Senior Data Scientist, Tumblr Core Data Science

Tumblr launched in 2007 with the belief that people need a place to say what they want, be who they want, and connect over their interests. We continue to build out Tumblr as a platform for free expression, individuality, and human connection. That’s why we need smart, humble, funny people to keep Tumblr growing.

We are looking for a well-versed data scientist to join our Tumblr core data science team. You will contribute to Tumblr recommender systems, discovery feeds,  targeted push notifications, user-interest profiling and computational advertisement.

Our data infrastructure is built on top of open source big data frameworks such as Apache Spark and Apache, orchestrated by Apache Airflow and with a PHP backend layer.

  • Design and develop effective models, features and algorithms involving user activities and interests, blogs and posts, social graphs, etc. 
  • Define metrics, conduct A/B tests, and oversee statistical measurement of new algorithms and approaches. 

The Data Scientist position might be a good fit if you have:

  • BA/BS degree in Computer Science or a related quantitative field. Master/PhD preferred.
  • Strong background in statistics, machine learning, mining massive datasets.

  • Knowledge on the following areas is considered a plus: computational advertisement, natural language processing, learning to rank, deep learning for collaborative filtering.
  • You are goal driven, humble, and have equal willingness to learn and teach.
