• Maintain network security policy management via FireMon; contribute to access path analysis and rule lifecycle management.
• Manage Proxmox-based virtualization as it relates to network-adjacent workloads and VM/LXC networking.
• Coordinate with vendors and carriers to manage WAN circuits, resolve outages, and drive cost optimization.
AWS Network Design & Operations
• Design, deploy, and maintain AWS Virtual Private Clouds (VPCs) including subnet design, CIDR allocation, route tables, internet gateways, and NAT gateways across multi-account and multi-region environments.
• Architect and manage VPC-to-VPC connectivity via VPC Peering, AWS Transit Gateway, and PrivateLink to support secure, scalable inter-service communication.
• Configure and maintain AWS Site-to-Site VPN and Direct Connect circuits for hybrid connectivity between on-premises data centers and AWS environments.
• Design and enforce AWS Security Group and Network ACL policies as network-layer access controls, aligned with PCI DSS segmentation requirements.
• Manage DNS architecture within AWS using Route 53 for private hosted zones, resolver endpoints, conditional forwarding, and DNS failover across hybrid environments.
• Configure and manage AWS NAT Gateways, Elastic IPs, and Elastic Load Balancers (ALB/NLB) for workload exposure and traffic routing.
• Maintain AWS network connectivity for partner data and compute workloads migrated into cloud environments, including GDPR and data sovereignty considerations.
AWS Security & Compliance
• Implement and maintain AWS security controls at the network layer including Security Groups, NACLs, VPC Flow Logs, and WAF rulesets on CloudFront and ALB.
• Enable and manage AWS CloudTrail across accounts to ensure comprehensive API activity logging; integrate with centralized SIEM for alerting and audit evidence.
• Configure and maintain AWS GuardDuty for threat detection; triage findings and drive remediation in coordination with the security team.

• Administer AWS IAM policies, roles, and permission boundaries as they relate to network resource access; enforce least-privilege principles across VPC, Direct Connect, and Transit Gateway configurations.
• Use AWS Config rules and AWS Organizations SCPs to enforce network security standards and detect drift across multi-account environments.
Monitoring, Observability & Automation
• Monitor AWS network health using VPC Flow Logs, CloudWatch metrics and alarms, Transit Gateway Network Manager, and Reachability Analyzer.
• Build and maintain CloudWatch dashboards and alarms for network throughput, latency, NAT gateway utilization, VPN tunnel status, and Direct Connect metrics.
• Evaluate, deploy, and operationalize FOSS tools as replacements for commercial products where appropriate (e.g., Oxidized, NetBox)
• Contribute to Infrastructure as Code for network resources using automation; enforce configuration consistency across environments.
• Maintain comprehensive documentation for network topology, configurations, and operational runbooks; support PCI DSS and SOC 1 Type 2 audit evidence collection.
• Participate in on-call rotation and be available for after-hours work including unscheduled incidents.
• Travel to domestic data center and office locations as needed to support deployments or incidents.
