• Configure and optimize the ATO Automation Platform's LLM backends (e.g. GPT-4, Claude Sonnet, Llama) based on customer security requirements and deployment constraints

• Implement and maintain the Retrieval-Augmented Generation (RAG) architecture that powers the ATO Automation Platform's automated compliance documentation

• Develop and manage customer-specific knowledge bases incorporating organizational policies, security guides, and system documentation for AI processing

• Fine-tune LLM parameters and prompt engineering to ensure outputs match organization-specific documentation standards and terminology

• Implement secure data handling procedures for AI processing of potentially sensitive system configurations and security information

• Configure vector databases and enterprise search technologies that support the ATO Automation Platform's compliance knowledge graph

• Monitor AI model performance and accuracy of generated compliance artifacts, implementing continuous improvement processes

• Deploy approved LLM models in restricted environments including air-gapped networks and classified systems

• Deploy and configure open-source Llama model in air-gapped DoD environment for processing IL5 system configurations

• Fine-tune Claude Sonnet prompts to generate control implementation descriptions matching agency-specific SSP format requirements

• Build custom RAG knowledge base incorporating customer's 500+ security policies and standard operating procedures

• Implement data sanitization pipelines to redact classified markings before AI processing

• Optimize vector embedding strategies to improve the ATO Automation Platform's accuracy in mapping code configurations to NIST 800-171 controls
