Engineering · Madrid · Hybrid Full-stack Engineer (Spain) About Crossmint
Crossmint is the leading enterprise-grade, all-in-one stablecoin and wallet infrastructure platform enabling fintechs and enterprises to integrate stablecoin rails and smart wallets with speed, compliance, and scale.
Backed by Ribbit Capital, Franklin Templeton, NYCA, First Round, and Lightspeed Faction, with $23.6M raised in 2025. Trusted by more than 40,000 clients including global leaders such as MoneyGram, WireX, Toku, and more, Crossmint provides embedded smart wallets, on/offramps, cross-chain stablecoin orchestration, tokenization, and other blockchain primitives through simple, developer-friendly APIs that integrate in minutes and scale to millions of users.
In January 2026, Crossmint secured MiCA authorization from Spain's CNMV, becoming one of a select few stablecoin infrastructure providers fully licensed to operate across all 27 EU member states and held to the same regulatory standards as traditional financial institutions. Crossmint also powers the Republic of the Marshall Islands' first digital UBI program, backs MoneyGram's new stablecoin cross-border experience launching in LATAM, and recently partnered with WireX to expand multichain stablecoin payment infrastructure to non-EVM networks like Stellar.
The future of finance is stablecoin-native. Crossmint makes it easy to get there.
We have offices in Madrid, and we are also open to a full remote setting from Spain.
