О проекте

We began with the idea of helping online shops convert more existing visitors into happy customers. We started with a simple yet challenging approach: determine the purchase probability based on the visitor behavior and show coupons to users with a very low purchase probability. From the beginning, our USP (unique selling point) was and is to work with a transparent A/B performance scheme.
We’ve grown into a company of 20 people since then and our vision is to bring our fully automated, machine learning-based on-site targeting to all touch points along the customer journey.

Our tech stack:
— Akka HTTP, Akka Cluster, Akka Persistence
— Apache Spark, AWS S3
— Docker, MongoDB, AWS CloudWatch, Git
— IntelliJ
— Kanban

Are you passionate about on-site targeting and website personalisation? Are you keen to see your Scala and Akka skills in practise? Would you like to work in an agile, friendly environment with interesting challenges? If you want to work in an environment where you can push things forward, you should join us. From data science to engineering, design and sales, we do things differently. We reward collaboration, evaluating new ideas and taking the lead.
