Senior Cybersecurity Engineer for Internal Network Defense

Job Description

As a Senior Cybersecurity Engineer for Internal Network Defense, you will be the primary guardian of our internal environment, protecting our most sensitive segments—from manufacturing plants and research labs to warehouses and corporate offices. Your mission is to architect and enforce robust "East-West" segmentation, preventing lateral movement and securing the diverse environments that drive our core business. This is a technical "implementer" role where you will architect, design, build, and operate high-performance security boundaries using a dual-vendor strategy (Palo Alto and Fortinet). Beyond traditional enforcement, you will champion the adoption of AI-driven insights to identify latent risks and define the safe boundaries for automated security workflows, ensuring our internal network is resilient, compliant, and prepared for machine-speed threats.

Job Responsibilities

Architecture, Design & AI Ambition

- Segmentation Strategy: Design, develop and document robust network segmentation architectures leveraging Fortinet and Palo Alto firewalls to meet complex business and security requirements
- AI-Driven Risk Discovery: Actively explore and integrate AI opportunities to analyze internal traffic patterns and identify emerging security risks within complex Manufacturing and Lab environments
- Automated Guardrails: Define and establish clear boundaries and governance for automated workflows, ensuring that machine-driven policy changes remain within safe, predictable parameters
- Solution Blueprints: Create detailed network diagrams, technical design documents, and implementation plans for new segmentation environments (Labs, Manufacturing, Research)

Implementation & Deployment

- Firewall Engineering: Configure, deploy, and manage Palo Alto Networks (PA-Series, VM-Series) and Fortinet FortiGate firewalls at scale
- Centralized Management: Utilize Panorama and FortiManager to enforce consistent security policies, NAT rules, VPNs (IPSec/SSL),



and advanced routing features
- Infrastructure Evolution: Lead the migration and upgrade of existing internal firewall infrastructure, ensuring zero-downtime transitions in critical environments
- Operational Excellence & Visibility
- Technical Subject Matter Expertise: Serve as the lead engineer for complex network security escalations, performing deep-packet analysis and root-cause investigations to implement long-term architectural fixes
- Validated Environments: Apply security best practices within validated (GxP) environments, ensuring compliance with manufacturing and healthcare regulations
- Continuous Improvement: Stay current with emerging threats, vulnerabilities, and security technologies to proactively refine internal defenses
- Automation & Orchestration: Manage security policies as code while continuously improving automation workflows and cross-platform orchestration to eliminate manual friction, reduce operational overhead, and ensure consistent, high-speed security enforcement
- On-Call Readiness: Available for on-call support on a rotating schedule to ensure the continuous availability and integrity of integral edge security services

Qualifications

Education / Experience

- Educational Background: Bachelor’s degree in Computer Science, Software Engineering, Information Security, or a related technical field
- Professional Experience: 3+ years of experience in designing, deploying, and supporting Next-Generation Firewalls (NGFW) in large enterprise environments
- Automation Engineering: Proven experience using Ansible, Terraform, or Python to manage network security infrastructure at scale
- Large-Scale Infrastructure:



Experience managing security controls in complex, global environments involving thousands of diverse device profiles (IoT, Medical, Corporate)
- Regulated Industry: Experience working in highly regulated environments (e.g., Pharmaceuticals, Healthcare, or Finance) is highly preferred

Technical Skills

- Palo Alto Mastery: Deep knowledge of PA-Series, Panorama, App-ID, User-ID, WildFire, and Threat Prevention
- Fortinet Expertise: Extensive hands-on experience with FortiGate, FortiManager, FortiAnalyzer, and the Fortinet Security Fabric
- Security Foundations: Solid understanding of security concepts, trends, and best practices, specifically for "Defense in Depth" within internal networks
- Networking Depth: Strong foundation in core routing/switching, VPN architectures, and network protocols

Leadership Skills

- Communication: Strong ability to build trust with network and infrastructure experts and explain complex security policy concepts to non-technical stakeholders
- Innovation & Curiosity: A relentless passion for staying ahead of threat actors by researching emerging network security trends and automated enforcement techniques
- Thriving in Ambiguity: Ability to navigate global complexity and drive clarity when translating high-level security requirements into functional network policies
- Self-Starter: Proven ability to manage technical workstreams from concept to production with minimal supervision, taking full ownership of the Edge Defense product lifecycle

Additional Qualifications

- Demonstrated ability to mentor colleagues with less experience and provide guidance on cybersecurity best practices and analysis techniques
- Strong facilitation, communication, and conflict resolution skills to ensure alignment across multiple product squads and complex stakeholder networks
- Demonstrated interpersonal, collaborative and commitment to operational excellence skills
