Job Description - Microsoft 365 Security Escalation Engineer
SUMMARY
We’re seeking a Senior Microsoft 365 engineer to operate behind the scenes, focusing on security, complex escalations, and assigned project work. This is not a frontline, not client-facing, and not a leadership role. It’s designed for someone who prefers deep technical work over meetings and noise. You’ll work as a back-of-house escalation specialist, reporting to the Operations Manager. Your time will be split approximately:
60% Microsoft 365 security & escalation BAU
40% planned project delivery (e.g. SharePoint and security uplift work)
There is no on-call, no after-hours, and no presales or account management.
JOB RESPONSIBILITIES
Resolve complex Microsoft 365 security and identity issues escalated from the service desk
Design, adjust and troubleshoot:
Entra ID / Azure AD (MFA, Conditional Access, access models)
Microsoft Defender for Office 365
Secure mail flow and phishing protections
Deliver assigned projects such as SharePoint Online migrations and tenant security uplift
Perform root-cause analysis and document outcomes for operational handover
Improve internal standards, runbooks and repeatability across client environments
QUALIFICATIONS
Strong hands-on experience with Microsoft 365 in an MSP or multi-tenant environment
Proven capability with Entra ID, Conditional Access and M365 security tooling
SharePoint Online administration and migration experience
Ability to work independently on assigned tasks with minimal supervision
Clear documentation and practical problem-solving skills
