Senior Machine Learning Engineer

Overview

As a Senior Machine Learning Engineer on the Triage Intelligence team, you’ll shape end-to-end ML systems that interpret patient requests and support fast, informed triage decisions. You’ll partner with Data Scientists and clinicians to turn experiments into reusable platform components, deploying models at scale with observability and high availability. You’ll balance deep learning, NLP, and traditional methods to solve real clinical problems while driving reusable, cross-team tooling. Join a mission-driven, cross-functional group building a national healthcare platform.
