- Professional
- Bureau à Kennesaw
Position Overview: A Firewall Engineer II is a mid-level cybersecurity professional responsible for designing, implementing, and maintaining an organization's network security, with a special focus on firewall infrastructure. This role involves more complex duties than a junior position, requiring experience in analyzing security events, troubleshooting advanced issues, and contributing to security strategy under the guidance of senior engineers.
Technical duties
- Firewall administration:Design, configure, and manage next-generation firewalls, including policy rulebases, network address translation (NAT), and secure virtual private network (VPN) tunnels.
- Threat analysis:Conduct advanced security event detection and threat analysis by monitoring firewall logs and alerts for suspicious activity.
- Troubleshooting:Provide Tier II support and perform root cause analysis for firewall-related incidents, connectivity issues, and performance problems.
- Network security:Implement and administer other perimeter security solutions, including intrusion detection and prevention systems (IDS/IPS), web application firewalls (WAFs), and load balancers.
- Upgrades and patching:Plan, coordinate, and execute upgrades, patches, and code updates for network security devices.
Documentation and compliance
- Documentation:Develop and maintain detailed network security documentation, standard operating procedures, and runbooks.
- Compliance:Ensure the firewall and network security configurations comply with internal and external policies, industry best practices, and regulatory requirements (e.g., NIST, PCI, HIPAA).
- Change management:Adhere to established change control policies, ensuring all changes to the network infrastructure are properly documented, approved, and tracked.
Security posture enhancement
- Reduced attack surface: Decrease the number of successful intrusion attempts by a specific percentage (e.g., 20%) through the implementation of new security measures.
- Improved readiness: Achieve a high score (e.g., 95% or higher) in an external cybersecurity readiness assessment.
- Policy optimization: Conduct a quarterly review and audit of all firewall rules and successfully remove or decommission a specific number of outdated or unnecessary rules to reduce complexity and minimize risk.
Incident response and threat mitigation
- Faster detection: Reduce the Mean Time to Detect (MTTD) cybersecurity incidents by a specific percentage (e.g., 30%) by deploying enhanced monitoring and detection mechanisms.
- Quicker resolution: Decrease the Mean Time to Respond (MTTR) to cybersecurity incidents by a specific percentage (e.g., 40%) through streamlined incident response workflows.
- Prompt alerts: Configure and validate a new alerting system that provides instant notifications for anomalous network events, enabling a quicker response.
Operational efficiency and performance
- Improved network performance: Optimize firewall and security policies to improve network throughput and reduce latency, leading to quantifiable performance improvements. For example, reduce application latency by 15% by fine-tuning firewall inspection settings.
- Proactive issue resolution: Implement a new monitoring system to detect and address firewall issues proactively, reducing the number of critical firewall incidents by a specific percentage.
- Resource optimization: Reduce bandwidth misuse and improve bandwidth availability for critical business activities through better monitoring and policy enforcement.
Infrastructure management and documentation
- Standardized documentation: Create and maintain up-to-date documentation for all firewall policies, standard operating procedures (SOPs), and network diagrams, making resources accessible to the rest of the team.
- Successful upgrades: Plan, test, and execute the upgrade of all network firewalls to the latest firmware version, completing the project without any unplanned downtime.
- Compliance readiness: Successfully complete a firewall compliance audit, ensuring all devices and policies adhere to regulatory standards and internal security guidelines.
Leadership and mentorship
- Knowledge sharing: Develop and lead training sessions for junior engineers on advanced firewall configurations and troubleshooting, resulting in a measurable improvement in their ability to resolve issues.
- Enhanced team skills: Mentor a new team member and successfully onboard them, resulting in their ability to handle standard firewall change requests independently within three months.
Streamlined processes:
- Develop and implement a new, automated process for firewall change management, reducing the average time to fulfill a standard request by 50%.
Willingness to provide after-hours project work and support (as required)
Qualifications:
Experience
- Typically requires 2–5 years of experience in network security or a related IT field.
- Significant hands-on experience with major firewall platforms, such as Palo Alto Networks (including Panorama), Cisco ASA, Fortinet, or Check Point.
Technical skills
- Strong understanding of core networking concepts, including TCP/IP, routing protocols (e.g., BGP, OSPF), IP Subnetting, and VLANs.
- Proficiency with security tools and technologies such as VPN, IDS/IPS, network monitoring, and security information and event management (SIEM) systems.
- Experience with cloud security principles in environments like AWS or Azure is highly desirable.
Soft skills
- Excellent problem-solving and analytical skills.
- Strong verbal and written communication skills to collaborate with technical teams and other business units.
