Kraken is one of the largest and most successful bitcoin exchanges in the world and we’re growing faster than ever. We’re looking for people who constantly push themselves to think differently and chart exciting new paths in a rapidly growing industry. Kraken is a diverse group of dreamers and doers, we truly believe our success depends on having both in spades. Join us and the movement to change the way the world thinks about money.

Kraken announced the acquisition of Crypto Facilities, a world-leading, regulated cryptocurrency trading platform and index provider in February of this year. The combination of Kraken and Crypto Facilities (now Kraken Futures) creates a global leader in cryptocurrency spot and futures trading. A pioneer in the industry, the firm was the first regulated entity to list futures on Bitcoin, Ethereum, Ripple XRP, Litecoin and Bitcoin Cash. Users value the high integrity, low latency marketplace that Crypto Facilities provides under the regulatory supervision of the UK’s Financial Conduct Authority.
