Vector Data Engineer

The Vector Data Engineer designs and implements the embedding and semantic-search infrastructure that connects discovery, translational, and clinical data into AI-ready knowledge representations. This role bridges multi-omics data engineering and machine-learning infrastructure, enabling scientists and agentic tools to discover biological insights through vector-based search and reasoning. Key Responsibilities

• Develop scalable pipelines that convert multi-omics and clinical data (e.g., proteomics, transcriptomics, spatial omics, biomarkers) into vectorized embeddings for AI and semantic retrieval.
• Build and maintain vector databases and hybrid data stores using technologies such as TileDB, Weaviate, or Snowflake Cortex.
• Collaborate with the Data Transformation Engineers to design standardized data formats suitable for embedding generation and cross-modality mapping.
• Integrate metadata, ontology terms, and provenance into vector representations to ensure traceability and governance compliance.
• Partner with the AI/ML Team to deploy embeddings supporting agentic reasoning, semantic similarity, and cross-dataset query.
• Optimize indexing, retrieval, and inference performance across large-scale multi-omics data collections.
• Evaluate and incorporate emerging representation-learning and knowledge-graph techniques to improve data discoverability and model interoperability.

• MS/PhD in Computer Science, Computational Biology, Data Science, or related field.
• 3+ years of experience building or maintaining vector or semantic-retrieval infrastructure.
• Hands-on experience with multi-omics or biomedical data integration (e.g., RNA-seq, proteomics, clinical endpoints).
• Proficiency in Python and frameworks such as LangChain, Transformers, or sentence-embedding models.
• Familiarity with TileDB, Snowflake, Weaviate, FAISS, or other vector/array database systems.
• Understanding of metadata modeling, ontologies (e.g., OBO, UMLS), and FAIR data practices.
• Strong ability to collaborate across solution architecture, data science, and AI/ML teams.

Strategic Impact

• Multi-omics and clinical data assets transformed into interoperable, vectorized embeddings supporting scientific AI applications.
