Platform Security-Senior RNTSK0041235 / Network Security Engineer

As a Senior Cybersecurity Engineer (Edge Defense), you will play a pivotal role in the end-to-end lifecycle of our perimeter and cloud security products. Your primary focus will be the global engineering, adoption, and optimization of our Edge security stack, including Next-Generation Firewalls (NGFW), DDoS mitigation, and Zero Trust Network Access (ZTNA). You are a technical "implementer" responsible for designing robust, high-availability architectures that protect our global network from external threats while enabling secure, seamless access to multi-cloud environments. By leveraging an "Automation-First" mindset, you will transform traditional perimeter controls into scalable, code-driven security services, ensuring digital boundaries remain resilient in an evolving threat landscape.

• Infrastructure as Code (IaC): Proficiency in Terraform and GitHub to maintain version-controlled, reproducible security configurations.
• Scripting & Integration: Strong skills in Python or Go to build custom API integrations between security platforms and internal orchestration tools.
• DDoS Mitigation: Experience managing specialized DDoS protection services (e.g., Akamai, Cloudflare, or F5).
• Governance Frameworks: Familiarity with NIST, ISO 27001, and FAIR data principles.

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.

Requirements

Edge Architecture & Engineering

• Perimeter Defense Mastery: Lead the end-to-end deployment, configuration, and maintenance of Next-Generation Firewalls (Palo Alto, Fortinet), ensuring high availability (Active/Active & Active/Passive) and optimal inspection performance across global entry points.

  Zero Trust Transition: Architect and implement ZTNA solutions to move beyond legacy VPNs, focusing on granular, application-level access and identity-aware security policies.

• Multi-Cloud Network Security: Engineer and manage cloud-native security controls within AWS, Azure, and GCP, ensuring consistent security posture across hybrid and multi-cloud environments.
• DDoS & Threat Mitigation: Design and refine DDoS protection strategies and automated threat prevention policies (SSL decryption, IPS/IDS) to shield critical infrastructure from sophisticated external attacks.

Product Lifecycle & Evolution

• Lifecycle Governance: Oversee the delivery of Edge solutions from initial design through build, global rollout, and continuous optimization, ensuring that all security controls are reliable, scalable, and documented.
• Edge Innovation: Proactively identify emerging trends in Edge computing and SASE (Secure Access Service Edge) to inform the product roadmap and maintain a competitive advantage in network defense.

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.
• Security Observability: Develop advanced monitoring dashboards and telemetry to provide real-time visibility into edge traffic patterns, attack surfaces, and the health of the security stack.
• 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.
• Self-Service & Enablement: Build and maintain automate
