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.
