Project Summary
We are launching a comprehensive initiative to modernize network architecture across corporate offices, branch locations, and manufacturing plants. This project focuses on standardizing LAN and edge designs, upgrading firewall security platforms, and simplifying IT/OT segmentation through a migration to Prisma SD-WAN.
Architecture & Objectives
The Senior Network Engineer will execute a standardized Core/Distribution/Access model to improve scalability and performance. Key objectives include:
- Gateway Migration: Moving select VLAN gateways from firewalls to Core Switch SVIs to optimize traffic flow.
- Security Refresh: Replacing legacy PA-440 firewalls with PA-1420 platforms.
- Segmentation: Optimizing OT network environments with dedicated IT/OT core switching and reduced firewall zone complexity.
- SD-WAN Standardization: Transitioning edge infrastructure from VeloCloud to Prisma SD-WAN.
Detailed Scope of Work
1. Firewall & Security Infrastructure
- Perform physical rack, cable, and power installation of new PA-1420 units.
- Execute complex configuration migrations involving security zones, NAT, VPNs, and granular policies.
- Enable dynamic routing and validate overall system health post-migration.
2. LAN & SVI Gateway Migration
- Configure VLANs and SVIs on IT/OT core switches to handle routing locally.
- Update routing tables across the firewall and SD-WAN environment.
- Test and validate inter-VLAN routing and critical application connectivity.
3. SD-WAN Deployment (VeloCloud to Prisma)
- Rack and provision Prisma ION devices.
- Migrate active WAN circuits while validating tunnels, security policies, and failover redundancy.
- Decommission and inventory legacy VeloCloud equipment.
4. Deployment & Validation
- Conduct site readiness checks and device staging.
- Lead cutover execution during designated maintenance windows to minimize business impact.
- Perform exhaustive testing, including failover validation, IT/OT segmentation checks, and user connectivity verification.
Qualifications
Technical Qualifications
- Expertise: Extensive experience with Palo Alto Firewalls (PA-1420 preferred) and Prisma SD-WAN.
- Routing & Switching: Advanced proficiency in L2/L3 switching, SVI configuration, and dynamic routing protocols.
- IT/OT Knowledge: Experience working in manufacturing environments with specific IT/OT segmentation needs.
- Tools: Ability to work with standardized templates, checklists, and repeatable build-test-cutover processes.
