Level 2 NOC Systems Administrator – Linux/Unix Focus
WFA Digital Insight
Unisys is looking for a Level‑2 NOC Systems Administrator who lives and works entirely online, yet will be responsible for the health of production‑grade Linux and Unix environments. What makes this posting stand out is the blend of hands‑on server work—re‑imaging, patching, package management—and a clear expectation to own tickets through root‑cause analysis, not merely to forward them. The role also emphasizes knowledge transfer: creating runbooks and training Level‑1 analysts, which signals that Unisys values documentation and internal mentorship. Candidates should be comfortable with 24×7 shift rotation and be ready to document compliance, licensing, and configuration data with the same rigor they apply to daily monitoring.

How to Stand Out
- Highlight specific Linux package‑manager commands you’ve used (yum, apt, rpm) in your résumé and during interviews.
- Prepare a short runbook example that shows how you document a common troubleshooting flow.
- Emphasize any experience with 24/7 shift work; mention how you manage hand‑overs and on‑call fatigue.
- If you have RHCE/RHCSA or similar certifications, place them prominently on your profile.
- During technical screens, be ready to walk through a recent incident from detection to root‑cause analysis.
- Ask interviewers about the monitoring tools they rely on; aligning your knowledge with their stack shows preparation.
- Verify export‑control eligibility early to avoid later disqualification.
