What does a Sr Network Firewall Engineer do?

A Sr Network Firewall Engineer is responsible for designing, implementing, managing, and troubleshooting network firewall systems to protect an organization’s digital assets from unauthorized access and cyber threats. They evaluate network security needs, configure firewall policies, monitor for suspicious activity, and ensure compliance with security standards.

  • Coordinate with remote teams for cutover and validation
  • Perform initial connectivity and failover testing

Remote (Off-Site Work):

  • Complete advanced firewall configuration and rule migration
  • Optimize security policies and NAT configurations
  • Integrate with centralized management tools (e.g., FortiManager, FortiAnalyzer if applicable)
  • Perform post-deployment validation and troubleshooting
  • Document configurations, network diagrams, and change records
  • Support knowledge transfer and handoff to operations teams

Required Qualifications

  • Proven experience with Fortinet FortiGate firewall deployment and configuration
  • Strong hands-on experience with Cisco ASA and/or Palo Alto Networks firewalls
  • Solid understanding of:
    • Layer 3 networking (routing, VLANs, subnetting)
    • VPN technologies (IPSec, site-to-site tunnels)
    • NAT and firewall policy design
  • Experience performing firewall migrations and cutovers in production environments
  • Ability to work independently in remote and field environments
  • Strong troubleshooting and documentation skills

Preferred Qualifications

  • Experience working in utilities, energy, or critical infrastructure environments
  • Familiarity with substation networks and OT/ICS environments
  • Knowledge of security and compliance frameworks relevant to utilities (e.g., NERC CIP)
  • Experience with FortiManager and FortiAnalyzer
  • Relevant certifications (e.g., NSE 4/5/7, CCNP Security, PCNSE)

Work Structure

  • On-Site Requirement: ~1 day per location for hardware replacement and initial configuration
  • Remote Work: Remaining hours performed remotely for configuration, validation, and documentation
  • Travel: Required to multiple substation locations (regional travel expected)

Engagement Type

  • Contract / Project-based
  • Flexible scheduling based on site availability and project timeline
