What you will do

• Own and continuously evolve the cloud WAF stack, defining and tuning rules, policies, and traffic flows to protect public APIs and frontends.
• Build and maintain end-to-end HTTP/HTTPS observability, including structured logging, dashboards, alerting, and synthetic checks.
• Drive WAF and networking infrastructure as code (IaC), fully integrated into CI/CD pipelines, ensuring changes are repeatable, auditable, and secure.
• Design and operate VPCs and core network services (routing, DNS, VPNs, and third-party connectivity), ensuring resilience and scalability.
• Automate key deployment and configuration workflows, minimizing manual work and operational risk.
• Lead and actively participate in incident response for network and WAF-related security, performance, and availability events.
• Partner closely with Information Security and Compliance to ensure the network and WAF architecture meets regulatory and industry standards (e.g., PCI, SOX).

Requirements

• Solid, hands-on experience managing and configuring WAFs in cloud environments (ideally multi-provider), protecting high-traffic web applications and APIs.
• Strong knowledge of networking and protocols (TCP/IP, HTTP/HTTPS, TLS, DNS, routing, load balancers, VPN/IPsec).
• Practical experience with at least one cloud provider (ideally AWS) and its networking components (VPC, subnets, security groups, NACLs, routing, load balancers).
• Real-world experience with Infrastructure as Code (Terraform or similar) and CI/CD pipelines to manage network and WAF changes.
• Experience in observability and monitoring: log, metric, and trace analysis, building actionable dashboards and alerts.
• English: good enough to document and coordinate in writing and in calls.

Nice to have

• Exposure to PCI-DSS framework or any other relevant security standard.
• Good knowledge of security architectures, both monoliths and microservices.
• Good understanding about Machine learning, RAG, and LLM logic in the context of security results.
• Previous work in high-criticality environments (payments, fintech, banking, global e-commerce).
• Background as a network/security architect, able to propose end-to-end designs.

Culture & Benefits

• Collaborative environment with Information Security and Compliance teams.
• Focus on maintaining strong security and reliability posture.
