£45K – £73K Per Annum

Paris

Over the last few years, cryptos and blockchain technologies have introduced a new paradigm (just like the Internet did 25 years ago!). Yet, it is still recent and most of the tools that exist on the market today are only suitable for individuals, not businesses.

Our mission is to support future generations of entrepreneurs, businesses, and organizations (DAOs, Web3, NFTs, Metaverse) in their growth by creating their financial backbone.

We offer an all-in-one app for web3 companies to manage their cryptos daily with cashflow monitoring and reporting tools and the possibility to make payments using cryptos (salaries, invoices, etc) or make exchanges in both crypto and fiat currencies.

We’re a team of happy and passionate crypto-dreamers, convinced that crypto is shaping the world of tomorrow, with backing from world-class US and European investors including Sequoia Capital (Google, Stripe, Youtube, Paypal’s first investor), Y Combinator and eFounders.

What’s so special about engineering at this company?
