• Develop secure, resilient architectures spanning AWS and on-premises infrastructure using defense-in-depth and Zero Trust principles.
• Modernize environment to leverage Infrastructure as Code using technologies such as Terraform.
• Automate security operations, compliance reporting, configuration management, and policy enforcement using APIs, scripting, Dev Sec Ops  tooling, and AI-assisted engineering tools.
• Support security controls and evidence mapping aligned with frameworks such as NIST 800-53/800-171, FedRAMP, and FISMA.
• Evaluate existing security architectures and identify improvements in security, resiliency, scalability, performance, and operational efficiency.

• Troubleshoot complex cloud, network, firewall, and application-connectivity issues.
• Support security incidents, production outages, and root-cause analysis.
• Develop monitoring, logging, alerting, dashboards, runbooks, and engineering standards.
• Perform performance tuning, capacity planning, and security infrastructure lifecycle management.
• Participate in on-call or escalation support as required.
