Junior Systems Administrator Resume Example

Overview

Systems administrator roles are the backbone of IT infrastructure, and companies need reliable people who can keep servers running, manage user accounts, and respond to issues quickly. For graduates, the key is showing you have already handled these responsibilities in a real environment, not just a university lab.

This resume belongs to Ryan Gallagher, a Computer Networks graduate from Ulster University. He completed a placement at a managed services provider supporting 25 client environments and holds CompTIA A+ and Network+ certifications. His resume works because it demonstrates operational reliability with specific uptime metrics and ticket resolution numbers.

What Makes This Resume Work

Uptime and ticket metrics prove reliability. Maintaining 99.5% uptime across 25 client environments and resolving 180+ tickets with a sub-15-minute response time are exactly the metrics that IT managers use to evaluate sysadmins. Ryan includes them prominently.

Active Directory experience is specific. Managing 800+ user accounts across 3 clients shows Ryan understands enterprise identity management. He names the specific tasks: provisioning, group policies, access controls. This tells a hiring manager he can handle day-to-day AD operations immediately.

Documentation is highlighted as a skill. Writing 10 runbook procedures demonstrates that Ryan does not just solve problems; he documents solutions so others can follow them. This is a highly valued trait in operations teams.

Key Takeaways

For sysadmin roles, your resume should emphasise reliability and operational metrics. Count the servers you managed, the tickets you resolved, and the uptime you maintained. CompTIA certifications (A+, Network+) are widely recognised entry credentials. If you wrote documentation, automated processes, or improved response times, make sure those details appear on your resume.
