Network Engineer – NMS and Automation (w/ active Secret)

We need to output HTML fragment with sections: About the role? The posting includes Job Description, Primary Roles And Responsibilities, Basic Qualifications, etc. We need to use

for section headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We must only include sections when posting has real specific content. We have Salary range info, Benefits snapshot. No explicit schedule beyond full-time onsite. Could include Schedule? The posting says Full-time, Onsite. That's schedule info. So we can include Schedule section with that. Pay section with salary range. Benefits section with snapshot. Responsibilities section with primary roles and responsibilities. Requirements/Qualifications: Basic Qualifications includes education, clearance, etc. Could separate Requirements (clearance, education) and Qualifications (skills). But we can combine? The instruction: Use headings for those categories. We need to decide what content goes where. Likely: About the role (brief description), Responsibilities (primary roles), Requirements (clearance, education, citizenship), Qualifications (OS specialization, core Linux skills, protocols, automation, etc.), Skills (maybe technical skills like network engineering, security, etc.), Benefits, Pay, Schedule. We must not repeat job title. Must not include boilerplate like EEO, legal, etc. Must preserve all substantive info. We need to avoid filler like "commensurate with experience". Not present. We need to output only HTML fragment, no /, no markdown fences. Let's extract content. Job Description paragraph: "Critical Solutions is seeking a Network Engineer - Network Management Systems (NMS) and Automation to support our federal customer. The NMS team member must possess expert command of the monitoring ecosystem, leveraging specific tools to deliver core organizational advantages:" Then list of functional domain tool mechanics etc. That's part of description. Could be About the role. Primary Roles And Responsibilities: list of items under RHEL 8 Back-End Operations & System Administration and NMS Application & Tool Support. We'll capture those as bullet list. Basic Qualifications: Active Secret clearance, Education: Bachelor's degree..., OS Specialization..., Core Linux Skills..., Protocols..., Automation... Then there is a block "Core Technical Skills" with many subcategories: Network Engineering, Network Security, Infrastructure Administration, Automation & DevOps, Network Management Systems (NMS) & Operations, Analytical & Leadership Skills, Collaboration & Communication. Those could be Qualifications or Skills. We need to decide mapping. Simplify: Use sections: - About the role: combine Job Description paragraph and maybe the functional domain tool mechanics list? Could be a

with description and then a

for the bullet list of functional domain tool mechanics. - Responsibilities: Primary Roles And Responsibilities content. - Requirements: Basic Qualifications (clearance, education, citizenship maybe). Also mention US citizenship required. - Qualifications: OS Specialization, Core Linux Skills, Protocols, Automation (maybe combine as qualifications). Or we could put those under Qualifications. - Skills: Core Technical Skills (Network Engineering, Network Security, Infrastructure Administration, Automation & DevOps, NMS & Operations, Analytical & Leadership Skills, Collaboration & Communication). Could be a list. - Benefits: Benefit Snapshot. - Pay: Salary range. - Schedule: Full-time, Onsite (maybe also mention locations Norfolk, VA, Jacksonville, FL, Pearl Harbor). Could include location info? Not a heading but could be in About the role? But schedule section: we can put "Full-time, Onsite. Primary location Norfolk, VA; also Jacksonville, FL or Pearl Harbor." We must not repeat job title. Must not include Job ID etc. We must not include duplicated lines. Ensure we preserve all substantive info. Let's extract details. Job Description paragraph: "Critical Solutions is seeking a Network Engineer - Network Management Systems (NMS) and Automation to support our federal customer. The NMS team member must possess expert command of the monitoring ecosystem, leveraging specific tools to deliver core organizational advantages:" Then list: 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. We need to preserve all that. Could format as
• each line. Primary Roles And Responsibilities: Under headings: 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. 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.

We need to remove boilerplate like "The salary range for this position represent the typical salary range for this job level and this does not guarantee a specific salary." That's still substantive? It's explanatory but maybe we can keep? The instruction: Preserve ALL substantive information; do NOT invent or summarize away detail. So we should keep that sentence as it's part of the posting. However it's somewhat generic but still part of posting. We'll keep. Similarly for benefits snapshot we keep. Now we need to output HTML with sections. We'll decide:
