Lead Backend Developer - Elixir



Software Engineering
Paris, France
Posted on Thursday, April 28, 2022


PandaScore is the esports data provider. We collect real-time data about competitive matches on video games such as League of Legends, CS:GO or Rocket League. Then, we deliver it in real-time as odds & statistics through a REST API and Websockets to the e-sports ecosystem. We currently work with worldwide media, professional teams, and score apps among others to enable the growth of their business with our data!

To collect real-time data from e-sports, PandaScore extracts raw data from live video feeds (Twitch, Youtube Live, …) using a Computer Vision & Deep Learning based software architecture.

PandaScore has been expanding to e-sports betting market for a year now to become the first data provider in one of the most developed markets in the industry.

Why are we doing all this? 🤷‍

Sports is huge, no spoiler there. More recently video games have changed the way we experience entertainment (through streaming, easy matchmaking, and so on) and are reaching the same standard as traditional sports. E-sports is experiencing the same evolution as traditional sports has gone through over past decades, but in just a few years. The growth is truly incredible.

At PandaScore we want to help the growth of the industry by providing data and odds to businesses. We want to have the most reliable and accurate data so products can be built in e-sport with the same, if not better, experience as sports. Our customers are using our data in an automatic and real-time way. This means that if we fail in any way there will be a big impact in a few milliseconds. As such, building robust products is key.

We also strongly believe that our combination of AI and Computer Vision can one day make a huge impact not just on e-sports, but on traditional sports as well. We are not closing any doors.
