System Administrator I - III
About The Position
The System Administrator career track (Levels I through III) supports the design, deployment, and ongoing maintenance of client server and storage environments. Each level builds upon the last, with increasing expectations for technical depth, independence, automation capability, and leadership contribution. System Administrator I is an entry-level position designed for individuals with a foundation in IT who are ready to grow into infrastructure support. At this level, the focus is on learning the environment, performing routine maintenance, following documented procedures, and building core skills in Windows Server administration and ticketing. System Administrator II is a mid-level position for technicians who have demonstrated proficiency in daily system operations and are beginning to take greater ownership of their workload. At this level, the expectation is stronger technical depth, more independent troubleshooting, and active contribution to documentation and process improvement. System Administrator III is a senior-level position for experienced administrators who take ownership of complex environments, lead system implementations, and serve as escalation points for the team. At this level, the expectation is proficiency in virtualization, scripting, proactive maintenance, and mentoring junior staff. All levels participate in after-hours and on-call support rotations and work primarily through the company’s ticketing system to track time, document work, and manage client communications. All levels will be required to work onsite M-F.
