Principal Microsoft Enterprise Architect

Position Summary

The Client is seeking a Principal Microsoft Enterprise Architect to define, govern, and evolve the enterprise-wide technology architecture across its Microsoft ecosystem and broader digital landscape.

This individual will serve as the senior architectural authority across the enterprise, responsible for ensuring that Microsoft technologies, cloud platforms, business applications, data, AI capabilities, integrations, and custom applications operate as a cohesive and scalable technology ecosystem.

The role will span the full Microsoft technology landscape, including Microsoft Azure, Microsoft 365, Teams, Exchange/Outlook, Dynamics 365 Finance & Operations, Dynamics 365 Customer Engagement, Power Platform, Microsoft Fabric, Copilot and AI services, as well as custom applications, APIs, integrations, and third-party platforms.
