Product Engineering plays a pivotal role in developing and delivering our consumer-facing applications. Our team processes data from upstream sources, constructs robust data pipelines to ensure information remains current, and transforms this data for downstream use, providing our users with actionable, exportable insights. Our applications serve as gateways to our extensive knowledge base, which includes millions of healthcare professional profiles and their affiliations.

The Product Engineering Digital Health team is responsible for building and scaling the systems that power our Find Care user platform, which consists of multiple interconnected systems including Find Care API and Find Care Flat File Delivery, as well as new systems under development such as Find Care UI and Network Universe. These systems enable customers to search, access, and integrate healthcare data including provider networks, insurance relationships, and price transparency data into their workflows. As we continue to expand into new markets, launch new API versions, and deepen the breadth of data we collect, it is essential that our team grows and scales accordingly to meet these increasing demands
