Senior Microsoft 365 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
  
• Microsoft certifications are welcome but not essential.
