Role: Agentic AI Developer (Python) - Vertex AI RAG Graph/Vector Datastores

Location: Berkley Heights NJ (5 Days Onsite)

Duration: Long term Contract

Employment Type: Must work on Next Gen Software Solutions LLCs W2

Role summary

Were 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. Youll own end-to-end delivery: ingestion retrieval agent orchestration evaluation deployment.

What youll 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 GCP 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/) or platform enablement (internal developer tooling).
