Your task – this awaits you in detail

  • As a (Senior) Data Scientist (f/m/d) in this role, you will build and enable our ability to make data-driven decisions, often based on A/B tests.
  • Here are some examples of questions that you will deal with: Do customers who experience a delay in their delivery tend to come back less often? If so, is the difference significant and is the delay even the root cause or does the causality lie in the originating country of the sellers they bought goods from or the types of goods themselves? Do products with free shipping or faster shipping have higher conversion rates? Does this apply to all product segments? And if so, is this a causal effect or is it just a correlation that is grounded in a selection bias?
  • You will have access to vast amounts of data such as time series sales data, natural language unstructured product information, and customer behavioral data to dig in and help uncover relationships to improve our customer experience and business.
  • You will be responsible for finding the best approaches and solutions to solve business challenges, design data sets, and of course, build analytical and machine learning models to answer research questions.
  • You will work closely in a smart and fun team with other data scientists, machine learning engineers, business intelligence analysts, web analytics specialists, and of course closely with product managers and other stakeholders.

Your profile – this is what we expect from you

  • You have a university degree in mathematics, computer science, information systems, or the like.

  • You have proven experience with statistical modeling and causal analysis, ideally in the Python ecosystem. Experiences in related fields such as machine learning, predictive analytics, natural language processing, or deep learning are a plus.

  • Experience with behavioral web analytics data such as from Google Analytics is a plus.

  • You have or would like to work in a business-aware environment, thinking “end-to-end” over just solving a theoretical problem.

  • You are used to finding your way around data sources, including a good knowledge of SQL or SQL-like dialects – ideally with large data sets.

  • You are proficient in the programming language that is the weapon of your choice, ideally Python, and have a good understanding of the respective package ecosystem.

  • You have excellent communication skills, are willing to embrace our company culture and values, and enjoy working in an international, English-speaking team.
