Essential duties include the following:

Design, implement, operate, and improve secure enterprise network architectures across on-premises, cloud, and hybrid environments.

Deploy, configure, manage, and troubleshoot Palo Alto Networks and Cisco firewalls, including security policies, NAT policies, security zones, objects, application controls, and access-control policies.

Design and implement network segmentation, micro-segmentation, and isolation controls to reduce attack surfaces and limit lateral movement.

Perform firewall migrations, upgrades, configuration changes, policy optimization, and complex troubleshooting.

Develop and maintain network security standards, architecture documentation, network diagrams, implementation procedures, and operational runbooks.

Design, implement, and troubleshoot remote-access VPN solutions and site-to-site IPsec tunnels, including authentication, encryption, routing, and tunnel connectivity.

Establish secure connectivity among corporate offices, data centers, cloud environments, remote users, and third-party organizations.

Design, implement, and troubleshoot enterprise routing architectures, including BGP, OSPF, route redistribution, route filtering, route summarization, and routing policies.

Apply strong knowledge of TCP/IP, subnetting, VLANs, NAT, DNS, DHCP, network segmentation, high availability, and redundancy.

Design and implement secure AWS VPC and Microsoft Azure VNet architectures, including subnets, route tables, network security controls, and hybrid connectivity.

Evaluate cloud network architectures and configurations for security risks, misconfigurations, and control gaps and support cloud transformation initiatives.

Configure and maintain IDS/IPS, firewall logging, and network security telemetry and coordinate integration into centralized monitoring and incident-response workflows.

Serve as a senior technical resolver for complex network security incidents and service disruptions and lead or contribute to root-cause analysis and corrective actions.

Participate in the defined on-call rotation and support major technical escalations.

Support compliance and audit activities by maintaining controls, producing audit-ready evidence, and coordinating remediation related to PCI DSS, SOC 2, NIST, ISO 27001, and other applicable requirements.
