This is a senior, hands-on engineering role requiring someone who can troubleshoot complex Microsoft 365 issues, lead technical improvements and migrations, automate administration, and work across infrastructure, identity, networking, and cybersecurity teams.

Administer and support OneDrive for Business, including synchronization, sharing, permissions, storage, migration, and user-related issues. Support Microsoft Teams and its integration with Exchange, SharePoint, OneDrive, and the broader Microsoft 365 ecosystem.

Partner with cybersecurity and identity teams to implement appropriate security, compliance, authentication, and access controls. Support Microsoft Entra ID integrations, Single Sign-On, Multi-Factor Authentication, and Conditional Access as they relate to Microsoft 365 services. Use Microsoft Purview and related capabilities to support information governance, retention, data protection, and compliance requirements. Develop and maintain PowerShell automation for Exchange, SharePoint, OneDrive, Microsoft 365 administration, reporting, and operational processes. Monitor service health, capacity, performance, and usage across Microsoft 365 services and proactively identify opportunities for improvement. Lead or support tenant-level configuration changes, migrations, platform upgrades, and service enhancements. Provide Tier 3 escalation support for complex Microsoft 365 messaging and collaboration issues. Perform root-cause analysis and develop sustainable solutions for recurring service issues. Collaborate with infrastructure, networking, identity, security, and application teams to resolve complex cross-platform issues. Develop and maintain technical documentation, architecture diagrams, configuration standards, operational procedures, and support documentation. Participate in disaster recovery, business continuity, and technology lifecycle initiatives. Participate in on-call and after-hours support when required. ABOUT THE REQUIREMENTS Bachelor's degree in Information Technology, Computer Science, or a related discipline, or equivalent professional experience. 8+ years of enterprise IT infrastructure or systems engineering experience, with significant experience supporting Microsoft 365 technologies. Deep hands-on expertise with Microsoft Exchange Online and enterprise Exchange environments.

Strong hands-on experience administering and supporting SharePoint Online in a large enterprise environment. Strong hands-on experience with OneDrive for Business, including permissions, sharing, synchronization, migration, and troubleshooting. Strong understanding of how Exchange, SharePoint, OneDrive, and Teams interact within the Microsoft 365 ecosystem.

Advanced PowerShell scripting skills for Microsoft 365 administration, automation, reporting, and troubleshooting. Experience with Microsoft Purview, retention policies, information governance, and/or related Microsoft 365 compliance capabilities. Strong understanding of enterprise messaging, collaboration, identity, security, and data-governance concepts. Demonstrated experience troubleshooting complex Microsoft 365 issues across multiple integrated technologies. Experience supporting migrations, upgrades, consolidation, or modernization of enterprise Microsoft collaboration environments. Excellent analytical, troubleshooting, and problem-solving capabilities. Strong communication and collaboration skills with the ability to work effectively across infrastructure, security, identity, and business teams. Ability to manage multiple priorities while supporting critical enterprise services. PREFERRED QUALIFICATIONS Microsoft certifications related to Microsoft 365, Exchange Online, Azure, or Microsoft identity and security technologies. Experience supporting Microsoft 365 within a large, globally distributed enterprise. Experience with large-scale Exchange migrations or hybrid-to-cloud modernization initiatives. Experience with SharePoint and OneDrive migrations, tenant consolidation, or large-scale content-management initiatives. Experience with Microsoft Graph and automation of Microsoft 365 services. Experience with enterprise backup, recovery, archiving, or continuity solutions for Microsoft 365. Knowledge of security and compliance frameworks including NIST, ISO 27001, or SOX. Experience working within regulated healthcare, medical technology, life sciences, or similarly controlled environments. Experience supporting large-scale Microsoft 365 modernization and transformation initiatives.
