Java Software Engineer

Got a head full of ideas?


We are looking for a Back-End Developer to join the Sports Engine team.

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.
