About Comet

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).

The role

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.

What you'll do

Delivery

  • 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 ID-joined, co-management transitions from ConfigMgr 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 OneDrive — 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.

Mentoring and practice development

  • 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.

Strategic contribution

  • Conduct Copilot readiness assessments: oversharing remediation in SharePoint, sensitivity labeling strategy, Entra ID access 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.

What we're looking for

  • 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 enough range across all three to lead any of them.
  • Secondary depth in Entra ID and Microsoft security — you can guide a client conversation on identity and know when to escalate.
  • Experience running projects: scope management, stakeholder communication, and the ability to deliver bad news without losing the relationship.
  • Post-merger M365 work in your history — tenant consolidation, cross-tenant collaboration, or M&A IT integration.
  • A consistent method for running a project, and the ability to explain it.
  • Microsoft certifications are a plus — we will support you in earning them if you don't have them yet.

What sets you apart

  • You have grown something others depended on: a practice, a team, a capability.
  • You have done Copilot readiness work: oversharing cleanup, data classification, sensitivity labeling — and can describe what actually gates a responsible rollout.
  • Experience integrating with MSP or MSSP environments is a differentiator.
  • You have worked across more than one major cloud platform and can speak to the tradeoffs.
  • If you have built anything in Copilot Studio or led an M365 Copilot adoption program for a mid-market client, say so in your application.

What Comet offers

  • Base salary of $135,000 – $185,000, depending on experience and qualifications
  • Annual performance bonus
  • Microsoft certification reimbursement
  • Full benefits package (health, dental, vision, 401k)
  • Remote with occasional client travel roughly once per quarter
  • Direct path to practice leadership as Comet scales
