• Automate SAST, DAST, SCA, and secrets scanning as required pipeline stages, with policy-based gates that prevent insecure builds from promotion.
• Integrate container scanning, registry admission controls, and runtime protection using Aqua Security to enforce Kubernetes and CIS benchmarks.
• Scan Terraform and Kubernetes configurations for security issues and remediate findings before deployment.

App Enablement and Developer Self-Service

• Build reusable Terraform modules and GitLab templates that allow application teams to provision namespaces, environments, and supporting AWS resources without platform-team tickets.
• Design self-service onboarding workflows covering repository creation, CI/CD setup, RBAC and quotas, and security-gate enrollment.Publish standardized GitLab pipeline templates and golden-path patterns so security, compliance, and observability are built in automatically.
• Maintain onboarding documentation and module catalogs, and use adoption and onboarding metrics to identify and remove friction.

Security, Compliance, and Identity

• Implement and enforce STIG, CIS, and organizational security requirements across pipelines, platforms, and workloads.
• Design and manage AWS and Kubernetes IAM, including RBAC, admission controls, pod security, network policies, and secrets management using AWS KMS and Secrets Manager.
• Support vulnerability management, ATO and accreditation activities, audits, and continuous compliance reporting across FedRAMP and DoD environments.

Observability, Incident Response, and Reliability

• Operate observability platforms including Datadog, Dynatrace, Splunk, OpenTelemetry, CloudWatch, and OpenSearch for metrics, logs, traces, dashboards, and alerting.
• Lead critical incident response, including real-time diagnostics, stakeholder and executive communication, root-cause analysis, and corrective actions through resolution.
• Facilitate cross-team root-cause reviews and drive resulting reliability improvements through implementation.

Leadership and Delivery

• Lead transformation initiatives across AI, advanced analytics, and emerging technologies, translating strategy into actionable engineering roadmaps and technical responses to RFIs.
• Establish engineering standards, review architecture, and mentor engineers across DevSecOps, cloud, security, and automation.
