Lead Data Scientist

Doodle is quickly becoming the core internet utility for scheduling used every day. We enable great meetings because people can do amazing things when working together. Today, Doodle’s products reach more than 28 million users per month. We make it our mission to find the optimal point in time for 8 business people to schedule this super important meeting.

We are working on reaching the next higher orbit by bringing ML to the core of our offering.

  • How much time did Doodle save for every user?
  • What hints can we give to users to optimize their scheduling?
