Apex Digital Solutions | Detroit, MI (Hybrid/Remote)

Full‑Time | Client‑Facing | Billable Delivery Role

Apex Digital Solutions is hiring a Microsoft 365 Architect and Lead Engineer/Administrator to join our Microsoft‑focused consulting and managed services team. This is a hands‑on, senior technical role for someone who thrives in complex Microsoft 365 environments, leads large‑scale migrations, and confidently engages with both highly technical teams and executive stakeholders.

This role is critical to continuing to scale our delivery organization and will serve as a primary delivery lead and escalation resource across Microsoft 365 migrations, assessments, security initiatives, support escalations, and advisory engagements.

Clients you will work with range from 250 to 2,500 users across multiple industries and engagement models, including fully managed, co‑managed, advisory, and project-based services.

• 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
