Microsoft 365 Architect / Lead Engineer & Administrator

Apex Digital Solutions is a consulting firm specializing in Microsoft services, and they are seeking a Microsoft 365 Architect and Lead Engineer/Administrator to join their team. This role involves leading complex Microsoft 365 migrations, engaging with technical teams and executive stakeholders, and serving as a primary delivery lead across various client engagements.

Responsibilities

• Lead technical workstreams for Microsoft 365 tenant-to-tenant and multi-tenant migrations, GSuite to Microsoft 365 migrations, and Active Directory to Active Directory migrations
• Be a hands-on billable resource, not just an advisor — configuration, scripting, troubleshooting, and implementation are core expectations

• Demonstrate strong ownership and time management across concurrent client engagements
• Document architectures, configurations, and recommendations clearly and consistently
• Partner with Customer Success and Sales teams on scoping, planning, and transition to delivery
• Help evolve Apex Digital’s Microsoft 365 standards, patterns, and delivery playbooks
