Summary: HRUCKUS is looking for an experienced Senior Field Network Engineer to serve as a senior technical resource within the Intelligent Transportation Systems (ITS) program, designing, deploying, and operating a secure, highly available ITS network connecting traffic signals, video surveillance systems, and IoT devices.

Position Description: This role is responsible for the deployment and day-to-day operations of a secure ITS network across the District of Columbia. Leveraging Metro Ethernet services and Cisco DMVPN secure overlays, the engineer will work in both field and datacenter environments with a strong focus on uptime, safety, and reliability in mission-critical operations.

Position Responsibilities:

• Deploy and support Cisco DMVPN (Phase 2/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 for the DMVPN fabric.
• Implement dynamic routing protocols (BGP, OSPF, EIGRP) over DMVPN tunnels to support automated failover and optimal path selection.
• Design failover and redundancy strategies, including LTE/5G backup paths, to ensure uninterrupted connectivity during circuit or equipment outages.
• Monitor tunnel health, latency, and throughput to maintain performance standards across all VPN connections.
• Coordinate with service providers on Metro Ethernet circuit provisioning (E-Line, E-LAN), turn-up, and incident resolution.
• 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 schemes, 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 to isolate ITS traffic domains.
• Apply and tune QoS policies to prioritize latency-sensitive traffic such as signal control and video.
• Troubleshoot network issues end-to-end from field site through WAN transport to data center.
• Maintain accurate network documentation including diagrams, IP assignments, equipment inventories, and configuration records.
• Support DDOT’s traffic signal control systems, CCTV/video surveillance platforms, and IoT field devices by ensuring reliable, low-latency transport connectivity.
• Coordinate field cabinet upgrades to accommodate new network equipment, including power and environmental requirements.
• Manage the migration of remote aggregation points from legacy infrastructure to modern DMVPN-based transport.
• Monitor network performance, availability, and service-level compliance across all ITS transport links.
• Ensure all network connections utilize encrypted communications per 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.
• Work in a combination of field settings (street-level cabinets, utility corridors), data center operations, and remote support.
• Travel to field locations across the District (valid driver’s license required).
• Lift and rack network equipment up to 50 lbs.
• Participate in scheduled maintenance windows and on-call availability for after-hours emergency response. xhqgsiq
