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.

3. 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 global edge security services.
