Make a City-Wide Impact We're partnering with one of the largest municipal transportation organizations in the Southwest to identify a Senior Network Engineer who will play a critical role in supporting and modernizing a large-scale operational technology network that powers critical public infrastructure. This is a highly visible opportunity for a hands-on network engineer who enjoys solving complex connectivity challenges, working in the field, and helping shape the future design of a mission-critical network environment spanning more than 1,300 connected locations across a major metropolitan region.
