Performance Engineer

At Xanadu, we provide services to clients in Europe and in the US.


Our largest client is Matchbook, a sophisticated betting exchange. This uses peer-to-peer betting where customers can choose to either place a bet or take a bet. It’s suitable for all types of bettors from casual punters to professional traders. Matchbook is no ordinary web platform. It has more in common with the New York Stock Exchange than with a bookmaker. It operates at scale. Its API processes over 450 million API requests per day. It manages billions of dollars worth of transactions.


With more regulated markets opening in the US and around the world we face new opportunities for further expansion, leveraging our cutting-edge technology to provide our partners with an extremely performant and dependable exchange system.


At Xanadu you’ll work at a scale which you’ll rarely find anywhere else. The challenges here are big – really big. The people you’ll work with are hungry to tackle them. If this sounds like a challenge too good to ignore, then we want to hear from you.
