• Review cloud vulnerability and compliance scan results within 5 business days of scan completion; drive critical and high findings to closure within Department and BOD timelines; provide closure evidence to ISSOs for POA&M management (RMF Step 6).
• Perform Security Impact Analysis on cloud infrastructure and configuration changes submitted through CA change management; participate in CCB/ECM.
• Demonstrate cloud control implementations during Security Control Review Meetings and provide screenshots, logs, and configuration evidence to the SCA (RMF Step 4).
• Support infrastructure-as-code and container image security checks in DevSecOps pipelines and ensure results are captured as SSP evidence (RMF Step 3).
• Coordinate with cloud system operations teams and CSPs to validate remediation and maintain the accredited security posture of cloud systems.

• Working knowledge of NIST SP 800-53 Rev. 5 control implementation in cloud environments and FedRAMP inheritance models.
• Active, final SECRET security clearance; U.S. citizenship.
• DoD 8140/8570 IAT Level III or IAM Level II baseline certification (e.g., CISSP, CASP+, CCSP, CISM) or ability to obtain within 6 months.
• Experience producing authorization evidence (diagrams, configuration exports, scan reports) for ISSOs and assessors.

Preferred Qualifications

• CCSP, AWS Certified Security – Specialty, or Azure Security Engineer Associate; Wiz certification.
• Department of State or other federal civilian cloud authorization experience.
• Experience with Terraform/CloudFormation security, Kubernetes/container security, and CI/CD pipeline integration.
• Experience with cryptographic key management services (AWS KMS, Azure Key Vault, HSMs) and FIPS 140-2/140-3 validated modules.

Technical Skills

• Wiz (or comparable CNAPP), AWS/Azure native security services, IAM, logging/monitoring, KMS/Key Vault.
• Tenable integration for hybrid boundaries; STIG/CIS benchmarks for cloud OS and services.
• Infrastructure-as-code (Terraform, CloudFormation, Bicep), containers/Kubernetes, CI/CD tooling.
• NIST SP 800-53 Rev. 5, 800-144/145/210 cloud guidance, FedRAMP, zero-trust architecture (NIST SP 800-207).
• Scripting (Python, PowerShell, Bash) and REST API automation; Visio diagramming.

Education

• Bachelor's degree in Computer Science, Information Technology, Cybersecurity, or a related field, or an additional four (4) years of directly relevant experience in lieu of degree.

Remote/Hybrid/On-site and any other relevant work-environment requirement

• Remote. Duties are performed remotely; the selected candidate must reside within the National Capital Region (NCR).
