- Conduct continuous monitoring, log review, and evidence collection to support compliance audits and third-party assessments
- Perform risk assessments and vulnerability management across cloud and on-premises infrastructure in accordance with NIST RMF
- Maintain configuration baselines and enforce hardening standards (DISA STIGs, CIS Benchmarks) across systems and cloud resources
- Maintain and tune SIEM integrations, security logging pipelines, and alerting rules for cloud and network infrastructure
- Manage endpoint detection and response (EDR) and vulnerability scanning tools across the infrastructure fleet
- Build and maintain automation for compliance evidence collection, configuration auditing, and security reporting
- Document security architecture, network diagrams, access control matrices, and
