Job Description

Come join a creative team dedicated to improving football performance by combining cutting-edge technology with top football minds!

Kognia Sports Intelligence is seeking a Backend Engineer for our Content Delivery team, responsible for delivering football insights to our users. You will implement exciting new features in our Kotlin/Spring Boot webapp, in addition to playing other roles as a member of an agile team. The salary range is EUR 35-45K, commensurate with experience.

Kognia Sports Intelligence

We are a young Barcelona-based startup funded by football industry leaders including superstar Xavi Hernández. Since opening our office in early 2019 with the founders plus 2 engineers, we have grown to 20+.

Our technology begins with video capture in the stadiums, detects player movements and actions, and delivers insights to coaches and players in the form of video clips with overlay illustrating high-level tactical concepts. In September 2020 we went into production with a closed beta and are currently delivering insights to our first users. We have a backlog of improvements and exciting new features to implement in advance of a major public release for the 2021-2022 football season, and we need your help!

This position is currently remote but applicants must be open to commuting to our office in Sant Joan Despí  (20 minutes from Barcelona center) at some point in the future, when it is safe to do so.
