Nice-to-have * Knowledge graphs for RAG (entity linking, graph traversal + retrieval fusion). * Streaming/messaging (Pub/Sub, Kafka), document pipelines (Document AI), and multilingual retrieval. * Experience with evaluation tooling (RAGAS, TruLens, custom eval harnesses), prompt/version management. * Frontend integration (basic React/Next.js) or platform enablement (internal developer tooling). ## Description We're looking for a strong agentic AI developer who can build and productionize Vertex AI-based RAG systems (Vertex AI Search / Vertex AI RAG patterns), design reliable tool-using agents, and work comfortably with vector databases and graph databases. You'll own end-to-end delivery: ingestion * retrieval * agent orchestration * evaluation * deployment. What you'll do * Design and implement RAG pipelines on Google Cloud / Vertex AI (chunking, embeddings, indexing, retrieval, reranking, grounding). * Build agentic workflows (tool use, planning, reflection/guardrails, structured outputs) using Python-first frameworks. * Integrate agents with Graph DBs (e.g., Neo4j, JanusGraph, Neptune) and Vector DBs (e.g., Vertex Vector Search, Pinecone, Weaviate, Milvus, pgvector). * Create robust data ingestion/ETL from PDFs, docs, webpages, and internal sources; implement metadata strategy and access control. * Define and run evaluation (retrieval metrics, answer quality, hallucination/grounding checks), and improve system quality iteratively. * Ship to production: APIs, monitoring/observability, cost/performance optimization, CI/CD, and security best practices.
