Adobe Experience Platform (AEP) enables businesses to deliver the right experience at the right time to their customers. The Segmentation Service is one of the key AEP services, providing the ability to define customer segments and generate target audiences based on real-time customer profiles. Customer segment definitions are sophisticated queries over profile and event data capturing specific attributes or behaviors shared by a subset of users. With the need to perform trillions of audience segment evaluations per day, scalability and efficiency are paramount in segment evaluation. This is a great opportunity for engineers to solve extremely interesting challenges of scale and build core services that are used by all Adobe Digital Experience solutions. As part of building these services, you will work with an exceptionally talented and collaborative team, tackle complex query evaluation challenges, design & implement innovative algorithms and build highly performant services.
