Comet Consulting Group is a Microsoft-focused managed services and professional services firm based in Strongsville, Ohio. We work with mid-market businesses across managed services, Azure, Microsoft 365, identity, and security. We are a small team — the work you do here is visible, the clients know your name, and you are not spending three years waiting for a real project.

Our delivery values are Ownership, Humility, Discipline, and ROTA (Relationships Over Transactions Always).

We are hiring a Senior Manager for our Modern Work practice. You will own engagements across endpoint management, Exchange Online and messaging, and Microsoft 365 collaboration. Rather than embedding on a single account, you will carry a focused portfolio of client projects, moving through different environments and problems throughout the year.

This is a senior individual contributor role. You will mentor junior and mid-level consultants, set delivery standards, and have real input into how the practice is built as Comet scales. For the right person, this is the on-ramp to practice leadership.

• Lead Exchange Online migrations from on-premises environments, including single-label AD domains, on-prem relay dependencies, and hybrid configurations that need a clean decommission after cutover.
• Design and execute endpoint modernization programs: AD-joined to Entra
  -joined, co-management transitions from Config Mgr to Intune, BYOD scenarios with MAM-only policy design.
• Run content migrations from third-party SaaS platforms and on-prem file servers into SharePoint Online and One Drive — including the pre-migration assessment that finds problems before they become blockers.
• Work through post-merger M365 environments: tenant consolidations, domain cutover sequencing, and cross-tenant mail and content migration.
• Build adoption and change management into every engagement from day one. Technology that does not get used is a failed project regardless of how well it was configured.
• Define success metrics before implementation starts and report against them through close.
• Manage the handoff between delivery services to Comet's managed services or Client SMEs.
• Contribute to proposals and pre-sales where your technical depth makes the engagement credible.

• Give structured feedback to junior and mid-level consultants on your engagements — explain the reasoning, hold the bar, and check whether it sticks.
• Help define what good delivery looks like at Comet: documentation standards, close-out requirements, and client communication expectations.
• Manage practice financial performance and annual budgets.
• Own and advance Comet's Modern Work delivery standards: runbooks, engagement templates, and methodology improvements that outlast the individual engagement.

• Conduct Copilot readiness assessments: oversharing remediation in SharePoint, sensitivity labeling strategy, Entra s reviews, and permission cleanup before enablement.
• Bring a point of view on where the Modern Work stack is heading — particularly around Copilot readiness and the data governance work that gates responsible enablement.
• When you spot a delivery pattern across engagements, write it down. Add it to how Comet does this work, not just how you personally do it.

• 8+ years delivering Microsoft solutions for mid-market or enterprise clients in a client-facing consulting capacity.
• Technical depth across at least two Modern Work pillars (endpoint, messaging, collaboration), with…
