Tetrad Digital Integrity (TDI) is a leading-edge cybersecurity firm with a mission to safeguard and protect our customers from increasing threats and vulnerabilities in this digital age.

TDI is looking for an experienced top-secret or secret cleared, Senior Information Systems Security Engineer (ISSE) to provide Risk Management Framework (RMF) support for a Department of Defense (DoD) program operating within Google Cloud Platform (GCP).  This position involves direct support of cloud-based systems with containerized applications and an integrated Generative AI component.

The Sr. ISSE will have a strong work ethic and the ability to deliver in a fast-paced environment.

  • Conduct security architecture reviews and security engineering analysis for cloud-native and containerized workloads hosted in Google Cloud Platform.
  • Evaluate security controls associated with Kubernetes, Docker, and container orchestration platforms within GCP.
  • Assess security risks related to generative AI components, including large language models (LLMs) and AI/ML workloads, ensuring responsible and compliant use.
  • Develop and maintain System Security Plans (SSPs), Security Assessment Reports (SARs), Plan of Action and Milestones (POA&Ms), and related RMF documentation.
  • Perform threat modeling, vulnerability assessments, and risk analysis tailored to cloud environments and AI technologies.
  • Interface with system architects, developers, and DevSecOps teams to integrate security throughout the Software Development Lifecycle (SDLC).
  • Support security control assessments (SCAs) and coordinate with third-party assessors.
  • Monitor, track, and report on security compliance posture through Continuous Monitoring (ConMon) processes.
  • Provide expert guidance on DoD cloud security policies, NIST SP 800-53 controls, CNSS policies, and DoD-specific frameworks such as Cloud Computing SRG and AI-specific guidance.
QUALIFICATIONS:
  • U.S. Citizenship with an active DoD Secret clearance (Top Secret preferred).
  • Bachelor’s degree in Cybersecurity, Computer Science, Information Technology, or related field.
  • 5+ years of cybersecurity experience, with at least 3 years supporting RMF activities for DoD systems.
  • CISSP, CISM, CAP, CCSP, or GCP Professional Cloud Security Engineer.
  • Hands-on experience with Google Cloud Platform (GCP), including IAM, VPC, Kubernetes Engine (GKE), and security-related services.
  • Strong knowledge of containerized environments (e.g., Docker, Kubernetes) and container security best practices.
  • Familiarity with Generative AI technologies, including LLMs and AI/ML security considerations.
  • Deep understanding of NIST SP 800-53, DoD RMF, FedRAMP, and other relevant cybersecurity frameworks.
  • Experience writing and maintaining RMF artifacts such as SSPs, POA&Ms, and SARs.
  • Strong communication skills and ability to collaborate effectively with technical and non-technical stakeholders.
PREFERRED QUALIFICATIONS:
  • Experience with AI/ML security risk assessments in DoD or federal cloud environments.
  • Experience integrating DevSecOps pipelines with RMF compliance processes.
  • Familiarity with automation tools for RMF documentation and control testing (e.g., Xacta, eMASS, OpenRMF).

Your decision to complete the form and your answer will not harm you in any way.
