Role We are looking for a Principal GenAI Data Engineer to join our team. This is a Hybrid role based in San Jose, CA or Bellevue, WA (3 days in office), reporting to the Senior Manager, Enterprise AI Data Platform in the IT Data Strategy department. We are seeking an experienced technical leader to drive the design and implementation of enterprise-grade Generative AI data ingestion, knowledge preparation, and platform architectures that enable scalable, production-ready GenAI applications. This role focuses on architecting robust pipelines and platforms for ingesting, processing, governing, and serving structured and unstructured enterprise data for AI/LLM workloads. The ideal candidate combines deep expertise in enterprise data architecture, unstructured data pipelines, GenAI platform engineering, and strong software engineering skills in Python. What you’ll do (Role Expectations) - Architect enterprise-scale GenAI data platforms for ingestion, transformation, enrichment, and serving of structured and unstructured data - Design scalable pipelines for enterprise knowledge ingestion from diverse data sources including documents, SaaS platforms, knowledge bases, collaboration tools, and databases - Define architecture for metadata extraction, chunking, enrichment, embeddings generation, and knowledge preparation workflows - Design AI-ready data models and storage strategies for vector, graph, and hybrid knowledge systems - Architect scalable unstructured data processing pipelines for text, images, PDFs, tables, and multimodal content Who You Are (Success Profile) - You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful. - You act like an owner.
