## Description

BigBear.ai is seeking an AI/ML Data Engineer to architect, build, and operate enterprise-scale AI data platforms enabling vector databases, semantic search, Retrieval-Augmented Generation (RAG), and agentic AI systems. This role will establish the technical and governance foundations for production AI, including data lineage, source attribution, prompt/context traceability, explainability, and evaluation in mission environments.

What you will do

What You'll Do

 * Architect and evolve an enterprise AI data platform enabling vector search, semantic retrieval, RAG, and agentic workflows.
 * Design cloud-native, distributed data systems optimized for performance, scale, security, reliability, and cost.

Establish and implement controls for:

 * Data quality, lineage, provenance/source attribution
 * Prompt + context traceability and auditability
 * Explainability and evaluation of AI outputs
 * Partner across Data Science, ML Engineering, Software, Cybersecurity, and Enterprise Architecture to translate AI requirements into production-grade capabilities.
 * Lead architectural decisions; drive reuse across organizations and eliminate duplication. Implement monitoring/observability/alerting and operational excellence best practices.
 * Mentor engineers and raise engineering standards (design reviews, coding standards, CI/CD discipline).
 * Evaluate emerging AI technologies (vector DBs, retrieval frameworks, evaluation stacks) and recommend adoption paths.
