We are Systematix and we are currently looking for a Senior Microsoft 365 Systems Engineer – Exchange & Collaboration to support the design, administration, and ongoing modernization of enterprise Microsoft messaging and collaboration services for one of our Medical Technology partners.

ABOUT THE PROJECT

Our client is a global leader in science and technology, supporting critical business operations across a highly distributed global enterprise. As part of its ongoing investment in modernizing enterprise IT services, the organization is seeking an experienced Microsoft 365 engineer with deep expertise in Exchange, SharePoint, and OneDrive.

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.

- 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.
