Position Overview

Novatae Risk Group is seeking a Sr. IT Systems Administrator to serve as the technical owner of our Microsoft 365 ecosystem and the broader portfolio of enterprise systems and SaaS platforms that run the business, as well as the hands-on lead for the platform migrations and system integrations that follow our mergers and acquisitions. Reporting to the CTO, this role combines deep M365 administration with day-to-day ownership of the collaboration, service management, and productivity applications relied on across the organization, in addition to new technologies and systems as they are introduced.

The Sr. IT Systems Administrator will own the design, security, governance, and day-to-day operation of Novatae’s M365 tenant—Entra ID, Intune, Purview, Exchange Online, Defender, and the Conditional Access and compliance policies that hold it together in addition to the various enterprise systems used by the organization, adhering to best practices and policies established by Novatae’s parent company, World Insurance Associates. As Novatae continues to grow through acquisition, this role will lead tenant-to-tenant, and platform to platform migrations and the consolidation of acquired IT environments into the Novatae landscape, from due-diligence discovery through cutover and decommissioning.

This role must possess a high-level of skills in design, development, analysis and technical expertise and works closely with the Manager of IT Infrastructure and the IT support team to keep systems secure, reliable, and well-documented, while advancing the organization’s strategic initiatives. It is well suited to a hands-on administrator who wants broad ownership across a modern cloud-first environment.

• Licensing & lifecycle: Track licensing, renewals, and utilization across all systems, right-sizing entitlements and coordinating onboarding/offboarding across every platform.

M&A Integration & Platform Migration

• Migration leadership: Lead tenant-to-tenant and platform migrations for acquired entities—mailboxes, OneDrive, SharePoint, Teams, identities, and endpoints—end to end, from planning through validation and cutover.
