CoinFLEX people  

From tough but determined and successful beginnings we are forging strong company values for the business, we are building a team of smart, positive, collaborative, productive, ambitious, entrepreneurial, energetic and success oriented people.

This is an opportunity to make a profound difference to an emerging market sector, for example, if you work in the relatively mature equities or fiat FX markets, any work you do will very likely make an intangible difference to the markets or market infrastructure when compared with the gains which are to be made in the relatively infant cryptocurrency market infrastructure

We are doing what we consider to be ground breaking and important work, however we want to have fun along the way so we have an informal yet professional atmosphere where people are encouraged to speak up. We have weekly company wide stand up meetings to aid communication and the overall cohesive growth of the already globally distributed business across Europe and Asia.

We also offer flexible working hours and working from home as necessary.
