Job Summary:

EveryMatrix is looking for a Backend Developer to join our SportsEngine team in Bucharest.

Company Intro:

EveryMatrix is a leading B2B SaaS provider delivering iGaming software, content and services. We provide casino, sports betting, platform and payments, and affiliate management to 200 customers worldwide.

Team Description:

The Sports Engine is the beating heart of the whole OddsMatrix system: all the betting odds transactions are flowing through the Sports Engine. It is composed of several distributed modules which support three main functions:  data collection, data processing, data publication.

Sports Engine has soft real-time constraints: end-to-end time for each transaction must be less than 1 second.

Sports Engine has availability constraints: high availability is a must and we are striving for up-time measured in months. If the Sports Engine is down, all the other components of the OddsMatrix system become unusable.

Sports Engine is an evolving system: We must keep the pace with an ever-increasing number of betting odds. In the last couple of years, the number of odds doubled, and we are preparing for a similar increase in the future. Related, on peaks, we reach several thousand transactions per second.
