The Senior Systems Engineer is responsible for leading and supporting Modern Work migration engagements for customers modernizing collaboration, messaging, identity, and endpoint management platforms. This role works directly with customers and internal delivery teams to assess current environments, define migration strategies, and implement successful transitions across Modern Work workloads including Microsoft Exchange Online, SharePoint Online, Teams, OneDrive, Intune, and Microsoft Entra ID.

The ideal candidate brings strong project delivery skills and hands-on experience planning and executing Modern Work migrations. This individual understands how to move organizations from legacy on-premises, private cloud Microsoft platforms into modern collaboration and productivity environments while balancing user experience, technical risk, security, and compliance requirements. The role requires strong customer communication, collaboration across engineering and project teams, and practical experience with Office 365 tenant-to-tenant migrations, collaboration workloads, identity, and endpoint management. Experience with Microsoft 365 government cloud environments and Microsoft Azure SaaS workloads is strongly preferred.

This position is part of NexusTek’s Professional Services organization, which includes specialized Engineering Practice Teams and a comprehensive Project Management Office. The primary focus of the role is to deliver Modern Work migration consulting and lead technical implementation services throughout the project lifecycle. As business needs require, the Senior Systems Engineer may also support discovery, solution design, migration planning, pre-sales activities, and process improvement initiatives for Modern Work and regulated cloud engagements.

Key Responsibilities:

• Assess legacy and current-state environments and translate business, technical, and compliance requirements into practical Modern Work migration strategies.
• Plan and execute migrations for Exchange Online, SharePoint Online, OneDrive, Teams, and Microsoft Entra ID using Microsoft-native and third-party migration tools.
• Lead tenant-to-tenant and platform modernization projects, including discovery, coexistence planning, pilot migrations, cutover execution, and post-migration stabilization.
• Design and support Modern Work identity, security, compliance, and governance foundations including Conditional Access, authentication, data protection, retention, and administrative controls.
• Lead identity assessment, migration, and integration work across platforms including Google Workspace, Microsoft Entra ID, and Okta, with focus on federation, single sign-on, directory synchronization, and access modernization.
• Implement and support Intune and device management capabilities that align endpoint readiness with Microsoft 365 migration and modernization initiatives.
• Document migration waves, prerequisites, dependencies, testing plans, user communication requirements, rollback considerations, and operational handoff deliverables.
• Support regulated or Security Compliance driven cloud engagements with awareness of Microsoft 365 GCC and GCC High considerations, limitations, and deployment requirements.
• Provide prompt, efficient, detailed, customer-oriented service to NexusTek customers.

Additional Responsibilities:

• Actively drive Modern Work migration projects to successful outcomes by engaging customers and internal teams as a lead engineer and trusted advisor.
• Lead discovery sessions to understand current-state platforms, business objectives, compliance drivers, user impact, and migration dependencies.<
