The posting

As a Junior Red Hat Linux Systems Engineer, you will execute essential day-to-day RHEL operational activities, platform maintenance, and deployment tasks under the guidance of the Senior Systems Engineer. This hands-on role focuses on executing patching and hardening procedures, post-upgrade validation, automation testing, and providing critical standby support during scheduled maintenance windows.

Key Responsibilities

  • Provide onsite and remote standby support for RHEL patching and hardening cycles across SIT, UAT, DR, and Production environments (including night and weekend maintenance sessions).
  • Perform pre-patch health checks, backup verifications, package updates, post-change service validation, and formal audit evidence capture.
  • Execute and test approved automation scripts/playbooks for server provisioning, in-place upgrades (IPUG), and CIS hardening; log and escalate execution failures promptly.
  • Assist with golden image maintenance, security agent installations, configuration verification, and technical documentation updates.
  • Research assigned security alerts, map affected packages/versions against the active RHEL estate, document findings, and complete assigned remediation tasks.
  • Maintain precise service request, incident, change, and inventory records. Promptly escalate technical risks, failed pre-checks, or procedure deviations to the Senior Engineer.

Required Qualifications & Experience

  • Diploma in Computer Science, Information Technology, Engineering, or a related discipline.
  • 2–4 years of experience in Linux systems administration or IT infrastructure operations.
  • Solid foundational knowledge of RHEL 7/8/9 administration, including user/group management, permissions, yum/dnf package management, services, LVM, and basic networking.
  • Basic scripting capabilities using Bash, Python, or Ansible.
  • Understanding of patching practices, vulnerability remediation, OS hardening concepts, and formal change-management processes.
  • RHCSA preferred, or a commitment to obtain certification within an agreed timeframe post-hire.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
