Systems Limited; Islamabad; On-site; PKR 2,000,000 - 4,500,000; Full time

Job summary

Systems Limited seeks a highly experienced Linux Engineer to design, standardize, automate, and optimize enterprise-wide Linux platforms. This hands-on role focuses on building reusable solutions for Linux Operations and Infrastructure teams, rather than routine administration.

The position covers creating OS/container images, provisioning automation, and security hardening, with exposure to OpenShift, VMware, Kubernetes, and cloud environments. A senior level with RHCE is required.

Qualifications

• Bachelor’s degree in Computer Science, IT, Engineering, or a related field, or equivalent experience.
• 12+ years of experience in Enterprise Linux, including Senior Linux Administration and Linux Engineering.
• Strong hands-on experience with RHEL 6 onwards.
• Experience with Red Hat Satellite Server (Kickstart preferred).
• Proficiency in PXE, DHCP, Redfish, and automated OS provisioning.
• Ability to create standardized OS/container images across on-premises, VMware, OpenShift, and cloud environments.
• Strong OpenShift expertise and Kubernetes in cloud environments.
• Proficiency with Ansible, Bash, Python, Packer, and CI/CD/DevOps.
• Solid knowledge of DNS, NFS, NTP, SNMP, SMTP, Active Directory, TCP/IP, Ethernet.
• Linux troubleshooting, kernel analysis, performance tuning, and optimization.
• Experience with enterprise monitoring, logging, and SIEM.
• Strong Linux security hardening and configuration management.
• RHCE certification required; RHCA a plus.
• AWS/Azure certifications are advantageous.

Responsibilities

• Design and maintain enterprise-wide Linux platform standards and automated build solutions.
• Develop standardized OS and container golden images for bare-metal, VMware, OpenShift, and cloud environments.
• Manage and enhance Red Hat Satellite, Kickstart, PXE, DHCP, and Redfish for automated provisioning.
• Engineer and optimize RHEL platforms, including kernel, CPU, memory, I/O, and network performance.
• Define and implement Linux security, hardening, configuration, and compliance standards.
• Develop monitoring and observability solutions for Linux OS and server infrastructure, integrating with Splunk, ELK, SIEM, and AppDynamics.
• Automate patching, firmware updates, configuration management, monitoring, and compliance using Ansible, Bash, and Python.
• Develop AI-driven solutions to improve Linux engineering and BAU operations.
• Support Linux platforms across OpenShift, VMware, Kubernetes, and cloud environments.
• Act as a Level 3 escalation point for critical incidents and lead root cause analysis.
• Collaborate with Infrastructure, DevOps, Security, EA, and BAU teams to establish future-state Linux standards.
• Work with technology vendors and service partners to drive platform improvements and roadmap initiatives.
• Participate in a 24x7 on-call rotation for critical incidents.

• Develop standardized OS and container golden images for bare-metal, VMware, OpenShift, and cloud environments.
• Manage and enhance Red Hat Satellite, Kickstart, PXE, DHCP, and Redfish for automated provisioning.
• Engineer and optimize RHEL platforms, including kernel, CPU, memory, I/O, and network/TCP performance.
• Define and implement Linux security, hardening, configuration, and compliance standards.
• Develop monitoring and observability solutions for Linux OS and Dell/HPE server infrastructure, integrating with Splunk, ELK, SIEM, and AppDynamics.
• Automate patching, firmware updates, configuration management, monitoring, and compliance using Ansible, Bash, and Python.
• Develop AI-driven solutions to improve Linux engineering and BAU operations.
• Support Linux platforms across OpenShift, VMware, Kubernetes, and cloud environments.
• Act as a Level 3 escalation point for critical incidents and lead root cause analysis.
• Collaborate with Infrastructure, DevOps, Security, Enterprise Architecture, and BAU teams to establish future-state Linux standards.
• Work with technology vendors and service partners to drive platform improvements and roadmap initiatives.
• Participate in a 24x7 on-call rotation for critical incidents.

Requirements

• Bachelor’s degree in Computer Science, IT, Engineering, or a related field, or equivalent experience.
• 12+ years of experience in Enterprise Linux, including at least 5 years in Senior Linux Administration and 5 years in Linux Engineering.
• Strong hands-on expertise with RHEL 6 onwards.
• Extensive experience with Red Hat Satellite Server, preferably Kickstart.
• Strong knowledge of PXE, DHCP, Redfish, and automated OS provisioning.
• Hands-on experience creating standardized OS/container images across on-premises, VMware, OpenShift, and cloud environments.
• Strong expertise in Red Hat OpenShift and experience with Kubernetes in cloud environments.
• Proficiency in Ansible, Bash, Python, Packer, and CI/CD/DevOps technologies.
• Strong understanding of DNS, NFS, NTP, SNMP, SMTP, Active Directory, TCP/IP, and Ethernet.
• Strong Linux troubleshooting, kernel analysis, performance tuning, and optimization skills.
