• 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.
• Experience with enterprise monitoring, logging, and SIEM solutions.
• Strong understanding of Linux security hardening and configuration management.
• RHCE certification required; RHCA is a plus.
• AWS/Azure certifications are advantageous.
