RHEL 8 Back-End Operations & System Administration Operating System (OS) Lifecycle Management: Provision, configure, and maintain RHEL 8 servers hosting the core NMS applications across physical, virtual, and air-gapped environments. Kernel & Performance Tuning: Optimize Linux kernel parameters, memory allocation, and storage subsystems to handle massive telemetry and configuration data intake (SNMP, NetFlow, Syslog, SSH, SCP) without data loss. Patching & Vulnerability Mitigation: Leverage Red Hat Satellite or custom repositories to manage package rollouts, applying routine security errata and OS updates. Automation & IaC: Write and maintain Ansible playbooks and other language scripts to automate server provisioning, user management, and repetitive operational tasks related to NMS tool objects. Security & Compliance: Enforce security Linux policies, access rules, and STIG compliance to ensure the monitoring platform resists compromise. Storage & File System Management: Configure and expand LVM (Logical Volume Manager) structures to manage high-write NMS databases and syslog partition scaling.2. NMS Application & Tool Support Platform Administration: Deploy, upgrade, and troubleshoot enterprise-grade NMS applications (Open Text NNMi, Open Text Network Automation, Cisco Catalyst Center, Arista Cloud Vision, Aruba Airwave and others). Data Integration: Architect and maintain integrations between NMS engines, CMDB asset databases, and ITSM platforms like ServiceNow via APIs. Polling & Telemetry Management: Configure polling intervals, customize SNMP MIBs and traps, and set up NetFlow collectors to build clear network matrices. Fault Isolation & Alerting: Construct alerting logic, thresholds, and notification profiles to minimize alert fatigue while ensuring critical outages surface instantly.Core Tool Functionality & Strategic Benefits The NMS team member must possess expert command of the monitoring ecosystem, leveraging specific tools to deliver core organizational advantages: Functional Domain Tool Mechanics / Features Business & Operational Benefits Fault & Performance Monitoring Continuous SNMP/ICMP polling Real-time alerting mechanisms Synthetics & packet analysis Minimizes MTTR: Faster root-cause isolation lowers Mean Time to Resolution. Reduces Downtime: High-availability metrics prevent outages before they cascade. Configuration & Change Control Automated backups of device configs Real-time configuration drift detection Mass configuration deployments Ensures Compliance: Restores safe baseline settings rapidly during bad changes. Secures Network: Flashes alerts on unauthorized or rogue configuration alterations. Traffic Analytics & Planning NetFlow / sFlow / IPFIX collection Historical data trending charts Dynamic topology mapping Cost Optimization: Validates bandwidth usage patterns for smarter capacity planning. Uncovers Bottlenecks: pinpoints bandwidth hogs and abnormal traffic spikes.Required Qualifications & Technical Competencies Active secret clearance Education: Bachelor's degree in computer science, IT, Network Engineering, or an equivalent technical field.

Experience: 3-5+ years of dedicated experience managing enterprise networks and network management platforms. OS Specialization: Hands-on experience administering RHEL 8 environments (RHCSA or RHCE certifications preferred). Core Linux Skills: Advanced knowledge of systemd, system logging (rsyslog, journald), and native RHEL troubleshooting utilities (top, iotop, netstat, tcpdump). Protocols: Deep knowledge of networking protocols including SNMP (v3), Syslog, SSH, ICMP, NetFlow, and TACACS+/RADIUS. Automation: Proficiency in Ansible and scripting languages (Python, Bash) to run configuration infrastructure as code.
