Job Description
At Fun, we’re building the financial infrastructure for internet capital markets.
The systems that power global finance were designed for a different era: slower, fragmented, and constrained by borders. Today, value is digital, global, and moves instantly, but the experience of moving it hasn’t caught up.
Fun offers the highest converting payment solution in the digital asset space – a unified system that enables users to complete any on-chain action using crypto, exchange balances, or fiat from a card or bank account, all in a single, seamless flow.
Our goal is simple: make transacting with any asset feel effortless, anywhere in the world.
