• Strong understanding of networking fundamentals (TCP/IP, DNS, SSH, firewall concepts).
• Knowledge of storage technologies (NAS, SAN, distributed/parallel file systems – basic awareness).
• Scripting and automation using Bash/Shell and/or Python.
• Familiarity with monitoring and logging tools (e.g., Nagios, Zabbix, Prometheus, Grafana, ELK Stack).
• Strong troubleshooting, analytical thinking, and incident resolution skills.

Responsibilities

• Support day-to-day operations of HPC clusters, including compute nodes, storage systems, and high-speed networking infrastructure.
• Monitor system performance, workload execution, job scheduling, and resource utilization across distributed environments.
• Perform installation, configuration, patching, and maintenance of Linux/Unix operating systems (RHEL, CentOS, Ubuntu).
• Administer physical and virtualized server environments (x86 architecture, VMware/KVM).
• Support workload management systems and job schedulers (Slurm, PBS, LSF) for batch processing and resource allocation.
• Conduct system health checks, log analysis, troubleshooting, and incident management (root cause analysis).
• Manage user accounts, access control, and authentication systems (LDAP, Active Directory integration).
• Assist in provisioning and configuration of HPC environments, including software stack deployment and environment modules.
• Collaborate with senior engineers on cluster optimization, scaling, and performance tuning initiatives.
• Maintain system documentation, operational procedures, and runbooks
