Overview:

Kimley-Horn is seeking a Network Security Engineer to help lead and mature our network security function, with a primary focus on enterprise firewall architecture and operations.


This is a foundational role within our Information Security team, where you’ll take ownership of a growing firewall environment, influence security strategy, and help define the future of network security across a rapidly expanding, multi-site organization.

If you have a strong networking background and deep hands-on firewall experience—especially in Palo Alto environments—this is an opportunity to truly own and evolve a critical security domain.

 

This is not a remote position. Applicants must be legally authorized to work for Kimley-Horn in the U.S. without employer sponsorship. We do not typically sponsor H1-B or other work visa petitions.
Responsibilities:

Firewall Ownership & Network Security (Primary Focus)

  • Serve as the primary owner of Kimley-Horn’s enterprise firewall environment, including design, implementation, and ongoing optimization
  • Create, review, and maintain firewall policies and rules across on-prem and cloud environments
  • Lead firewall strategy decisions, including policy standardization, segmentation, and performance tuning
  • Administer and optimize Palo Alto firewalls and Panorama
  • Manage and enhance GlobalProtect policies and secure remote access configurations
  • Analyze and implement ACLs, rule bases, and logical security controls across a multi-vendor environment
  • Drive continuous improvement in firewall posture, balancing security and user experience

Cloud & Application Security

  • Support and manage Next-Gen Firewalls in Azure environments
  • Administer and optimize Web Application Firewalls (WAFs)
  • Participate in SASE and cloud security architecture discussions and reviews

Network Security Engineering & Operations

  • Implement and maintain network security controls, including firewalls, VPNs, IDS/IPS, and access controls
  • Troubleshoot complex networking and security issues across cloud and hybrid environments
  • Monitor and resolve network performance issues (latency, throughput, utilization, system slowness)
  • Partner with Network Operations and Cloud teams to review designs and provide a security-first perspective

Emerging Security Capabilities

  • Assist in evaluating and implementing Network Detection & Response (NDR) solutions
  • Support the transition and ongoing ownership of Cisco ISE capabilities
  • Contribute to security tooling decisions, standards, and long-term strategy

Collaboration & Leadership (Non-People Management)

  • Coordinate and guide work across matrixed IT partners
  • Provide technical guidance, training, and mentorship on network security best practices
  • Participate in incident response, change management, and after-hours maintenance for critical events
Qualifications:
  • Bachelor’s degree in Information Security, Cybersecurity, or a related field
  • 4+ years of experience in network security engineering or related roles within enterprise environments
  • Strong hands-on experience with firewall design, implementation, and management (required)
  • Direct experience with Palo Alto firewalls and Panorama
  • Experience with firewall architectures across internal, perimeter, and cloud environments
  • Experience administering Web Application Firewalls (WAFs)
  • Experience with Cisco ISE or similar identity-based network access platforms
  • Solid understanding of networking fundamentals (routing, switching, TCP/IP, DNS, DHCP)
  • Experience with change management practices and operational processes
  • Strong problem-solving skills and ability to perform under pressure
  • Excellent communication skills with the ability to explain technical concepts to non-technical stakeholders

Preferred Certifications:
Security+, Network+, CCNP Security, AZ-700/AZ-500, CISSP, or similar

About the Company

K

Kimley-Horn

Kimley-Horn keeps two groups of people at the center of its business: its clients and its staff. Past president Ed Vick said, "We have no reason to exist except to serve our clients." That intense focus on providing quality to the people we serve has made Kimley-Horn one of the nation's top consulting firms in every discipline we practice.

But the firm's core purpose, articulated by its leadership and lived out daily, is "to provide an environment for our people to flourish." We know that people are fulfilled, motivated, and challenged in different ways. In order to foster our individual aspirations, we support our people as they grow into roles and take on responsibilities that are important to them. Growing professionally, having fun with our colleagues, and finding satisfaction in our work are central to our way of life.

To that purpose we add core values: "honesty, integrity, and ethics; exceptional client service; high expectations; sharing and caring; sustained profitability." Our core values and core purpose provide a foundation for the way we approach our business. Our vision is long-term and our expectation is always to perform with quality, for the sake of both groups at the center of our firm.

Through their work, our people discover untapped talents and interests. At Kimley-Horn we work hard to allow that to happen. We have college students who started as traffic engineers now working on ITS projects. We have former administrative assistants who are now human resources professionals and former marketing coordinators who are now transportation planners.

We provide the environment. We want you to take advantage of it and flourish!
