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.
The organization is seeking a technical leader first and foremost. While formal people management is not initially required, the right individual will have the opportunity to mentor team members, influence strategy, and potentially grow into a permanent leadership position.
What You'll Do
Support and maintain a large-scale network infrastructure supporting operational technology systems, surveillance devices, and field communications equipment
Troubleshoot complex Layer 2 and Layer 3 networking issues across wired and wireless environments
Manage network segmentation, VLANs, routing, switching, and connectivity across distributed locations
Participate in ongoing network modernization and future-state architecture initiatives
Work closely with engineering teams, external vendors, and stakeholders on infrastructure improvement projects
Review and contribute to network design documentation, diagrams, and technical standards
Evaluate vendor recommendations and provide technical guidance during future network redesign efforts
Mentor junior technical staff and serve as a trusted technical resource for the team
Present technical updates and recommendations to leadership and executive stakeholders in an easy-to-understand format
Perform both office-based and field-based troubleshooting activities throughout the metro area
Required Qualifications
5+ years of hands-on network engineering experience
Strong expertise in:
Layer 2 and Layer 3 networking
Routing and switching
VLAN design and implementation
Network segmentation
Troubleshooting complex network environments
Experience supporting both wired and wireless network infrastructures
Ability to create and maintain network diagrams and technical documentation
Strong communication skills with the ability to explain technical concepts to non-technical audiences
Valid driver's license and ability to travel locally throughout the region for field support activities
Must be authorized to work in the United States without current or future sponsorship requirements
Preferred Qualifications
Experience with Juniper networking technologies
Experience with Ruggedcom or other industrial networking equipment
Cisco networking experience
Wireless mesh networking experience
Wi-Fi design, deployment, and troubleshooting experience
Experience evaluating vendor proposals and participating in infrastructure planning initiatives
Familiarity with operational technology (OT), intelligent transportation systems (ITS), surveillance networks, or other critical infrastructure environments
What We're Looking For
The ideal candidate is a true hands-on engineer who enjoys getting into the details of network operations and architecture. This is not a position for someone who has moved away from technology and into pure management.
We're seeking an individual who can:
Troubleshoot complex issues independently
Think strategically about future network architecture
Communicate effectively with technical and non-technical stakeholders
Lead through influence rather than formal authority
Thrive in both office and field environments
Why This Opportunity?
Support one of the largest public infrastructure networks in the region
Direct influence on an upcoming large-scale network modernization initiative
Mix of operational support and strategic architecture work
Opportunity to work with wireless, fiber, and industrial networking technologies
High visibility with leadership and decision-makers
Clear path toward future leadership opportunities for the right individual
Meaningful work that directly impacts the daily lives of thousands of residents and commuters
If you're a senior network engineer looking for a role where your technical expertise will have a measurable impact on critical city-scale infrastructure, we'd love to hear from you.
