Job Description

Job Summary

We are seeking a highly skilled Network Engineer to design, implement, maintain, and troubleshoot our core enterprise and data center network infrastructure. In this role, you will be directly responsible for managing high-performance networks utilizing VXLAN with BGP EVPN, securing environments using Palo Alto Firewalls, and maintaining reliable site-to-site connectivity. The ideal candidate is a hands-on technical expert with deep routing, switching, data center virtualization, and network security expertise.

Key Responsibilities

Data Center Architecture: Design, deploy, and maintain spine-leaf topologies using VXLAN overlay networks with BGP EVPN control planes for scalable, multi-tenant data center environments.

Network Configuration & Switching: Configure and maintain enterprise networks, explicitly managing VLAN segmentation, trunking, inter-VLAN routing, and link aggregation across core and access switches.

Advanced Routing: Implement and optimize dynamic routing protocols, with a heavy focus on BGP (Border Gateway Protocol) configuration, path manipulation, policy routing, and OSPF.

Firewall Management & Security: Deploy, configure, and manage Palo Alto Networks Next-Generation Firewalls (NGFW), including security policies, NAT rules, threat prevention, and URL filtering.

VPN & Secure Access: Establish, maintain, and monitor secure site-to-site IPsec VPN tunnels connecting remote offices, data centers, and cloud environments, alongside deploying and maintaining Zscaler App Connectors for secure private application access (ZPA).

Troubleshooting & Support: Act as the Tier 3 escalation point to diagnose and resolve complex network connectivity issues, routing loops, asymmetric routing, packet loss, and performance bottlenecks.

Documentation: Author and maintain highly detailed topology diagrams (Logical/Physical), configuration baselines, IP address management (IPAM), and standard operating procedures.
