This position will be based out of the Washington DC Metro area with a hybrid schedule opportunity.

Responsibilities include but are not limited to:

• Conducting technical evaluations of information systems design, containerized applications, and cloud architecture, ensuring security and operational requirements map directly into the System/Enterprise Architecture.
• Validating the efficacy of log ingestion across IaaS, OS, and application layers (including AWS CloudTrail, VPC Flow Logs, and GuardDuty alerts).
• Developing, testing, and deploying custom detection engineering rulesets within the SIEM.
• Utilizing automated cloud security posture assessment tools to continuously monitor the AWS environment for configuration drift, ensuring strict adherence to the provided Security Requirements Guide.
• Leveraging AI-assisted RMF tools to ingest infrastructure-as-code (e.g., Terraform) and system documentation to rapidly identify compliance gaps, accelerating the cATO process.
• Supporting continuous exposure management and cATO workflows to maintain real-time system authorization.
• Coordinating proper security control implementation and detection tuning with system administrators and cloud engineers.
