Introduction

Our data science team harnesses big data, natural language processing, and machine learning to help create next-generation products for Optimizely’s Experimentation, CMS, e-commerce, and data platforms.

This team emerged as a result of the acquisition of two start-ups (Peerius and Idio) that provided personalization products for e-commerce and content. Over the past years, the consolidated company has improved customers' lives such as Intel, HP, Fitch Ratings, Sainsbury’s, and many other brands. Episerver’s acquisition of Optimizely has paved the way for interactions between data-driven experimentation and AI.

This role will work within a team whose primary focus lies in the following areas: Natural Language Processing (NLP), Machine Learning (ML), and Recommendation Systems (RS). Our stack employs a variety of technologies, including (i) code written in Python & Scala, (ii) data pipelines using Spark, Luigi, Docker, Kubernetes, and Terraform, (iii) prototyping deep learning and classic ML solutions using Gensim, PyTorch, TensorFlow, and Scikit-learn.

The team is remotely located within CET +/- 1 hour and works Monday through Friday.
