The Predictive Analytics Team develops advanced analytical models using AI, most notably machine learning. Our aim is to enable our clients to be one step ahead of their customers.

We encourage our team to dig deep and use world class technologies as they deem fit.

Current Projects and challenges:

  • Inventory Management – predict sales of individual items from stream data. Suggest price changes, and reorders.
  • Predictions – predict every aspect of customer behavior. Most recent projects include predicting next item a customer is going to buy using deep neural networks or predicting optimal time and channel to contact customer.

Our tech stack:

  • We mostly use Python, but there are opportunities to use C++, Java and Go.
  • For data storing and manipulation we’re using Apache Kafka and Spark.
  • Python libraries: Flask, Gensim, Pandas, TensorFlow and Numpy.
  • Google Cloud infrastructure with Kubernetes for container orchestration and GitLab for CI+CD.

What we expect from you:

  • University degree, ideally in Informatics, Artificial Intelligence, Applied Maths, Statistics or related degree
