Format data appropriately for the chosen LLM and training pipeline.
• Model Training & Fine-Tuning:
  Design, train, and fine-tune various LLMs on extensive healthcare data to solve specific clinical or operational problems. Set up and manage the training environment, including GPU instances and required software. Train and fine-tune pre-trained LLMs on the custom dataset to achieve specific goals. Experiment with and fine-tune hyperparameters such as learning rate, batch size, and training epochs to optimize model performance.
  
  Integration of structured + unstructured data (multi‑modal/multi‑input models).
• Model Evaluation & Optimization:
  Evaluate model performance using appropriate metrics, identify areas for improvement, and implement optimization strategies.
• Pipeline Development:
  Develop and maintain robust and scalable data and ML pipelines for model training, inference, and deployment.
• Collaboration:
  
  Work closely with data scientists, clinicians, and software engineers to understand requirements, integrate models into production systems, and ensure data privacy and security compliance.
• Research & Development:
  Stay up-to-date with the latest advancements in machine learning and healthcare AI, and explore new technologies and methodologies to enhance our solutions.
• Documentation:
  Maintain clear and comprehensive documentation of models, data pipelines, and experimental results.

• Education:
  
  Bachelor's or Master's degree in Computer Science, Machine Learning, Artificial Intelligence, or a related quantitative field.
• Experience:
  
  5+ years of experience in Machine Learning Engineering or a similar role.
• Proven experience with large-scale data preprocessing, LLM/model training, and fine-tuning.
• Experience with distributed training (PyTorch Distributed, Deep Speed, Ray, Hugging Face Accelerate).
• Experience with GPU/TPU optimization, memory management for large language models.
• Experience working with healthcare data is highly desirable.
• Technical
  
  Skills:
  • Proficiency in Python and relevant ML libraries (e.g., Tensor Flow, PyTorch, Scikit-learn, Pandas, Num Py).
  • Strong understanding of various machine learning algorithms, Large Language Models, and deep learning architectures.
  • Experience with cloud platforms (e.g., GCP, AWS) and distributed computing frameworks (e.g., Spark) is a plus.
  • Familiarity with MLOps practices and tools.
• Soft Skills:
  • Excellent problem-solving and analytical skills.
