The role

Cryptio is looking for a junior software engineer interested in working on crypto / finance / accounting related products.

You will initially join our Integrations Squad, where you'll build essential connectors to third-party services like exchanges (Coinbase, Binance…), custodians (BitGo, Fireblocks…) and order execution management systems (Talos, Wyden…).
