate IT environment supporting enterprise end users; candidates with solely consulting or project-based backgrounds are unsuitable.
- Excellent ability to collaborate and integrate seamlessly within an established team dynamic.
Technical Knowledge and Skills
- Proficiency with Microsoft Entra ID services, including identity & access management features like Conditional Access, MFA, RBAC, and Privileged Identity Management.
- Familiarity with Microsoft Azure and Azure Stack for cloud administration.
- Expertise in federated authentication and single sign-on technologies such as OIDC, OAuth 2.0, and SAML.
- Administration experience in Microsoft 365 services, specifically Exchange Online, and preferably SharePoint and Teams.
