About HIFI

HIFI is a financial technology company working on how money is represented in software. We build developer tools that allow value to be programmed—with rules, behavior, and logic embedded directly at the asset level. Developers already use our platform and API's to move billions of dollars in production environments around the world. But we view this as the beginning rather than the end.

Founded in 2022, our organization is flat and our team is talent dense. We are in person at our office in Manhattan and are intentional about who we work with.

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.

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.
