Software Engineer, Blockchain

HIFI's engineering team builds the payments infrastructure that fintechs and financial institutions use to move money on stablecoin rails. The team owns the APIs, ledger, and on-chain systems behind every payment HIFI processes, and works closely with product and compliance to make sure that infrastructure is reliable, secure, and ready for regulated use. As HIFI's volume grows and more institutions build on our platform, this team will decide how stablecoin payments hold up at the scale and standard that traditional financial infrastructure is held to.

As a Blockchain Engineer at HIFI you will help own on-chain systems day to day. You'll build and maintain the integrations, smart contracts, and wallet infrastructure that connect HIFI's payments products to the chains and stablecoins we support. This is a hands-on role with real ownership: you'll design how funds move and settle on-chain, work with the rest of engineering to connect those flows to our ledger and APIs, and partner with compliance on controls like wallet screening and transaction monitoring. You'll also be the person the team relies on to judge when a new chain or protocol is ready for production use.
