6yrs Field Network Engineer with Intelligent Transportation Systems

GoIntellects Inc.•Washington, DC

3d•$61 - $65•Hybrid

About The Position

The Field Network Engineer supports and maintains network infrastructure for Intelligent Transportation Systems (ITS) for the DC Government in Washington, DC. The role deploys and supports Cisco DMVPN hub-and-spoke and spoke-to-spoke overlay networks over Metro Ethernet, configures and troubleshoots IPsec VPN profiles, GRE tunnels, NHRP mappings, and tunnel interfaces, and implements dynamic routing for failover and path selection. It also develops redundancy strategies, including LTE/5G backup paths, and monitors tunnel health, latency, throughput, and service levels. The engineer coordinates Metro Ethernet circuit provisioning and incident resolution with service providers; manages dual-WAN redundancy and carrier handoffs; and performs field installations and cutovers of network equipment. Responsibilities include managing VLANs, IP addressing, Layer 2/Layer 3 connectivity, network segmentation, and QoS, as well as troubleshooting end-to-end connectivity and maintaining network documentation. The position ensures reliable, low-latency transport connectivity for traffic signal control systems, CCTV/video surveillance platforms, and IoT field devices. It supports cabinet upgrades and migrations from legacy infrastructure to DMVPN-based transport. The engineer also applies encryption and security policies, manages VPN certificates and key rotation, implements IoT security practices, and supports audits, vulnerability assessments, and remediation. The work combines field assignments at street-level cabinets and utility corridors, data center operations, and remote support. Travel to field locations across the District is required. The role requires a valid driver’s license, the ability to lift and rack equipment weighing up to 50 pounds, participation in scheduled maintenance windows, and on-call availability for after-hours emergency response.

Availability for on-call after-hours emergency response.

Responsibilities

Deploy and support Cisco DMVPN Phase 2 and Phase 3 hub-and-spoke and spoke-to-spoke overlay networks across Metro Ethernet transport.
Configure and troubleshoot IPsec VPN profiles, GRE tunnels, NHRP mappings, and tunnel interfaces.
Implement BGP, OSPF, and EIGRP over DMVPN tunnels to support automated failover and optimal path selection.
Design failover and redundancy strategies, including LTE/5G backup paths.
Monitor VPN tunnel health, latency, throughput, network availability, and service-level compliance.
Coordinate Metro Ethernet circuit provisioning, turn-up, and incident resolution with service providers.
Manage dual-WAN redundancy models and carrier handoff configurations at each site.
Perform field installations and cutovers of routers, switches, cabinets, and handoff equipment.
Manage VLAN configurations, IP addressing, and Layer 2/Layer 3 connectivity between remote aggregation points and headend data centers.
Implement and maintain network segmentation using VRFs, VLANs, and firewall policies.
Apply and tune QoS policies to prioritize latency-sensitive traffic such as signal control and video.
Troubleshoot network issues end-to-end from field sites through WAN transport to the data center.
Maintain network diagrams, IP assignments, equipment inventories, and configuration records.
Provide reliable, low-latency transport connectivity for traffic signal control systems, CCTV/video surveillance platforms, and IoT field devices.
Coordinate field cabinet upgrades to accommodate network equipment, including power and environmental requirements.
Manage migration of remote aggregation points from legacy infrastructure to DMVPN-based transport.
Ensure network connections use encrypted communications in accordance with DDOT and District government security policies.
Manage VPN certificate lifecycles, key rotation, and trust domain configurations.
Implement IoT security and segmentation best practices for field-deployed devices.
Support security audits, vulnerability assessments, and remediation efforts on ITS network infrastructure.
Travel to field locations across the District and participate in scheduled maintenance windows and after-hours emergency response.
