• Implement safety, guardrails, fallback patterns and hallucination control strategies

RAG & Knowledge Creation

• Architect and implement retrieval-augmented generation pipelines with embeddings, vector search and metadata filtering

• Work closely with data engineering to build semantic layers, knowledge graphs and ontology aligned datasets

• Fine-tune and adapt LLMs using domain-specific knowledge while ensuring compliance

Model Engineering & MLOps/LLMOps

• Develop and tune ML/LLM models

• Build robust model pipelines for training, evaluation, deployment and monitoring

• Implements LLMOps practices-lineage, versioning, bias/hallucination evaluation, prompt testing and runtime monitoring

Integration and Application Development
