It’s Time For A Change… Your Future Evolves Here

Evolent Health has a bold mission to change the health of the nation by changing the way health care is delivered. Our pursuit of this mission is the driving force that brings us to work each day. We believe in embracing new ideas, challenging ourselves and failing forward. We respect and celebrate individual talents and team wins. We have fun while working hard and Evolenteers often make a difference in everything from scrubs to jeans.

Are we growing? Absolutely—about 50% growth from 2015 through late 2019. Are we recognized? Definitely. Evolent was the first organization ever to receive NCQA’s Population Health Program Accreditation, and is consistently recognized as one of the Becker’s Healthcare 150 Top Places to Work. We recognize employees that live our values, give back to our communities each year, and are champions for bringing our whole selves to work each day. If you’re looking for a place where your work can be personally and professionally rewarding, don’t just join a company with a mission. Join a mission with a company behind it.

This position is for the Chicago location.


What You’ll Be Doing:

The Associate Director Data Scientist 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 part of Data Science and Artificial Intelligence team you will be working primarily on unstructured text data to build machine learning models for information retrieval applications.  These applications include but are not limited to optical character recognition, understanding the contents of the medical documents using natural language processing, 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. The results will be used dually for real-time operational processes with both automated and human-based decision making as well as contribute to reducing 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.  

The Sr. Scientist will have the opportunity to build a team, shape team culture and operating norms as a result of the fast-paced nature of a new, high-growth organization.
