Who are we looking for?

As a Data Scientist you will be part of the Data Science Team within the Intelligence and Insights (I&I) department.

The team designs and launches continuous (big) data experiments to support the commercial and technical departments and to drive innovation in the field of advanced analytics. The next step is putting these models in production and making the execution simple, so you don’t have to do it yourself. As a team you are responsible to deliver clear revenue and EBITDA targets.

In your work as a Data scientist at T-Mobile you develop and apply predictive models that have an impact on commercial performance and technical processes within the organization. Important here is your deep knowledge of both data science and telecom.

Analytical capabilities as well as the ability to transform data into actionable insights and discuss these insights with a business unit is essential for this position. Focus on influencing top management, actively steering the organization and complexity will increase along with the seniority of the specific position.

Furthermore, you will be working with multi- departmental teams where you have to be competent in different areas, such as marketing, finance or mobile network technology.

How good is that!

You will work with non-technical customers and technical colleagues. The departments where you will be working with are the end- users of the models (B2C, B2B, Value Brand, Finance or Technology). To make this job a success you should be a result oriented person that is good at problem analysis and is curios to investigate. Furthermore, you should be customer oriented and a team player. 
The person we are looking for has:

  • Master (WO) degree Statistics, AI, Econometrics or Computer Science
  • 2-3 years experience as Data Scientist or in advanced analytics area
  • Experience can be compensated by education and vice versa
  • Ideally, deep knowledge of both data science and telecom (prio on Data ScienceJ)
  • Strong analytical and problem solving skills
  • Knowledge of building and deploying predictive models (using R, Python, KNIME, SQL, machine learning, HIVE, Spark and Git is essential, understanding the rest of Hadoop is preferred).
  • Knowledge of diverse libraries (such as dplyr, h2o, xgboost, caret, scikit-learn)
  • Know how to work with different algorithms (from regression, decision trees, random forest, gradient boosting, deep learning).
  • Entrepreneurial and commercial mindset with motivation to improve and challenge existing methods
