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 Why SBS SBS supports mission-critical programs where secure data movement is essential. Our teams work at the intersection of cross-domain security and cloud enablement, helping customers move data safely into modern platforms like AWS. You'll be part of a team that: * Solves complex cross-domain and cloud integration challenges * Supports high-visibility national security efforts * Builds real, operational capabilities-not just concepts ## Related Videos - [Tips and Tricks for Working with JSON](https://www.wearedevelopers.com/videos/1229-tips-and-tricks-for-working-with-json) - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [WeAreDevelopers LIVE - CSS is DOOMed](https://www.wearedevelopers.com/videos/1838-wearedevelopers-live-css-is-doomed) - [30 powerful AWS hacks in just 30 minutes: Boost your developer productivity](https://www.wearedevelopers.com/videos/1624-30-powerful-aws-hacks-in-just-30-minutes-boost-your-developer-productivity) - [Introducing JSON Structure](https://www.wearedevelopers.com/videos/100219-introducing-json-structure) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Walking Into The Era of Supply Chain Risks](https://www.wearedevelopers.com/magazine/106-walking-into-the-era-of-supply-chain-risks) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 162: AI careers, MCP, AWS best practices & floppy sweaters](https://www.wearedevelopers.com/magazine/571-dev-digest-162-ai-careers-mcp-aws-best-practices-floppy-sweaters) - [Best Paying Jobs in Technology](https://www.wearedevelopers.com/magazine/256-best-paying-jobs-in-technology)
