Strategic Business Systems (SBS) is expanding our team to support a high-priority, mission-critical national security program. We are building out secure data movement capabilities across classification boundaries and are looking for engineers who understand how to design and implement low-to-high data transfer solutions in controlled environments.

This role is focused on developing and supporting Cross Domain Solutions (CDS), including AWS data diode architectures, to enable secure, compliant movement of data between networks of differing classification levels. You’ll play a key role in enabling mission systems-both on-prem and in AWS classified environments-to share data safely while maintaining strict security controls. What You’ll Be Doing

• Design and implement low-to-high data pipelines across classification boundaries
• Support and integrate Cross Domain Solutions (CDS), including data diodes and guard technologies
• Build secure data ingestion, validation, and transfer mechanisms into AWS environments and on-prem systems
• Develop and enforce data filtering, formatting, and content inspection rules
• Integrate CDS pipelines with AWS services, HPC systems, and enterprise applications
• Support deployment of pipelines into AWS classified regions (e.g., GovCloud or other secure environments)
• Implement logging, monitoring, and audit capabilities for cross-domain transfers
• Support testing, accreditation, and operational deployment of CDS capabilities, * Experience with Radiant Mercury, Owl Cyber Defense, Everfox, or similar CDS tools
• Familiarity with Infrastructure as Code (Terraform, CloudFormation) in secure environments
• Experience supporting ATO or compliance-driven deployments
