Your Future Evolves Here

Position summary
 

The Data Scientist, NLP will support building of AI products in Agile fashion that empower healthcare payers, providers and members to quickly process medical data to making informed decisions and overall reduce health care costs. As a research scientist/engineer and part of the Data Science and Artificial Intelligence team, you will be working primarily on unstructured text data to build machine learning models for information retrieval/processing applications.  These applications include but are not limited to optical character recognition, understanding the contents of the medical documents using natural language processing with help of large language models, and integrating processes into the overall AI pipeline to mine healthcare and medical information with high recall and other relevant metrics. We ingest claims, medical charts, etc. from providers containing unstructured data which will be transformed into structured data to support automated entry into our storage layers for downstream applications and automated assessment against medical policies. The results will be used dually for real-time operational processes with both automated and augmented human-based decision making (i.e., copilot tools) to reduce healthcare administrative costs. We work with all major cloud and big data vendors offerings including but not limited to (Azure, AWS, Google, IBM, etc.) to achieve AI goals in healthcare and support Evolent business.
