What is a systems administrator?

Systems Administrators, often called SysAdmins, are IT professionals responsible for managing, maintaining, and supporting computer systems and networks within an organization. Their duties include installing hardware and software, monitoring system performance, troubleshooting technical issues, and ensuring system security and data integrity. They play a key role in minimizing downtime, performing regular backups, and updating systems to keep an organization's IT infrastructure running smoothly.

What does a systems administrator do?

The primary duties of a system administrator are to install, update, and maintain computer systems while managing user access regimes. As a systems administrator, you have administrative privileges to change settings, install or remove software, and access security functions unavailable to normal users. A systems administrator might oversee multiple machines at once, or even an entire network. You provide technical support to users who are experiencing problems and collaborate with network administrators to ensure the continued performance of the network. As a systems administrator, you determine the level of access a user has to network information and what operations they can perform, limiting users to only what they need to perform their job.

What are the key skills and qualifications needed to thrive as a systems administrator, and why are they important?

To thrive as a Systems Administrator, you need a solid understanding of operating systems, network management, and security protocols, typically supported by a relevant degree or certifications like CompTIA Network+, Microsoft Certified Solutions Associate (MCSA), or Linux+. Familiarity with tools such as Active Directory, virtualization platforms, and configuration management systems is essential. Strong problem-solving abilities, attention to detail, and effective communication skills help you respond quickly to issues and work collaboratively with IT teams. These skills and qualifications are crucial for maintaining system reliability, minimizing downtime, and ensuring secure, efficient IT operations.

What are some typical challenges a systems administrator faces when managing both on-premises and cloud infrastructure?

Systems Administrators often juggle responsibilities across on-premises servers and cloud-based platforms, which can introduce challenges such as ensuring seamless integration, maintaining consistent security policies, and managing access controls. Balancing updates, backups, and monitoring tools across different environments requires strong organizational skills and up-to-date technical knowledge. Effective communication with other IT team members and end users is also crucial for troubleshooting and minimizing downtime.

What is the difference between Systems Administrator vs Network Administrator?

Work EnvironmentManage servers, operating systems, and enterprise applicationsFocus on network infrastructure, routers, switches, and connectivity
Employer & Industry UsageIT departments across various industries, supporting internal systemsOrganizations with complex networks, telecom, and internet service providers

IT Systems Administrator – Azure Infrastructure

Knoxville, TN | Hybrid

A well established organization is seeking an IT Systems Administrator III to oversee and operate mission-critical Azure infrastructure within a regulated environment. This role carries direct responsibility for infrastructure stability, security, and reliability across production systems.

The ideal candidate brings hands on Azure IaaS experience, sound infrastructure judgment, and a strong security mindset. This is an operations focused role for professionals accustomed to owning production environments—not end user support.
Must-Have Experience

  • Strong Azure IaaS hands-on experience (VMs, networking, storage, backups) 
  • Experience supporting production infrastructure environments 
  • Understanding of cloud security at the infrastructure level 
  • Ability to design, operate, and troubleshoot cloud systems
  • AZ-104 (Azure Administrator) – required or willingness to obtain

Ability to obtain a 6C Public Trust clearance is required. An initial onsite presence is expected, with hybrid flexibility thereafter.
Technologies: Microsoft Azure (IaaS: VMs, VNETs, NSGs, VPN, Load Balancer), Azure Storage & Backup, Azure Monitor, Defender for Cloud, Terraform/Bicep/ARM, Azure DevOps, AKS, PowerShell/Python/Bash, Windows/Linux administration, Active Directory, DNS/DHCP, GPO, Intune, and M365 ecosystem tools.
