Employment type: Contract w2/1099/C2C

Complete Description:

The client 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 client 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.

Duties & 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.

Skills:

· Bachelor’s degree in Computer Science, Information Technology, Network Engineering, or a related field (or equivalent professional experience). Required 11 Years

· Conveying technical and functional concepts for a specific technical specialty. Required 6 Years

· Preparing complex technical documentation. Required 6 Years

· Experience with Intelligent Transportation Systems (ITS) including traffic signal controllers, CCTV/video surveillance transport, and traffic management. Required 6 Years

· Experience with LTE/5G failover solutions. Required 6 Years

· Network automation skills using Ansible or Python-based scripting. Required 6 Years

· Knowledge of IoT security and segmentation best practices. Required 5 Years

· Knowledge of high-availability network design, redundant architectures, and disaster recovery planning. Required 8 years

· Fiber optic network experience — including single-mode fiber design, SFP/SFP+ transceivers. Required 6 Years

· Prior experience working with a state or municipal Department of Transportation. Required 6 Years

· Active CCNA Certification. Required

· CCIE Enterprise Infrastructure, Certified Fiber Optic Technician (CFOT) or equivalent, • CompTIA Network+ or Security+ ITIL v4 Foundation. Highly desired
