Responsibilities

•Design and implement CDS components enforcing strict data flow control and security policies across classified/unclassified domains.

• Develop secure communication features across OSI Layers 2–7, including packet filtering, protocol validation, and deep content inspection.

•Architect and maintain secure messaging systems with emphasis on integrity, confidentiality, and controlled data release.

•Deploy and harden CDS services using Docker and Kubernetes/Docker Swarm, with RBAC and secure container lifecycle management.

•Achieve low-latency, high-throughput data transfer while maintaining compliance with security frameworks (e.g., Common Criteria, NIST).

•Implement secure coding practices, encryption (TLS/mTLS), and audit mechanisms aligned with cybersecurity standards.

•Lead technical discussions and drive architectural decisions in collaboration with security architects, compliance teams, and government stakeholders to meet accreditation requirements.

Requirements

•8+ years in software engineering, with 2–3+ years in secure networked systems or CDS environments.

•A self-driven engineer who is comfortable taking ownership and providing technical guidance to the team.

•Proficiency in C/C++, Go, or Rust for performance-critical components.

•Proficiency in one or more of: Java (Spring/Spring Boot), C#/.NET, Node.js (TypeScript), or Python for application-layer work.
