Fullstack Engineer - Monetisation

About Moon Pay Hi , we’re Moon Pay. We’re here to onboard the world to the decentralized economy by making digital money move as universally and effortlessly as the internet. Why?

Because crypto, stable coins and blockchain aren’t just technologies. They’re tools for global financial empowerment. They give people and businesses more control over their money, their digital assets, and their future, opening access to legacy financial systems that have been out of reach for many. What we doMoonPay is a unified payments platform for digital currency. We make it easy for anyone, anywhere, to buy, sell, swap and pay in digital currencies as easy as sending an email.

That simplicity is intentional, our focus is reducing complexity so people can participate confidently, without needing to be crypto experts. We power the entire flow between fiat and crypto end to end, with compliance, identity checks, fraud prevention, and settlement all built in. This end‑to‑end approach reflects how we work internally: with accountability, rigor, and trust built into everything we ship.

This role can be performed remotely from the United Kingdom, Poland, South Africa, Spain, Portugal, or Romania
