Role Summary
We are seeking a highly experienced AI/ML Engineer with a strong foundation in knowledge graph engineering and generative AI to design, build, and scale intelligent data pipelines that transform largescale unstructured data into enterprisegrade Knowledge Graphs.
The ideal candidate will have deep experience in ontology modeling, entity resolution, probabilistic pattern matching, and agentic knowledge base enrichment, combined with strong expertise in LLMs/SMLs, finetuning pipelines, and graphbased reasoning systems.
This role involves architecting and delivering productiongrade AI systems that integrate LLMs with knowledge graphs, enabling contextual reasoning, anomaly detection, and intelligent automation at scale.

• Training and finetuning (SFT, PEFT, adapters)
• Evaluation, benchmarking, and deployment
• Apply prompt engineering, RAG, and hybrid LLM + Knowledge Graph (GraphRAG) techniques for contextual intelligence.

Anomaly Detection & Analytics

• Develop anomaly detection systems on top of knowledge graph data at scale.
• Apply graph analytics, embeddings, and ML techniques to detect:
• Semantic inconsistencies
• Behavioral anomalies
• Data quality and relationship drift

Data & ML Engineering

• Generative AI and reasoning models
• Text generation, summarization, and semantic search workflows

Knowledge Graph Technologies

• Strong experience with:
• Neo4j, GraphDB
• RDF, OWL
• Cypher, SPARQL
• Proven ability to implement:
• Entity linking and resolution
• Semantic search
• Relationship mapping and inference

GenAI Frameworks & Tooling

• Experience building GenAI systems using:
• Lang Chain, Lang Graph
• Llama Index
• OpenAI / Azure OpenAI
• Vector databases such as Pinecone and FAISS

MLOps & LLMOps
