Knowledge Graph Engineer (AI)

As per company standards‍ Organization- Emplay Analytics Inc Salary (CTC) - As per company standards ‍ Role Overview We are looking for a Graph Expert with strong, demonstrable expertise in graph technologies to join our team. The ideal candidate will have hands-on experience designing, building, and querying knowledge graphs or semantic graphs, working with Neo4j (Cypher, APOC, GDS), and integrating graph databases into AI and data pipelines. This role sits at the intersection of knowledge graph engineering, LLM-powered application development, and cloud-native AI infrastructure. ‍ Key Responsibilities ● Design and build production-grade knowledge graphs and semantic graphs, defining entities, relationships, ontologies, and graph schemas. ● Write, optimise, and maintain Cypher queries; leverage APOC procedures and Graph Data Science (GDS) library for advanced analytics. ● Integrate Neo4j (or Amazon Neptune) into AI and data pipelines alongside vector databases and relational stores. ● Build and maintain Retrieval-Augmented Generation (RAG) pipelines covering document ingestion, chunking, embedding generation, vector search, and LLM grounding. ● Develop LLM-powered applications using Lang Chain - chains, agents, tools, memory modules, and custom retrievers. ● Integrate Amazon Bedrock to invoke foundation models, manage configurations, and embed them into backend pipelines and agentic workflows. ● Design and implement autonomous or semi-autonomous AI agents with tool use, planning, and multi-step reasoning. ● Collaborate on AWS serverless architecture (Lambda, API Gateway, Dynamo DB, S3) to deploy and scale AI components. ● Participate in code reviews, communicate blockers early, and take tasks through to completion with minimal supervision. ● Document technical design decisions, graph schemas, and pipeline architecture clearly for cross-functional audiences. ‍ Core Skills (Required) Knowledge Graph / Semantic Graph Construction ● Experience designing and building knowledge graphs or semantic graphs. ● Understanding of entities, relationships, graph schema design, ontology modelling, and querying graph data. ● Hands-on experience with Neo4j strongly preferred: Cypher query language, graph data modelling, and integrating Neo4j into AI or data pipelines. Graph Databases ● Hands-on experience with graph databases such as Neo4j or Amazon Neptune. ● Understanding of graph storage models, indexing, querying, and when to choose a graph database over relational or document stores. Python ● Strong fundamentals: typing, async/await, decorators, context managers, OOP concepts, and robust error handling. ● Comfortable writing clean, maintainable, production-grade Python code. Amazon Bedrock ● Practical experience invoking foundation models, managing model configurations, and prompt engineering via Amazon Bedrock. ● Experience integrating Bedrock into backend pipelines and agent workflows. RAG Pipelines ● Hands-on experience building Retrieval-Augmented Generation pipelines: document ingestion, chunking strategies, embedding generation, vector search, retrieval, and grounding LLM responses. Lang Chain ● Practical experience building LLM-powered applications with Lang Chain: chains, agents, tools, memory modules, and retrievers. ● Familiarity integrating Lang Chain with external data sources and APIs. Team Collaboration & Ownership ● Comfortable with code reviews, communicating blockers, and discussing technical trade-offs. ● Able to independently investigate unfamiliar problems, close knowledge gaps, and drive tasks to completion. ‍ Preferred Skills Advanced Graph Analytics ● Experience with graph algorithms: shortest path, centrality, community detection, and graph traversal strategies. ● Applying graph-based reasoning to enhance retrieval and contextual grounding in AI systems. Neo4j Ecosystem ● Deep familiarity with Cypher, APOC procedures, Graph Data Science (GDS) library, and integrating Neo4j with Python-based AI pipelines. AWS Services ● Hands-on experience with Lambda, API Gateway, Dynamo DB, and S3. ● Understanding of serverless architecture, IAM roles and permissions, and event-driven patterns. A2A (Agent-to-Agent Communication) ● Understanding of agent-to-agent communication patterns and protocols. ● Experience building multi-agent systems where agents collaborate, delegate tasks, or exchange context. MCP (Model Context Protocol) ● Understanding of MCP as a standard for connecting AI models to tools, data sources, and external systems. ● Experience building or integrating MCP servers/clients into agentic architectures. Vector Databases ● Exposure to vector databases such as Amazon Open Search and Elasticsearch for storing and querying embeddings in RAG workflows. AI Agents & Agentic Workflows ● Experience designing and building autonomous or semi-autonomous AI agents. ● Understanding of agent loops, tool use, memory, planning, and multi-step reasoning patterns. ‍ Application Process You can apply on this job portal, or submit your resume and relevant details to: placement@emplay.net Email subject line: Application – Graph Engineer – Emplay Inc Please include the following in your email: ● Current CTC ● Expected CTC ● Notice period ● Years of relevant experience ● Reason for job change ● Linked In profile link ‍ Open Linkedin Apply View all jobs OUR PRODUCTS Sales Agents Support Agents Procurement Agents People Performance Agents OUR PLATFORM Conversational AI Knowledge AI Generative AI COMPANY About Us Partner with Us Careers Contact Us RESOURCES Resource hub Video Blog Linked In Twitter POLICIES Terms of Use Privacy Policy Security and Compliance Copyright © 2025 Emplay.
