Agentic AI Lead

Agentic AI Lead (Python) — Vertex AI RAG Graph/Vector Datastores

Berkeley Heights, NJ (5 Days Onsite)

FTE

Senior candidates only with min 10 years of experience

Role summary

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.

Must-have skills

·       Strong Python (clean architecture, async, testing, typing, packaging).

·       Proven experience building RAG solutions (hybrid search, reranking, chunking strategies, embeddings, prompt schema design).

·       Hands-on with Vertex AI and Google Cloud Platform fundamentals (IAM, logging/monitoring, Cloud Run/GKE, storage).

·       Experience with at least one agentic framework (e.g., LangGraph/LangChain, LlamaIndex, Semantic Kernel, AutoGen) and tool/function calling patterns.

·       Solid knowledge of vector search concepts and at least one vector DB in production.

·       Comfortable with graph data modeling and graph querying (Cypher/Gremlin/SPARQL basics).

·       Strong engineering practices: code reviews, testing, telemetry, secure-by-design, reliability mindset.

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).
