Your responsibilities:

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

We are looking for you, if you have:

Education / Experience

  • Educational Background: Bachelor’s degree in Computer Science, Software Engineering, Information Security, or a related technical field.
  • Perimeter Security Mastery: 5+ years of hands-on experience in designing and managing enterprise-grade Firewall environments (specifically Palo Alto and/or Fortinet).
  • Cloud Security Expertise: Proven track record of implementing network security controls in at least two major cloud providers (AWS, Azure, or GCP).
  • Perimeter & Inspection Expertise: Proven track record in configuring and maintaining Palo Alto Next-Generation Firewalls (NGFW), including TLS inspection, User identification, WildFire, Threat Prevention, URL Filtering and GlobalProtect.
  • 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).
