Job Specifications

Position Summary

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.

Key Responsibilities

Data Preprocessing: Clean, transform, and prepare large, complex healthcare datasets for machine learning model development. This includes handling missing values, outlier detection, feature engineering, and data normalization. Identify, collect, and curate relevant, industry-specific datasets for model retraining. 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

Requirements

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, DeepSpeed, 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., TensorFlow, PyTorch, Scikit-learn, Pandas, NumPy)
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
Strong communication and collaboration abilities
Ability to work independently and as part of a team in a fast-paced environment
