As a highly skilled Linux Subject Matter Expert (SME), you will be responsible for managing and optimizing Linux-based systems such as Ubuntu, SUSE, and Red Hat, along with a proficient command of AWS services. Your role will involve designing, implementing, and supporting secure and scalable Linux environments, both on-premises and in the cloud. You will be expected to manage and maintain Linux systems across different distributions, including Ubuntu, SUSE, and Red Hat Enterprise Linux (RHEL). Additionally, deploying, configuring, and monitoring AWS cloud infrastructure while adhering to best practices for security, scalability, and performance will be crucial aspects of your responsibilities. Automation of routine system administration tasks using scripting languages like Bash, Python, etc., will be essential. Ensuring high availability of Linux servers through the implementation of clustering, failover, and backup solutions is another key responsibility. Monitoring system performance, identifying bottlenecks, and optimizing Linux environments will also be part of your role.
