Centralized Services Systems Administrator

Centralized Services Systems Administrator

Job Overview

We are seeking an experienced and proactive Centralized Services Systems Administrator to support a growing international managed services provider.

This role is focused on proactive infrastructure management, Microsoft cloud administration, security remediation, backup monitoring, automation, and overnight project work. The successful candidate will work independently during US operating hours while collaborating with a broader technical team.

This is not a traditional reactive help desk position. The role requires someone who can identify issues, perform remediation, complete technical projects, and improve recurring processes through scripting and automation.

Key Responsibilities

• Monitor infrastructure, security, backup, and RMM alerts and complete appropriate remediation.
  
• Manage and troubleshoot Microsoft 365, Azure, Entra ID, and Active Directory environments.
  
• Perform Microsoft Windows Server maintenance, patching, troubleshooting, and administration.
  
• Manage backup platforms, including Veeam and cloud-based backup solutions.
  
• Complete server hardware and firmware maintenance tasks.
  
• Perform overnight infrastructure and Microsoft cloud projects.
  
• Complete Microsoft 365 and SharePoint migrations.
  
• Perform email migrations using Proofpoint or similar platforms.
  
• Assist with Entra ID desktop profile migrations.
  
• Support SOC and MDR implementations.
  
• Respond to security incidents, perform remediation, and escalate when necessary.
  
• Use RMM platforms, preferably NinjaOne, to monitor and manage client environments.
  
• Create PowerShell scripts and automation to resolve recurring technical issues.
  
• Document completed work, technical processes, and remediation steps.
  
• Manage tickets accurately through a PSA platform such as ConnectWise or Halo.
  
• Work independently, prioritize competing responsibilities, and meet project deadlines.
  
• Assist with mentoring junior technicians and improving centralized services processes where required.

• Experience using an RMM platform in an MSP or multi-client environment.
