AI Engineer (TS/SCI with Polygraph is REQUIRED)

Aperio Global is hiring AI engineers at multiple experience levels to support its AI & Emerging Technologies mission. The role develops and deploys AI/ML tools, including LLM-based systems, to improve vulnerability identification and mitigation within classified secure enclaves.

Responsibilities:

• Engineers at all levels will work closely with mission stakeholders to capture requirements, aid in structured planning, and improve the certification process by introducing AI/ML tooling
• You will use AI/ML to develop tools and techniques — including fine-tuning Large Language Models (LLMs) — that assist in enhanced vulnerability identification and mitigation capabilities
• 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
• 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
