About the Role
Dynamic started with a simple vision: every app and website will have a wallet. Three years in, that vision is no longer just an idea. It’s happening now. Wallets are no longer just for crypto apps.

The best crypto apps, like Ondo Finance, Story, and Magic Eden already run on Dynamic. Now, the world’s top fintech and HR platforms are integrating wallets and payments through Dynamic, tapping into crypto rails. We are at a pivotal moment as we scale from supporting leading crypto apps to becoming the wallet infrastructure of the internet.
