Full description

EngageCraft is a leading provider of innovative digital fan engagement solutions to sports federations, leagues, and clubs, and media and betting companies.

We are trusted by many of the world’s largest sports organizations including UEFA, FIFA, Major League Soccer, DFL Bundesliga, European Tour Golf, ATP Tennis, and others to influence, innovate, develop, and maintain their digital fan engagement solutions.

We are a small (but growing) international team that fosters a collaborative, fun, dynamic and rewarding environment that encourages entrepreneurship, creative thinking and innovative problem solving.

As a result of a new strategic initiative, we are shortly about to launch a SaaS-based, interactive engagement platform that enables digital and social teams of sports organizations to create and publish, premium, interactive fan engagement experiences at speed and at scale.

We are flexible to accommodate remote / home workers from the UK.

  • Implementing code splitting with Webpack to improve mobile performance.
  • Proficient understanding of cross-browser compatibility issues and ways to work around them.
