Job Type
Description
The purpose of the role is to ensure that the FortiGate/FortiWeb environment is transparent, standardized, change-managed, and auditable, and that it aligns with NIS2 compliance requirements.
The position works closely with hybrid/cloud security areas (e.g., M365 E5 Security), as well as containerized platform security (NeuVector) — in these areas, it is not an ownership role, but rather an integration/collaboration-focused role.
Responsibilities:
- Operate and maintain FortiGate and FortiWeb environments, including firewall policies, routing, VPNs, WAF tuning, certificate management, and virtual patching.
- Perform advanced troubleshooting and root-cause analysis using logs and debug-level diagnostics.
- Manage infrastructure changes through GitOps practices, ensuring version-controlled, transparent, and peer-reviewed deployments.
- Drive security engineering initiatives, including firewall policy optimization, security hygiene improvements, and VPN modernization projects.
- Support NIS2 compliance by implementing technical security controls and providing audit-ready evidence and documentation.
- Collaborate closely with platform and security teams across hybrid cloud environments, including container and runtime security solutions such as NeuVector.
Requirements:
- Hands-on experience operating FortiGate firewalls in enterprise environments (or equivalent enterprise-grade firewall platforms).
- Solid networking fundamentals, including TCP/IP, VLANs, switching, and routing.
- Strong troubleshooting and diagnostic skills, with experience analyzing logs and performing debug-level investigations.
- A disciplined and quality-focused approach to work, with openness to controlled, documented, and review-driven change management processes.
- Ability to work collaboratively with infrastructure, platform, and security teams.
- Experience supporting security operations in complex IT environments.
Advantages:
- Experience operating FortiGate firewalls or other enterprise-grade firewall platforms.
- Good understanding of networking concepts, including TCP/IP, VLANs, switching, and routing.
- Experience troubleshooting network and security issues using logs and debug tools.
- Familiarity with controlled, documented, and review-driven change management practices.
- Experience working closely with infrastructure, platform, and security teams.
- Exposure to security operations within complex enterprise environments.
