Information Security Engineer, Network Security Engineering

This is a fully remote position, open to applicants in Texas.

📋 Description

• Act as the main subject matter expert for Palo Alto Networks technologies, including NGFWs, Cloud NGFW, Panorama, Web Application Firewall, Content Delivery Network, API Security, IDS/IPS, and DDoS prevention.

• Take ownership of onboarding, policy tuning, and lifecycle management for WAF and CDN platforms; oversee firewall ruleset optimization, IDS/IPS tuning, and DDoS protection configuration.

• Collaborate with internal teams to facilitate the global deployment, tuning, and operational management of URL filtering and TLS decryption throughout the network environment.

• Spearhead API security initiatives — ensuring that API traffic is routed through security tools, identifying vulnerabilities, and collaborating with application teams on resolutions.

• Direct the troubleshooting of intricate, multi-layer global network and application challenges — from packet captures on inter-continental BGP topologies to addressing WAF false-positive issues.

• Work alongside business and application teams to generate clear, actionable security documentation, change proposals, and executive-ready reports.

• Evaluate current network security architectures, processes, and procedures to pinpoint gaps and drive significant enhancements.

• Set up and report on defensive strategies against advanced threat actor tactics; maintain up-to-date knowledge of the evolving threat landscape and the effectiveness of our defensive measures.

• Clearly articulate complex technical issues and solutions to both global engineering teams and C-suite stakeholders.

• Advocate for the broader Security team’s initiatives, extending beyond just Network Security Engineering.

• Engage in the maintenance and tuning of all network security technologies, including WAFs, CDNs, VPNs, and application-aware firewalls.

• Utilize and contribute to automation pipelines for global firewall rule deployment and policy management across the network environment.

• Leverage security tooling telemetry and data collection automations to generate actionable reports and metrics for internal teams and executive stakeholders.

⛳️ Requirements

• Over 5 years of practical network security engineering experience in designing and implementing enterprise-scale security solutions.

• Expert-level knowledge of Palo Alto Networks technologies — NGFWs, Panorama policy management, and PAN-OS; PCNSE or PCNSC certification is highly preferred.

• Proficient troubleshooting capabilities across network and application layers, including packet capture analysis on complex, dynamically routed architectures.

• In-depth understanding of layer 7 web application technologies and WAF/CDN platforms (such as Akamai, Cloudflare, Imperva, F5) — including onboarding, policy tuning, break/fix troubleshooting, and operational management.

• Strong foundation in API security — ensuring API traffic is routed through security tools, assessing identified vulnerabilities, and collaborating with application teams for remediation.

• Comprehensive knowledge of HTTP/application security topics: TLS interception, SQL injection, XSS, CSRF, command injection, LFI/RFI, rate limiting, bot detection, geo-blocking, and sinkholing.

• Intermediate to advanced knowledge of network routing and switching, with a focus on DNS, TCP/IP, IPsec, TLS, GRE, OSPF, and BGP.

• Proficient in at least one scripting language (Python preferred) and familiar with Linux/CLI tools.

• Working knowledge of public cloud environments (Azure, AWS, GCP).

• Experience with at least one SIEM platform for log analysis, behavioral analytics, and rule tuning.

• Strong written and verbal communication skills, capable of presenting to both technical and non-technical audiences.

• Proven history of taking ownership in unstructured environments — navigating ambiguity, making informed decisions with incomplete information, building stakeholder consensus, and implementing security enhancements without awaiting top-down direction.

🏝️ Benefits

• 401(k) plan with matching company contributions.

• Comprehensive Medical, Dental & Vision Care.

• Paid parental leave at 100% of salary.

• Paid Time Off and Company Holidays.
