IT Operations Principal (M365 Engineer)
About the role
Automate the toil away
Kill the repeat tickets —
Build self-service —
Measure what you removed —
we care about the tickets that stopped happening, not the ones you closed quickly.
- Get Copilot ready — permissions hygiene, oversharing remediation, and sensitivity labeling with security and compliance, then agents and pilots where a team has a real problem worth solving.
Treat the tenant like a platform
Configuration as code —
Ship changes safely —
Documentation and roadmap
Keep the core solid
The forward-looking work only earns trust if the fundamentals hold, and the people we support feel well served day by day. A meaningful share of the role is still hands-on operations:
- Exchange Online and Entra ID operations — mail flow, connectors, transport rules, and email authentication (SPF, DKIM, DMARC); Conditional Access, MFA and passwordless rollouts, SSO integrations, directory sync, and privileged access.
- Tier-3 escalation for M365 issues — root cause analysis that produces a permanent fix — plus a shared on-call rotation and occasional maintenance windows.
We care more about how you think than about the exact boxes you tick. If you meet most of this and are genuinely interested in the rest, apply.

Bonus Points
- Hands-on work with Copilot Studio, declarative agents, or Graph connectors.
- Infrastructure-as-code experience (Bicep, Terraform, Azure Automation) or CI/CD applied to tenant configuration.
- Defender for Office 365 or Defender for Identity.
- Hybrid Exchange or migration experience, including tenant-to-tenant moves.
- Certifications such as MS-102, SC-300, or AZ-104 — useful signal, not a requirement.
- Experience in a regulated environment with formal audit requirements.
Working Here
- Fully remote, with a preference for candidates in the Eastern or Central time zone so there is real overlap with the team.
- Less than 25% travel for occasional team meetings and site visits.
- On-call rotation shared across the team — nobody carries it alone.
- Education: a degree in a technical field is welcome, and equivalent hands-on experience is equally welcome.
