Responsibilities

• Secure System Development: Design and implement Cross Domain Solutions components that enforce strict data flow control and security policies across classified/unclassified domains.
• Protocol Handling: Develop and optimize secure communication features across OSI Layers 2–7, including packet filtering, protocol validation, and content inspection.
• Performance & Security Optimization: Achieve low-latency, high-throughput data transfer while maintaining compliance with security frameworks (e.g., Common Criteria, NIST).
• Containerization & Orchestration: Deploy Cross Domain Solutions & Services using Docker and orchestrate with Kubernetes or Docker Swarm, ensuring hardened configurations and RBAC.
• Secure Messaging: Architect and maintain messaging systems using RabbitMQ, Kafka, or Redis, with emphasis on integrity, confidentiality, and controlled release.
• Compliance & Assurance: Implement secure coding practices, encryption (TLS/mTLS), and auditing mechanisms aligned with cybersecurity standards.
• Collaboration: Work closely with security architects, compliance teams, and government stakeholders to meet accreditation requirements.

Technical Expertise

• Networking & Security:
• OSI Layers 2–7, secure protocol handling (TLS/mTLS, IPsec), packet filtering, DPI.
• Network segmentation, VLANs, firewall rules, and zero-trust principles.
• Secure Messaging:
• Encryption, authentication, and integrity checks on messaging systems.
• Message filtering and sanitization for cross-domain compliance.
• Container Security:
• Hardened Docker/Kubernetes deployments, RBAC, Pod Security Policies, image scanning.
• Performance & Reliability:
• Low-latency design, fault-tolerant architectures, and secure failover strategies.
• Compliance & Auditing:
• Logging, monitoring, and evidence collection for security accreditation.

Qualifications

Experience:

• 5–8+ years in software engineering, preferably with 2–3+ years in secure networked systems or Cross Domain Solutions environments.

Programming:

• Proficiency in one or more of: Java (Spring/Spring Boot), Go, C#/.NET, Node.js (TypeScript/JavaScript), or Python for application components.
• Proficiency in C/C++, Go, or Rust for performance-critical components will be a plus

Cybersecurity Knowledge

• Containers & Cloud: Experience with Kubernetes, Docker, and secure container lifecycle management.
• Messaging Systems: Hands-on with messaging systems such as, but not limited to, RabbitMQ, Kafka, or Redis in secure, high-availability deployments.
• Mindset: Strong security-first approach, attention to detail, and ability to work in regulated environments.
