About the Role
We are seeking an experienced Network Security Engineer to join a dynamic security team focused on enterprise-scale firewall architecture and implementation. This is a hands-on engineering position—not a traditional network route/switch role—ideal for professionals passionate about firewall technologies, network protection, and securing large, complex environments.
You’ll work with a team that manages firewall rules, security policies, and network access controls across multiple data centers and office locations nationwide. This role plays a critical part in ensuring the organization’s security posture as new data centers are built and legacy systems are modernized.

Key Responsibilities

• Design, implement, and manage firewall rules and security policies across Palo Alto, FortiGate, and Cisco FTD environments.
• Execute business-as-usual (BAU) firewall rule changes and handle ServiceNow ticket requests.
• Troubleshoot connectivity issues and provide firewall rule modifications to support business units.
• Participate in after-hours firewall implementations (typically once per week, post-8pm ET).
• Contribute to ongoing data center migration projects, including firewall setup, rule replication, and environment configuration.
• Collaborate with team members and stakeholders to maintain network security standards and support continuous improvement initiatives.
• Ensure that security controls are consistently applied across on-premises and cloud-connected systems.
  

• 5 years of hands-on experience managing, implementing, and supporting firewalls in large enterprise environments.
• Proficiency with Palo Alto firewalls required; experience with FortiGate and Cisco FTDs strongly preferred.
• Strong understanding of network security concepts, firewall rule architecture, and access control policies.
• Experience troubleshooting firewall-related network connectivity and security incidents.
• Familiarity with security tools and concepts such as VPN, proxy, and DDoS protection.
• Ability to work independently, prioritize effectively, and solve problems in a fast-paced environment.
• Excellent communication and documentation skills.
  

• Vendor-specific security certifications (e.g., Palo Alto, FortiGate).
• Cloud exposure—AWS preferred, Azure acceptable.
• Scripting or automation knowledge (Python, PowerShell, Ansible, Terraform, etc.).
• Previous experience working in regulated or enterprise security environments.
• Familiarity with Agile/Scrum environments.
