While both positions are vital to a modern tech organisation, Support Engineer and Systems Administrator have fundamentally different daily workflows.
Support Engineer focuses primarily on resolving technical product issues that go beyond scripted Tier 1 troubleshooting, reproducing bugs, and working with engineering teams to fix or work around them. Day-to-day work revolves around diagnosing application, API, or infrastructure issues from customer tickets, writing reproduction steps and logs for engineering handoff, updating a knowledge base, and joining calls with technical customers to walk through fixes.
Systems Administrator focuses on managing, maintaining, and troubleshooting enterprise IT infrastructure across Windows Server, Linux, Active Directory, VMware virtualisation, and hybrid Azure cloud environments to ensure availability and performance. Their time is spent managing Windows Server and Linux server environments, administering Active Directory, Group Policy, and Azure Active Directory, performing routine patching, backup monitoring, and capacity management, troubleshooting hardware and software incidents escalated from the service desk, supporting VMware vSphere and Microsoft Hyper-V virtualisation, configuring DNS, DHCP, and SMTP network services, and contributing to change advisory board processes.
