  • You will be helping to identify possible use and application cases of data science across Deutsche Telekom

  • You are aware of and willing to apply agile methodology (esp. Scrum)
  • Versatile and proactive. You may not be familiar with all the required skills, but if you are motivated and can adapt rapidly, we are happy to help you (e.g., you have extensive knowledge in ML/AI but little in forecasting)

  • You are strong in communication with clients and explaining technical stuff to non-technical people
