Senior Blockchain Engineer (Visa Sponsorship and relocation to the UK offered)

About MoonPay 🌖💸

Hi, we’re MoonPay. We’re here to onboard the world to Web3.

Why? Because we think Web3 is a unique and democratising technology. It gives people back control of their money, digital identity, data, and property like nothing else before it.

What we do

We’re the leading infrastructure company in Web3. This means we offer our partners everything from payment solutions (we call them 'Ramps') to minting software for digital collectibles, like NFTs. And over 20 million people around the world now trust our products — just take a look on Trustpilot.

We’re also big on collaborations. And we've worked on stunts, drops, and partnerships with some of the world's most prestigious and forward-thinking brands.

But that’s not all. We have also built our own consumer app because we wanted to see if we could build a better Web3 account. It’s taken off in a big way, and we're working hard to continually improve it and to strive for perfection.

So whatever your background, we’re sure there’s something for you here. Come help us build the future of Web3 and digital ownership.

Locations Supported 🌍 

This role can be performed remotely from the United Kingdom, Poland, South Africa, Spain, Portugal, or Romania. Alternatively, visa sponsorship and relocation to the UK are available.

Unfortunately we do not offer business to business contracting arrangements.
