- Six years preparing complex technical documentation.
- Six years of ITS experience, including traffic signal controllers, CCTV/video surveillance transport, and traffic management.
- Six years of experience with LTE/5G failover solutions.
- Six years of network automation experience using Ansible or Python-based scripting.
- Five years of knowledge of IoT security and segmentation best practices.
- Eight years of knowledge of high-availability network design, redundant architectures, and disaster recovery planning.
- Six years of fiber optic network experience, including single-mode fiber design and SFP/SFP+ transceivers.
- Six years of prior experience working with a state or municipal Department of Transportation.
- Active CCNA certification.
Nice To Haves

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 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, for connectivity during circuit or equipment outages.
- Monitor tunnel health, latency, and throughput across VPN connections.
- Coordinate Metro Ethernet circuit provisioning (E-Line, E-LAN), 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 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 sites through WAN transport to data centers.
- Maintain network diagrams, IP assignments, equipment inventories, and configuration records.
- Support 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 network equipment, including power and environmental requirements.
- Manage migration of remote aggregation points from legacy infrastructure to modern DMVPN-based transport.
- Monitor network performance, availability, and service-level compliance across ITS transport links.
- Ensure network connections use encrypted communications consistent 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.
