Job description

Dark Wolf is seeking a Senior Cybersecurity Engineer to join a collaborative team to develop, manage, and maintain the security posture of cloud‑based information systems with a focus on SIEM validation, continuous exposure management, and continuous Authorization to Operate (cATO) support. The successful candidate will support the team and customers through advanced technical evaluations, detection engineering, and cloud architecture security, ensuring high standards of security and compliance. This position is based out of the Washington DC Metro area with a hybrid schedule opportunity.

Responsibilities

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

Required Qualifications

• Bachelor’s Degree in Computer Science, Cybersecurity, or a related field.
• 10+ years of relevant Cybersecurity experience focusing on SIEM validation, tuning, behavioral analytics (integrated with AWS infrastructure), continuous exposure management, and cATO support.
• Hands‑on knowledge and experience with AWS and Splunk.
• Active IAT Level 2 certification (e.g., Security+ CE, SSCP, CCNA Security), with a strong preference for higher‑level certifications.
• Experience conducting technical evaluations of information systems design, containerized applications, and cloud architecture.
• Experience using automated tools to monitor cloud environments for configuration drift against Security Requirements Guides.
• Ability to use prior experience and knowledge to address new situations, especially during client interactions.
• Ability to communicate technical subjects using clear, concise, non‑technical language, including strong written communication, provision of written feedback on documents, and preparation of briefings.
• US Citizenship and an active Top Secret security clearance.

Desired Qualifications

• IAT Level 3 or higher certifications (e.g., CISSP, CASP+, CISM, GSLC).
• Advanced technical certifications relevant to the environment (e.g., AWS Certified Security – Specialty, Splunk Enterprise Security Certified Admin).
• Hands‑on experience using AI‑assisted RMF tools to ingest Infrastructure‑as‑Code (e.g., Terraform) for automated compliance mapping.
• Deep understanding of container security (e.g., Kubernetes, Docker) and securing DevSecOps pipelines.
• Experience giving technical guidance to cloud engineers and system administrators.

The salary range for this position is estimated to be between $155,000.00 - $180,000.00, commensurate with experience and technical skillset. Candidates at a Principal or Senior Principal (or equivalent) level will be considered.
