.

The Machine Learning Engineer will be responsible for the end-to-end development and deployment of large language and machine learning models, with a primary focus on data preprocessing, model training, and fine-tuning using large‑scale healthcare datasets. This role requires a strong understanding of large language models, machine learning principles, data engineering, and experience working with sensitive healthcare data.

• Data Preprocessing:
  Clean, transform, and prepare large, complex healthcare datasets for machine learning model development. Handle missing values, outlier detection, feature engineering, and data normalization. Identify, collect, and curate relevant industry‑specific datasets for model retraining and 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. Experiment with and fine‑tune hyperparameters such as learning rate, batch size, and training epochs to optimize model performance. Integrate structured and 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 (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 (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; strong communication and collaboration abilities; ability to work independently and as part of a team in a fast‑paced environment.
• Work Authorization:
  Must be a US Citizen, Green Card holder, or currently in the US with a valid H1B visa.
