The Data Science team at Nextdoor is part of the Data org, which also includes Business Intelligence and Data Engineering.

The Data Science group is made up of people from a diverse set of backgrounds and perspectives, trained in fields as wide-ranging as psychology, geology, physics, and statistics. Data Scientists at Nextdoor serve as the mathematical decision scientists for their product group and play an active and collaborative role in improving the product.
