Senior Software Engineer

Description

The company is a sports technology business working where sports, media and betting meet. It serves more than 1,700 sports federations, media outlets, betting operators and consumer platforms in 120+ countries.

The Sports Media Team is hiring a Senior Software Engineer in Warsaw, Poland. The team builds cloud-native solutions and works closely with colleagues across functions.

The team holds exclusive data rights for MLB, NBA, NHL and NASCAR, which gives it direct access to in-stadium data, including player and optical tracking. For leagues such as the NFL, NCAA and global sports, it builds tools for a large scouting network.

Its systems deliver live game data to partners such as Apple, Google, Amazon, Facebook, The Score and Bleacher Report, handling billions of API calls each month. Its analytics and broadcast tools support Fox Sports, Bally Sports, CBS Sports, NBC Sports and others during major events, from the World Series to the Super Bowl.

The hiring process has four stages: a short call with a Talent Acquisition Partner, a brief take-home technical task, a technical interview that goes through your solution with the technical team and Hiring Manager, and a final step with feedback and a possible offer. An onsite visit to meet the local team may be added if needed.
