Senior Data Scientist (m/f/d) with Leadership Responsibility in Part-Time - Remote or Karlsruhe

At Knuddels, we have the goal of making social networks truly social again – moving away from content consumption towards genuine human connection. At Knuddels, everyone should find 3 important people for their real lives.

100,000 members generate millions of events with us daily. Your task: Not just to analyze this data, but to draw the right conclusions from it – and to ensure that data-based insights reach the entire company and lead to concrete improvements.

Why Part-Time? We know there are great Data Science profiles that cannot or do not want to work full-time – be it due to family, further education, self-employment, or simply a life choice. For us, this is not a compromise, but a conscious decision: rather the right person in part-time than the wrong one in full-time.

• Enabling Data-Driven Decisions: You analyze our data, prepare the results understandably, and derive concrete strategic measures from them. You work closely with Product Management, Community Management, and Executive Management – not in an ivory tower, but as an equal sparring partner. You link quantitative analyses with qualitative feedback from our community to enable well-founded decisions. and establish best practices such as code reviews and documentation.
