  • 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

  • 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.
