Responsibilities

• Design, develop, and maintain ML/AI models and pipelines (training, evaluation, deployment, monitoring)
• Build and integrate LLM-based features (RAG pipelines, agents, prompt engineering, fine-tuning) into production applications
• Collaborate with data engineers to ensure clean, well-structured data pipelines for model training and inference
• Optimize model performance for latency, cost, and accuracy in production environments
• Write clean, well-tested, production-grade code (Python primarily; possibly Go/Java depending on stack)
