Assets that live in fragmented systems and manual workflows are moving onto blockchains -systems designed to move and store value more transparently and efficiently.\nWhile this unlocks more open and programmable financial systems, it also introduces significant complexity. For most users, interacting with this new infrastructure is still too difficult.\nFun builds the infrastructure that powers consumer-facing fintech applications - handling onboarding, account access, and money movement so users can interact with blockchain-based systems as seamlessly as they do with traditional finance.\nFor fintech builders, Fun provides a best-in-class onboarding and deposit stack that drives conversion and unlocks user growth. We operate at the intersection of financial infrastructure, complex engineering, and product experience.\nAbout the Role\nWe're looking for a talented Product Engineer (Mid, Senior, Staff) to join our team and help shape the future of crypto payments.

You'll collaborate closely with protocol, backend, and business teams to solve complex challenges and build tools that scale globally to meet the evolving demands of on-chain payments.
