  • Evaluate and implement improvements to Microsoft security and infrastructure platforms.

Technical Leadership & MSP Transition:
  • Act as technical owner for infrastructure and security vendors.
  • Develop plans to transition operational responsibilities from managed service providers to internal IT resources.
  • Validate vendor recommendations and architectural decisions.
  • Identify opportunities to improve service quality, operational efficiency, and cost effectiveness.
  • Provide technical mentorship to engineers and support staff.

Service Delivery & Support:
  • Serve as Tier III escalation resource.
  • Participate in troubleshooting complex user and infrastructure issues.
  • Support major incidents and problem management activities.
  • Contribute to continuous improvement of support processes and documentation.
  • Utilize Jira Service Management and established ITIL-style processes.
Qualifications:
Required:
  • 7+ years of experience in systems, infrastructure, networking, or cybersecurity roles.
  • Experience administering Microsoft 365 environments.
  • Experience with Microsoft Entra ID and identity security.
  • Experience with Microsoft Defender security platforms.
