Senior AI Engineer

Design, develop, and deploy machine learning and deep learning models for classification, regression, clustering, forecasting, anomaly detection, and predictive analytics use cases.

- Build and optimize feature engineering pipelines and data preprocessing workflows for structured and unstructured datasets.

- Perform exploratory data analysis (EDA) to identify trends, patterns, and actionable insights from large-scale healthcare and business datasets.

- Develop and evaluate models using appropriate metrics, cross-validation, and experimentation frameworks.

- Implement NLP solutions for text classification, entity extraction, summarization, and information retrieval.

- Design and fine-tune Large Language Models (LLMs) and transformer-based architectures for domain-specific applications.

- Apply transfer learning and prompt engineering techniques to adapt foundation models to business and healthcare use cases.

- Build AI-driven document intelligence solutions using models such as LayoutLM, Donut, and Table Transformers for key-value extraction and document understanding.

- Support MLOps and model deployment, including Docker-based packaging, cloud deployment, monitoring, and performance optimization.

- Collaborate with product, engineering, and business teams to translate business problems into AI/ML and GenAI solutions.

- Research and experiment with emerging AI technologies, including RAG (Retrieval-Augmented Generation), LLM alignment techniques (RLHF, DPO, PPO, KTO), and model optimization methods.
