Full Job Description

Description:

The District Department of Transportation (DDOT) is seeking a hands-on Field Network Engineer to serve as a senior technical resource within the Intelligent Transportation Systems (ITS) program. This role is responsible for the design, deployment, and day-to-day operations of a secure, highly available ITS network connecting traffic signals, video surveillance systems, and IoT devices across the District of Columbia.

The network environment leverages Metro Ethernet services as the transport underlay and a Cisco DMVPN secure overlay to link distributed field sites back to DDOT’s headend facilities and data centers. The engineer will work in both field and datacenter environments, with a focus on uptime, safety, and reliability in mission-critical operations.

Key Responsibilities

DMVPN & Secure Overlay Networking

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.

Metro Ethernet & WAN Transport

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.

Network Engineering & Operations

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.

ITS Infrastructure Support

Support Dot’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.

Security & Compliance

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 Environment

Combination of field work (street-level cabinets, utility corridors), data center operations, and remote support.
Travel to field locations across the District required; valid driver’s license required.
Ability to lift and rack network equipment up to 50 lbs.
Participation in scheduled maintenance windows and on-call availability for after-hours emergency response.

Requirements: Bachelor’s degree in Computer Science, Information Technology, Network Engineering, or a related field (or equivalent professional experience)
