The Opportunity:
CACI is looking for an experienced, innovative, and motivated Senior Data Security Engineer to work on Zero Trust (ZT) implementation efforts in support of U.S. Special Operations Command (USSOCOM), in Tampa, FL. This is a Senior-level cyber position on the Enterprise Development, Application and Training (EDAT) contract. The position may include partial telework, but work will primarily take place at the customer site.

In this high-visibility role, you will be responsible for defining the enterprise-wide data taxonomy and formally adopting the NIST Internal Report 8112 metadata schema. You will move the Command beyond simple file tagging to a complex Attribute-Based Access Control (ABAC) model, where access is brokered based on the pedigree, provenance, and verification status of user credentials. You will provide technical direction to the network-specific execution teams, ensuring that the implementation of Microsoft Purview (NIPR), BigID (SIPR), and Kiteworks remains architecturally coherent and aligned with the DoD Zero Trust Strategy.

Responsibilities:

• Enterprise Engineering Strategy:

  • Serve as one of the Technical Authorities for the Data Pillar, defining and executing the high-level engineering tasks for data discovery, classification, and protection across NIPR, SIPR, and Top-Secret networks.

• Metadata & Taxonomy Design:

  • Define and enforce the enterprise data taxonomy and metadata schemas (specifically adhering to NIST 8112) to standardize how "Trust Attributes" (Pedigree, Verifier, Assurance Level) are ingested and utilized for ABAC decisions.

• Cross-Enclave Integration:

  • Ensure architectural consistency between the cloud-native NIPR stack (Microsoft Purview/Sentinel) and the on-premises SIPR/Top Secret stacks (BigID, Kiteworks, NetApp BlueXP), ensuring policy logic remains uniform even when tools differ.

• ABAC & Identity Integration:

  • Design the integration points between the Data Pillar and the ICAM Pillar, defining the requirements for how User Attributes from SailPoint and Entra ID are consumed by Policy Decision Points (PDPs) like Kiteworks and Purview.

• Standards & Compliance:

  • Lead the development of System Design Documents (SDDs) and validate that all architecture aligns with the USSOCOM Zero Trust Reference Architecture and DoD 8140/8570 compliance requirements.

Qualifications:

Required: 

• Must hold a current Top-Secret clearance and be SCI eligible.

• Bachelor’s degree in computer science, Information Systems, Cybersecurity, or related field (Equivalent experience acceptable in lieu of a degree)

• Minimum 7 years of experience in enterprise data security for a DoD organization. Additional years of experience may be used in place of Education requirement.

• DoDM 8570 IAT III: e.g. CISSP-ISSEP (Information Systems Security Engineering Professional) OR CISSP.

• DoD 8140 Compliance.

• Extensive experience acting as an Architect or Lead Engineer for large-scale DoD or Federal enterprise security transformations.

• Deep expertise in Zero Trust Architecture principles, specifically Data Object-Level Protection (DOLP) and Attribute-Based Access Control (ABAC).

• Proven experience designing architectures that utilize Microsoft Purview (Information Protection/DLP) and Digital Rights Management (DRM) technologies (e.g., Kiteworks, Virtru).

• Ability to design security solutions for Disconnected, Degraded, Intermittent, and Limited Bandwidth (DDIL) and air-gapped environments.

Desired:

• DoD 8570 Compliance: IASAE II requirements

• Master’s degree in computer science, Information Systems, Cybersecurity, or related field

• One or more Cloud/Zero Trust Architecture certifications (e.g., CCSP, Microsoft Cybersecurity Architect SC-100).

• Experience with BigID for data discovery and NetApp BlueXP for storage-level classification.

• Knowledge of NIST Internal Report 8112 (Attribute Metadata) and its application to identity-centric security.

• Prior experience supporting USSOCOM mission requirements.

• Strong communication skills with ability to brief senior leadership and interface with s
