Citizenship: U.S. citizen or green card holder/EAD 

Background Investigation: Eligible for public trust clearance- Government background investigation required  

Key Responsibilities:

• Design and maintain data ingestion, transformation, and processing pipelines (ETL/ELT) for AI training, evaluation, retrieval, and operations, including support for data migration and cleansing.
• Curate, validate, and version datasets, and maintain dataset inventories, metadata, lineage, provenance, and ingestion logs.
• Implement automated data-quality checks for duplication, schema changes, completeness, and freshness, and maintain dataset quality scorecards and drift reports.
• Design data models, vector stores, and embedding schemas for Retrieval-Augmented Generation (RAG) knowledge bases, and re-index content when sources change.
• Measure retrieval and model quality against established baselines using metrics such as precision/recall, MRR, NDCG, and context relevance.
• Prepare data-related deliverables, including AI model cards, ML and AI pipeline documentation, RAG/AI Pipeline Evaluation Reports, data dictionaries and embedding schema documentation, and responses to Government data calls.
• Build secure structured-data access for AI applications (e.g., natural-language-to-SQL with query validation and role-based authorization), and support dashboards and operational analytics.
• Monitor data and ML pipelines, troubleshoot failures, and support root-cause analysis, while keeping all data in FedRAMP-authorized cloud regions with FIPS-validated encryption.
• Support Responsible AI practices by preparing representative evaluation datasets, testing AI outputs for bias, accuracy, and hallucination, and documenting results to meet federal AI governance requirements.
• Secure the AI data path, from source datasets and embeddings to prompts and logs, and support AI risk testing such as data poisoning.

• 5+ years of hands-on data engineering or database development experience, including data modeling, SQL, and ETL/ELT pipeline development.
• Strong proficiency in Python and experience with data processing frameworks (e.g., pandas, Spark) and workflow orchestration tools (e.g., Airflow).
• 1+ year of experience preparing data for Generative AI or machine learning, such as embeddings, vector databases, RAG knowledge bases, or training and evaluation datasets.
• Experience implementing data quality, lineage, metadata management, and data governance controls.
• Experience protecting sensitive data (PII), including masking, minimization, and access controls.
• Experience with a major cloud data platform (AWS, Azure, or Google Cloud), Git, and CI/CD tools.
• Must be a U.S. citizen or lawful permanent resident (green card holder).
• Must reside in the Washington, DC metropolitan area and be able to work on-site at Government offices.
• Must be able to obtain and maintain a Public Trust background investigation.

Preferred Qualifications

• Master's degree in a related field and 7+ years of data engineering experience, including support of federal agency programs.
• Experience evaluating retrieval quality and building RAG pipelines with vector stores (e.g., pgvector, OpenSearch).
• Experience with MLOps tooling, including model and dataset versioning, feature stores, or model registries.
• Generative AI, LLM security, or data certification (e.g., Databricks Generative AI Engineer, Snowflake SnowPro, AWS, Microsoft Azure, or Google Cloud).
• An active Public Trust or prior federal background investigation.
