Descrição da oferta de emprego

Our nearshore expertise sets us apart. We specialize in placing high-caliber engineers into complex international technology environments, supporting organizations operating secure, highly available and business-critical infrastructure.

We are looking for a Senior Network Security Engineer | Palo Alto, Fortinet & F5

To join an enterprise Secure Connectivity & Application Protection environment responsible for protecting connectivity between users, datacenters, cloud platforms and business-critical applications.

The engineering scope covers different layers of the same security ecosystem: Next-Generation Firewalls and network segmentation, secure connectivity, Application Delivery, WAF/WAAP and hybrid/cloud security.

We are looking for specialists across different technical workstreams. Deep expertise in Palo Alto, Fortinet or F5 is more important than having experience with the entire stack.

Skills

• +5 years of experience within Network Security / Security Engineering in enterprise environments;
• Strong hands-on expertise in at least one core technology domain: Palo Alto Networks, Fortinet or F5 BIG-IP;
• Next-Generation Firewall engineering covering security policies, NAT, VPN, segmentation and controlled network communication;
• Palo Alto environments including PAN-OS, Panorama and enterprise firewall management;
• Fortinet environments including FortiGate, with exposure to centralized management and security policy administration;
• F5 BIG-IP / Application Delivery technologies supporting application traffic, load balancing, availability and secure publishing;
• WAF / WAAP concepts for protecting web applications and APIs against application-layer threats;
• Strong understanding of TCP/IP, DNS, HTTP/S, TLS, routing and network traffic flows;
• Troubleshooting across network, firewall and application layers, identifying connectivity, policy and traffic-management issues;
• Security across hybrid environments, connecting datacenter, cloud and externally exposed services;
• Professional English within international engineering environments.

Your Responsibilities

• Engineer and evolve secure enterprise connectivity across datacenter, cloud and distributed infrastructure;
• Design and maintain Next-Generation Firewall controls governing communication between users, networks, applications and external services;
• Configure and troubleshoot Palo Alto or Fortinet security environments according to your main area of specialization;
• Define and maintain firewall policies, NAT rules, VPN connectivity and network segmentation, ensuring controlled communication between different security zones;
• Analyse complex incidents involving routing, connectivity, firewall policies, network flows and application access, identifying root causes rather than applying temporary fixes;
• Support secure exposure of business-critical applications through Application Delivery Controllers, load balancing and traffic-management technologies;
• Engineer and operate F5 BIG-IP environments, contributing to availability, performance and secure application delivery;
• Implement and maintain WAF / WAAP policies protecting web applications and APIs exposed across internal, external and cloud environments;
• Analyse HTTP/S and TLS traffic flows, supporting troubleshooting and security controls across the application delivery layer;
• Contribute to security controls protecting hybrid and cloud connectivity, maintaining consistent policies between on‑premise and cloud-hosted environments;
• Participate in changes, migrations, upgrades and security improvements across large‑scale network and application-security infrastructure;
• Work alongside Network, Cloud, Infrastructure and Security teams to ensure connectivity, availability and security remain aligned across the environment.

We are particularly interested in three specialist profiles:

• Palo Alto Network Security — NGFW, Panorama, policies, segmentation and troubleshooting
• Fortinet Network Security — FortiGate, firewalling, secure connectivity and enterprise network protection
• F5 / Application Security — BIG-IP, Application Delivery, WAF/WAAP and Cloud Security
