Microsoft 365 Architect

We are proactively seeking an experienced Microsoft 365 Architect / Engineer to support an upcoming modernization initiative for a client transitioning from Google Workspace to Microsoft 365. This engagement is ideal for a senior-level professional who enjoys owning the architecture, configuration, and best-practice guidance for a Microsoft environment from the ground up.

Unlike large implementation projects that rely on multiple consultants, this client is looking for one highly capable expert who can take ownership of the Microsoft 365 tenant, finalize the configuration, and ensure the environment is designed correctly before migration and user rollout begin. The ideal candidate will combine deep technical expertise with strong advisory skills, helping guide the client through architecture decisions, governance standards, and long-term platform strategy.

In this role, you will help build a secure, well-structured, and modern Microsoft 365 environment, preparing the tenant for data migration, collaboration adoption, and end-user training. You will partner with stakeholders to define best practices across identity, security, collaboration, and device management while ensuring the platform is ready for daily operations.

Key ResponsibilitiesLead the configuration and optimization of the Microsoft 365 tenant, including Entra ID (Azure AD), identity structure, MFA, Conditional Access, and Intune device management policies.

Establish security, governance, and compliance baselines aligned with Microsoft best practices, including tenant architecture, identity standards, and licensing optimization.

Design the SharePoint Online architecture (sites, libraries, permissions) to support the migration of approximately 6TB of Google Workspace shared drive data by a third-party migration vendor.

Provide guidance on Microsoft Teams rollout and calling strategy, helping the organization transition from existing Avaya and RingCentral systems over time.

Ensure the tenant environment is stable and properly configured prior to end-user training and organizational rollout.

Serve as the technical lead and advisor for the Microsoft 365 environment, providing clear recommendations, best practices, and architectural guidance throughout the modernization effort.
