Backend Engineer · AI Platform

🗨️ About the team

The AI Platform team mainly provides DataOps and ModelOps solutions for developing AI models that a researcher needs. We focus on managing medical image data for Radiology and Oncology; developing automatic data pipelines and a data management platform for governance; and managing data collection, analysis, curation, medical image rendering, and labeling. We have a strong focus on developing highly efficient and advanced user experiences to ensure data quality and annotation quality for developing high accuracy AI models. To facilitate efficient data labeling for high-quality annotations, we implement DevOps, DataOps, and ModelOps pipeline practices among these platforms to allow the annotators and researchers to semi-automatically and iteratively process and label image samples for model training and development. We also convert, optimize, and productize research models for various supported hardware devices to run AI inference in real-time on patient image data.
