Job description

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).

  • Regulated Industry: Experience working in highly regulated environments (e.g., Pharmaceuticals, Healthcare, or Finance) is a significant plus.

Technical Skills

  • NGFW Expert: Expert-level knowledge of Palo Alto and/or Fortinet platforms, including advanced threat prevention, SSL decryption, and high-availability design.

  • DDoS Mitigation: Experience managing specialized DDoS protection services (e.g., Akamai, Cloudflare, or F5).

  • ZTNA & Remote Access: Proficiency in modern Zero Trust architectures and SASE frameworks (e.g., Zscaler, Prisma Access).

  • Multi-Cloud Networking: Strong understanding of cloud networking components (VPCs, VNETs, Transit Gateways, Cloud Firewalls).

  • Network Foundations: Deep understanding of core protocols (BGP, OSPF, DNS, TLS/SSL) and how they intersect with security enforcement.

Skills below will be considered a plus:

  • Vendor certifications: Fortinet NSE or Palo Alto Networks PCNSA PCNSE or Cisco CCNP Security

  • Cybersecurity certification: CISSP

  • 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.
