MaC VC
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. About the Role We're looking for a BackEnd Engineer to join our growing team at Fun and help architect the backend services that power our web3 payments infrastructure. This role is foundational to the success of our platform and will shape how payments, settlement, and transaction routing are handled across chains and payment providers. You'll be working on high-performance, low-latency systems that support complex use cases like asset conversion, identity and security verification, transaction finality, and decentralized routing - while ensuring fault tolerance, scalability, and compliance across a global user base.
