The role includes platform engineering, performance optimization, operating system lifecycle management, security hardening, automation, capacity planning, major incident support, root cause analysis, and technical governance. The ideal candidate should possess deep expertise in Red Hat Enterprise Linux, Oracle Linux, SUSE Linux Enterprise Server, Ubuntu, IBM AIX, and/or Oracle Solaris, depending on the platform landscape. Strong experience with Shell scripting, Python, Ansible, VMware, Microsoft Azure, AWS, clustering, high availability, and enterprise infrastructure operations is required. The role will work closely with infrastructure architects, cloud engineering, cybersecurity, application, database, network, storage, backup, and service management teams to ensure that Linux/Unix platforms remain secure, scalable, resilient, and operationally efficient. Key Responsibilities Linux/Unix Platform Engineering Design, engineer, implement, and support enterprise Linux/Unix platforms across physical, virtual, private-cloud, and public-cloud environments. Define standard operating system builds, configurations, security baselines, and engineering patterns. Perform complex server provisioning, configuration, migration, upgrade, consolidation, and decommissioning activities. Evaluate platform requirements and recommend appropriate operating system, compute, storage, availability, and connectivity configurations. Provide engineering support for new applications, infrastructure transformations, and platform modernization initiatives. 2. Advanced Linux/Unix Administration Provide expert-level administration of Linux distributions such as RHEL, Oracle Linux, Ubuntu, and SLES. Support Unix platforms such as IBM AIX and Oracle Solaris, where applicable. Administer and troubleshoot kernel parameters, system services, boot processes, package repositories, authentication, SSH, sudo, cron, logging, and operating system configurations.

Lead troubleshooting across operating system, virtualization, storage, network, database, cloud, and application layers. Analyze system logs, crash dumps, diagnostic outputs, performance data, and platform configurations to identify technical causes.
