You will work closely with cross-functional teamsto translate business needs into scalable AI systems.

Key Responsibilities1.

Model Development & Optimization

• Develop, fine‑tune, and optimize LLMs, diffusion models, and multimodal models for various use cases.

• Build and optimize RAG (Retrieval-Augmented Generation) workflows.

• Implement prompt engineering and prompt chaining strategies for high‑accuracy outputs.

• Evaluate model performance using industry-standard metrics.

  1. AI System Architecture

• Design end‑to‑end GenAI pipelines including data ingestion, vector stores, embedding models, and model serving.

• Integrate LLMs into applications using APIs, SDKs, and cloud-based ML services.

• Architect scalable systems for inference optimization, caching, and safety/guardrail layers.

  1. Data Engineering & Preprocessing

• Work with structured and unstructured data such as text, images, audio, and documents.

• Generate embeddings, manage vector databases (e.g., Pinecone, Milvus, FAISS).

• Prepare datasets for training, fine-tuning, and evaluation.

  1. Deployment & MLOps

• Deploy AI models using tools like Docker, Kubernetes, MLflow, AWS/GCP/Azure AI services.

• Manage model versioning, monitoring, and CI/CD pipelines.

• Ensure reliability, latency optimization, and cost-efficient serving.
