Data & ML Engineer
You will build the data and model layer for an AI-enabled decision-support system in an accredited environment. You will ingest and transform structured, semi-structured, and unstructured data, resolve records against a shared data model, develop calibrated relevance models, implement retrieval and grounded generation, and package, serve, version, and monitor models and pipelines. You will also establish provenance, auditability, validation, and secure release practices.

- Design and maintain graphs of entities, records, and typed relationships
- Implement probabilistic matching, candidate generation, scoring, clustering, and threshold policies
- Build deduplication and known-record suppression
- Establish provenance for source records
- Develop relevance and priority models
- Design calibration, threshold, and abstention policies
- Perform feature engineering and error analysis
- Implement embeddings, vector storage, retrieval, and grounded generation
- Build secure ingestion, transformation, validation, and publishing pipelines
- Implement quality checks, schema validation, lineage capture, audit logging, and source drift detection
- Package, serve, version, and roll back models
- Maintain audit trails and submit changes through gated release processes
