This role sits at the intersection of applied AI research and national security, deploying cutting-edge tooling within classified secure enclaves.
Mission Focus:
• Design, develop, and maintain LLM orchestration frameworks that coordinate static analyzers, retrieval-augmented generation (RAG) systems, and automated testing pipelines
• Develop and optimize data preprocessing pipelines to ingest, clean, transform, and vectorize product documentation, source code, and test results for LLM consumption
• Design and implement database solutions to support RAG architectures, artifact storage, audit trails, and metadata management
Technical Proficiency:
• Collaborate with systems engineers to architect and deploy networked AI tools within secure enclaves
• Conduct performance profiling, optimization, and scalability analysis of mission systems
• Support security assessments and Authority to Operate (ATO) processes
• Collaborate closely with technical leadership on system design decisions and roadmap planning
What We're Looking For:
All candidates must meet the following requirements:
• Bachelor's degree plus 5 years (SWE2) or 8 years (SWE3) of relevant experience, or equivalent
• Proficiency in Python, LLM integration, and data engineering
• Experience with static analyzers and RAG frameworks
• Experience with both relational and vector databases
• Familiarity with Agile methodologies, Git, Jira, and Confluence
• Active TS/SCI + Polygraph
Nice to Have:
• Familiarity with Rust
• Experience with Claude Code or OpenAI Codex
• CI/CD pipeline design and maintenance
• Hands-on experience deploying AI tools within classified or air-gapped environments
• Performance profiling and scalability optimization in networked AI systems
About the Mission:
The AI & Emerging Technologies (AI&ET) team is at the forefront of applying artificial intelligence to national security challenges. Our engineers work in a fast-paced, collaborative environment on problems that directly impact mission outcomes. We value intellectual curiosity, technical depth, and a commitment to responsible AI development.
