AI Engineer

This role builds LLM and document-intelligence capabilities on a greenfield data and AI platform in a high-trust federal environment. Work is hands-on, scoped to a near-term product demonstration, and built to migrate - documented, portable, and transferred to the internal team. Engagement is 1 year with option to extend. Active T5/SSBI clearance required., * Develop RAG and document-processing pipelines on a cloud-based lakehouse platform (Databricks), including OCR, data ingestion, chunking, and retrieval.

• Build workflows for LLM-based summarization, information extraction, and evidence-grounded text generation with source attribution.
• Generate synthetic document corpora that capture fidelity and quality variation for meaningful analysis.
• Establish evaluation frameworks for retrieval accuracy, groundedness, hallucination checks, and structured output validation.
• Document processes, package deliverables, and track models and artifacts using tools like MLflow.
• Collaborate with internal teams to transfer knowledge and facilitate operational deployment.

U.S. citizenship and active T5/SSBI federally adjudicated clearance required.

Document processing at scale: OCR, layout-aware parsing, chunking tradeoffs, poor-quality source handling. Local/self-hosted LLM serving - vLLM, TGI, Ollama, llama.cpp, or equivalent - including running open-weight models in an isolated or air-gapped environment without reliance on external API endpoints. Structured extraction and grounded generation with source attribution. LLM evaluation methodology - you can explain how you measured correctness and what the evaluation missed. Privacy-preserving synthetic data generation from CUI, PII, or comparably restricted source data, with an understanding of re-identification risk. Strong Python.

Preferred Qualifications RAG built inside a government or FedRAMP-authorized environment (Azure OpenAI in GCC High, AWS GovCloud, Bedrock within an authorized boundary). Direct experience with FedRAMP Moderate, NIST 800-171, CMMC L2, or CUI handling. Databricks Vector Search, Mosaic AI Agent Framework and Agent Evaluation, Asset Bundles, MLflow. Unity Catalog governance. H2O (h2oGPTe, Driverless AI). Soft Skills Self-directed execution against a fixed milestone with minimal oversight. Honest reporting of model behavior - comfortable saying what an evaluation does and does not establish. Collaboration across technical and non-technical teams.
