About The Position

The Network Engineer II provides Tier 3 engineering and operational support for the Indian Health Service (IHS) enterprise network as part of a 24x7 Network Operations & Support Center (NOSC). This role is responsible for maintaining reliable, secure, and compliant network services across a large WAN and multiple data centers, supporting hundreds of geographically distributed sites. The engineer troubleshoots complex incidents, performs configuration changes and upgrades, coordinates with telecommunications and hardware vendors, and produces required documentation and reporting in accordance with ITIL processes and Federal security standards. Routing & Switching (R&S) Provide support for routing, switching, and WAN connectivity incidents; diagnose and remediate degraded performance and outages. Configure, maintain, and troubleshoot Cisco Nexus/IOS-based routing and switching platforms in enterprise environments located in data centers and individual IHS facilities. Implement and support standard routing protocols OSPF, BGP. Perform software upgrades and patching, maintaining secure configuration baselines and standardized templates. Support QoS policies for voice/video and critical clinical applications; validate traffic behavior using flow and packet analysis tools as needed. Network Monitoring & Event Management Monitor network infrastructure for circuit, device, and security events; detect both hard failures and degraded performance. Respond to alerts and incidents with urgency and ownership; communicate status to stakeholders and impacted sites. Use monitoring and analysis tools such as Splunk, PRTG, LiveAction NX, Cisco Catalyst Center, SNMP/NetFlow, and log review to isolate root cause. Generate operational reporting (e.g., daily situational awareness, weekly summaries, monthly network availability and status reports) as required by the program. Wireless Support enterprise wireless LAN environments (Cisco and Aruba) including controllers and access point configurations. Troubleshoot wireless performance, authentication, and connectivity issues; coordinate changes and maintenance activities remotely. Security & Compliance Support Federal communication standards and security requirements; address vulnerabilities and compliance findings in coordination with security stakeholders. Implement and maintain firewall and VPN configurations as assigned, including IPsec tunnel support and rule change implementation per policy. Perform log review and analysis to help identify potential threats; support incident response investigations when requested. Operate in accordance with DISA STIG’s, NIST SP 800-53 controls, FISMA expectations, FIPS 140-2 encryption requirements, and CDM support activities. Telecommunications & Circuit Management Provide support for circuit incident management through close coordination with Verizon and other telecom providers. Initiate and manage vendor tickets; coordinate circuit installations/changes, activations, and acceptance testing. Maintain circuit inventory and external connections information; support capacity monitoring and planning activities. Support Telecommunications Service Priority (TSP) circuit registration processes when directed. Configuration, Change, Incident & Problem Management Implement configuration changes on network devices (routers, switches, firewalls, wireless controllers) following approved change control processes. Log and track incidents, requests, and changes in ServiceNow; ensure documentation is complete, accurate, and timely. Participate in root-cause analysis, problem management, and continuous improvement efforts; identify opportunities for automation and standardization. Design, Implementation & Modernization Support Support network architecture/design, installation, implementation, maintenance, and troubleshooting of core communications infrastructure. Develop and maintain reference designs, implementation/test plans, and site topology documentation. Support new technology deployments (e.g., SD-WAN, cloud connectivity) including proof-of-concept testing and operationalization. Support connections to external environments (e.g., Azure/AWS) and maintain compliance expectations (e.g., TIC where applicable). Process & Documentation Develop and maintain SOPs for monitoring alerts, escalation, and stakeholder notifications. Maintain accurate network diagrams (physical and logical) and update documentation within 2 business days of topology changes. Maintain equipment and IP address/inventory documentation; track external connections and allocations as required. Tools & Technologies (Representative) Routing/Switching: Cisco Nexus, Catalyst (e.g., C9300), IOS/IOS-XE platforms WAN: MPLS/Internet, site-to-site VPN, DMVPN/Cisco SD-WAN Security: Palo Alto (Panorama), Cisco Firepower Management Center, Cisco ISE; Splunk Monitoring/Visibility: PRTG, LiveAction NX, Catalyst Center, NetFlow/SNMP, Wireshark NAC/Asset Visibility: ForeScout; traffic distribution/visibility in supported environments ITSM/Workflow: ServiceNow (incidents, requests, changes, problem records) Performance Expectations Support the team in a 24x7 operational support requirement which may include some Federal holiday coverage and after-hours work as needed (Compensation included). Meet or support program service targets (e.g., timely response to failures/alerts, timely communications, and required reporting deliverables). Maintain a high standard of customer communication, ownership, and follow-through; ensure issues are tracked to resolution or proper escalation. Follow approved maintenance windows for upgrades, particularly for 24-hour facilities; minimize service disruption and validate outcomes. Requirements Ability to obtain and maintain a U.S. Government Public Trust clearance (minimum Level 5C). 5+ years of enterprise network experience supporting large WAN infrastructures and/or data center networks. Hands-on experience with Cisco routing and switching; demonstrated ability to troubleshoot complex network communications and interoperability issues. Working knowledge of routing protocols (OSPF, BGP) and VPN technologies (IPsec). Experience using troubleshooting tools and methodologies (protocol analysis, log review, event correlation) and documenting findings clearly. Strong communication skills, sense of urgency, and a customer-focused mindset; ability to work independently and within a 24x7 operations team. Certifications CCNA required; CCNP or equivalent strongly preferred.
