Network Security Engineer

We are seeking a Network Security Engineer with strong experience with Palo Alto to help mature and optimize our global network security environment with a focus on Zero Trust architecture, alignment to NIST cybersecurity frameworks, and proactive risk reduction. This role is critical to ensuring that our firewall infrastructure and security posture evolve in step with business priorities, regulatory compliance, and industry best practices.

This hybrid role will be located in Tempe, Arizona.  

The ideal candidate brings deep experience in managing and refining Palo Alto Networks solutions across complex, hybrid enterprise environments. Beyond deployment, this position requires a strategic mindset—someone who can evaluate current controls, identify gaps, drive standardization, and lead continuous improvement efforts.

• Lead ongoing optimization of firewall policies, rulebase hygiene, and configuration standards across environments

• Define and enforce enterprise-wide security policy frameworks, including tagging standards, object naming conventions, and access control methodologies

• Refine and maintain authentication profile integrations (e.g., LDAP, SAML, RADIUS, MFA) to support granular, identity-based security models

• Collaborate with stakeholders to align firewall controls and network segmentation to business risks and priorities

• Conduct periodic assessments and gap analyses to measure posture against best practices, compliance requirements, and internal audit standards

• Participate in cross-functional projects to ensure network security is embedded in infrastructure lifecycle processes (e.g., change management, architecture reviews)

• Maintain documentation, reference architectures, and runbooks to support knowledge transfer, audit readiness, and operational excellence

• Provide mentorship and guidance to junior team members and collaborate with broader InfoSec, cloud, and infrastructure teams

• Support security incident response by providing firewall data, analysis, and rule adjustments as needed

What you'll bring:

• 5–8+ years of experience managing enterprise firewall environments, ideally in regulated or highly available environment

• Expertise with Palo Alto Networks solutions (PA Series firewalls, Panorama, Prisma Access)

• Deep understanding of Zero Trust principles and ability to apply them in real-world enterprise environments

• Strong grasp of NIST CSF, 800-207, and other industry-aligned security architecture and control frameworks

• Experience developing and managing firewall policy baselines, segmentation strategies, and governance documentation

• Proficiency in managing authentication profiles and integrating identity platforms (e.g., Okta, Azure AD) with network controls

• Experience in hybrid cloud and IaaS environments (e.g., AWS, Azure) and their impact on network security architecture
   

Certifications:

• PCNSE (Palo Alto Networks Certified Network Security Engineer) – Strongly Preferred

• CCNP Security, CCNP Enterprise, or CCIE – Preferred
