Build RAG and document-processing pipelines on the Databricks lakehouse - ingestion, OCR of mixed-quality sources, chunking, embedding, and retrieval.Build LLM workflows for summarization, structured extraction, and evidence-grounded generation with source attribution.Generate synthetic document corpora with the fidelity and quality variation needed for meaningful results.Stand up the evaluation harness - retrieval quality, groundedness and hallucination checks, structured-output validity, human-in-the-loop review. Report results in numbers.Package deliverables as jobs and Asset Bundles, tracked in MLflow, and document everything the internal team needs to own the work.Required QualificationsU.S. citizenship and active T5/SSBI federally adjudicated clearance required.[8]+ years building applied ML/AI or data systems, with demonstrated delivery of LLM and RAG systems you personally built - not notebook demos.Hands-on Databricks.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.Government or defense contracting experience.Preferred QualificationsRAG 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).We are an Equal Opportunity Employer committed to a diverse and inclusive workplace.
