Designs, secures, and automates enterprise networks spanning on-prem, cloud, and hybrid environments using Palo Alto firewalls, SD-WAN, Python, Ansible, and Terraform.
Responsibilities
• Design, implement, maintain, and optimize enterprise network infrastructure across on-premise data centers, branch locations, and hybrid cloud environments.
• Configure, monitor, and troubleshoot routing and switching technologies to ensure network stability, performance, and scalability across multi-site environments.
• Deploy, administer, and support Palo Alto firewalls, including policy management, NAT, VPN configuration, threat prevention, URL filtering, and security rule optimization.
• Manage and maintain network security technologies, including firewalls, IDS/IPS, VPNs, segmentation controls, and secure remote access solutions.
• Support network segmentation and isolation strategies to protect sensitive data, critical systems, and regulatory compliance requirements.
• Implement and support secure connectivity between on-premise infrastructure, cloud platforms such as AWS and Azure, and remote users.
• Configure and maintain load-balancing solutions to support high availability, efficient traffic distribution, and optimal application performance.
• Support the deployment and operational management of technologies such as SD-WAN, SDN, and other modern networking solutions to improve agility and efficiency.
• Monitor network health, availability, and capacity; perform performance analysis, troubleshooting, and proactive tuning to minimize downtime and service disruptions.
• Create and maintain network documentation, including diagrams, configurations, standard operating procedures, and implementation plans.
• Collaborate with cybersecurity, cloud engineering, systems, and application teams to ensure network solutions meet technical, business, and security requirements.
• Develop and implement network automation solutions using scripting and infrastructure-as-code tools to streamline provisioning, configuration management, compliance checks, and repetitive operational tasks.
• Leverage tools such as Python, Ansible, Terraform, or APIs to automate network deployments, firewall policy administration, monitoring, and reporting.
• Evaluate and support emerging technologies that improve network operations, visibility, and service reliability.
• Stay current on networking, security, and automation best practices to continuously modernize the network environment.
Required Skills and Qualifications
• Bachelors degree in Computer Science, Information Technology, or a related field, or equivalent practical experience.
• 5+ years of progressive experience in network engineering supporting enterprise-level network environments.
• Strong hands-on experience with routing and switching technologies and configurations in enterprise environments (e.g., Cisco, Juniper, or similar platforms).
• Proven experience managing and troubleshooting Palo Alto firewalls, including security policies, NAT, VPNs, and advanced threat prevention features.
• Strong knowledge of network security technologies, including firewalls, IDS/IPS, VPNs, segmentation, and secure access controls.
• Experience supporting secure networking solutions across both on-premise and cloud environments, including AWS and Azure.
• Familiarity with SDN, SD-WAN, and modern network design principles.
• Experience with load balancing, high availability design, and performance optimization.
• Hands-on experience with network automation using scripting languages such as Python and automation tools/frameworks such as Ansible, Terraform, or REST APIs.
• Experience with network monitoring, capacity planning, performance analysis, and root cause troubleshooting.
• Strong analytical, problem-solving, organizational, and communication skills.
• Relevant industry certifications such as CCNP, PCNSE, AWS Certified Advanced Networking, Azure Network Engineer Associate, or similar are highly desirable.
