À propos

We are sourcing on behalf of HIFI, which is a financial infrastructure platform for the modern internet. Businesses around the world—from fast-growing fintech startups to global financial institutions—use HIFI to move money across stablecoins, fiat rails, and onchain systems through a single programmable interface. Customers use HIFI to automate payments, orchestrate treasury, power embedded finance products, and launch new global money workflows without needing to build or manage complex banking, blockchain, or compliance infrastructure themselves. Their mission is to make money programmable by default, and to give developers and businesses the tools to move value instantly, globally, and with software-level control. About the Team The HIFI platform team builds the infrastructure, developer experiences, and financial workflows that power stablecoin-native finance at scale. The team designs and maintains the APIs, user-facing tools, and partner integrations that allow customers to create accounts, move money across bank and blockchain rails, and operate compliant global payment systems. We work across the full lifecycle of modern money movement—from account creation and ledgering, to fiat and stablecoin settlement, to global payouts and onchain connectivity. Our customers span fintech platforms, marketplaces, exchanges, neobanks, payroll providers, and tokenized asset platforms operating across the U.S., Europe, Africa, LatAm, and MENA. This is an opportunity to help build one of the fastest-growing segments of financial infrastructure and define how money moves on the internet over the next decade. About the Role We’re looking for a Backend Engineer to help build the critical systems that power HIFI’s global stablecoin payment infrastructure.
