Use Case

Knowledge Graph Q&A

Build graph-powered chatbots using LLMs + Cypher retrieval

Entity Resolution

Link entities across data sources using graph relationships

Recommendation Engine

Graph traversal-based recommendations enriched with semantic search

Document Intelligence

Extract entities from unstructured text and load into Neo4j

• Design, build, and maintain Knowledge Graphs in Neo4j, defining node labels, relationship types, and ontologies for complex domains.
• Develop GraphRAG pipelines, combining graph traversal with LLM-based generation for intelligent question-answering and search.
• Write optimized Cypher queries for data retrieval, pattern matching, and graph analytics.
• Build and manage data ingestion pipelines from structured and unstructured sources into Neo4j using Python.
• Integrate vector databases alongside Neo4j for hybrid semantic + graph search.

• GenAI & LLMs

• Experience with LLM frameworks — LangChain, LlamaIndex, or similar — for building RAG applications.
• Understanding of embedding models, vector search, and semantic similarity.
• Prompt engineering and chaining experience for structured outputs.

• Programming & Data Engineering

• Proficient in Python — data pipelines, API integrations, and scripting.
• Experience with data pipeline tools (Airflow, Prefect, or similar).
• Comfortable with REST APIs and working with JSON/CSV/structured datasets.

• Good to Have

• Cloud experience — AWS (Bedrock, SageMaker) or Azure (OpenAI Service).
• Knowledge of graph analytics — Neo4j GDS library (PageRank, community detection, pathfinding).
• Exposure to streaming platforms like Kafka or Spark for real-time graph ingestion.
• Familiarity with GraphQL or Spring Data Neo4j for application integration.
• Experience with visualization tools — Neo4j Bloom, Gephi, or Linkurious.

• Bachelor's or Master's degree in Computer Science, Data Science, or a related field.
• 3+ years of experience in data engineering, with a focus on graph databases and machine learning.
• Proficiency in Neo4j and Cypher, with a strong understanding of graph data modeling.
• Experience with Python for data ingestion and pipeline development.
• Knowledge of vector databases (Pinecone, Weaviate, FAISS) and their integration with graph databases.

• Qualifications

• Bachelor's or Master's degree in Computer Science, Data Engineering, Information Systems, or a related field.
• 3–5 years of hands-on experience in data engineering, software development, or AI/ML roles.
• At least 1–2 years of direct experience with Neo4j or other graph databases (ArangoDB, Amazon Neptune).
• Neo4j Certified Professional certification is a strong plus.
