- Configure and manage FortiGate firewalls, perimeter ACLs, and remote-access solutions, including break-glass access paths.
- Implement and validate security groups, Network ACLs (NACLs), egress restrictions, and network segmentation controls to maintain the air-gap security posture.
- Integrate security logs and telemetry from infrastructure, platform, and application sources with the SIEM platform.
- Validate deployment and active operation of endpoint and workload protection across recovered servers, containers, and cloud workloads.
- Ensure vulnerability management and Cloud Security Posture Management (CSPM) tools have visibility into the isolated recovery environment.
- Collaborate with security stakeholders on policy definition, security controls reviews,



and compliance requirements for regulated workloads.

Mandatory Skills :

- 8+ years of experience in AWS networking and cloud security engineering.
- Strong hands-on expertise in AWS Transit Gateway, VPC routing, and Route 53 public/private hosted zones.
- Experience configuring and managing FortiGate firewalls and perimeter access controls.
- Strong understanding of network isolation, segmentation, and secure network architecture for regulated environments.
- Hands-on experience implementing security groups, NACLs, egress restrictions, and cloud security guardrails.
- Experience integrating cloud infrastructure and application logs with SIEM platforms.
- Knowledge of EDR, CSPM, vulnerability management, and workload protection solutions.
- Experience designing and validating secure remote-access mechanisms and emergency access procedures.

Preferred Experience :

- Experience designing isolated recovery environments or disaster recovery network architectures.
- Familiarity with maintaining air-gap security controls during and after recovery operations.
- Experience working in regulated enterprise environments with stringent security and compliance requirements.
- Ability to collaborate with security teams on policy definition and security control reviews.

Key Deliverables :

- Secure network isolation setup for the isolated recovery workplace.
