About The Position

The client is seeking a hands-on Field Network Engineer to serve as a senior technical resource within the Intelligent Transportation Systems (ITS) program. The role is responsible for designing, deploying, and operating a secure, highly available ITS network connecting traffic signals, video surveillance systems, and IoT devices across the District of Columbia. The network uses Metro Ethernet as its transport underlay and a Cisco DMVPN secure overlay to connect distributed field sites to client headend facilities and data centers. Work takes place in field and datacenter environments, with a focus on uptime, safety, and reliability in mission-critical operations. The engineer will deploy and support Cisco DMVPN networks, configure and troubleshoot VPN and routing components, coordinate Metro Ethernet service provisioning, manage WAN redundancy, and perform field installations and cutovers. The role also includes maintaining network segmentation, QoS, end-to-end connectivity, and network documentation; supporting traffic signal, video surveillance, and IoT infrastructure; migrating remote aggregation points to DMVPN-based transport; and ensuring encrypted communications and compliance with security policies. This is a contract W-2/1099 position offering flexible work-from-home options. Compensation is $60.00–$65.00 per hour.
