Non Tech Web3 Jobs in United States

KAST is redefining stablecoin banking for global citizens, crypto professionals, Web3-native businesses, and high-inflation markets seeking USD-backed banking. We’re building the world’s first truly global money app including crypto cards, local accounts, and global payouts in a premium product with top acceptance rates.

Backed by leading investors and led by the former APAC CEO of Circle, our team brings experience from Circle, Airwallex, Revolut, Wise, Grab, Zoom, AWS, and top OTC desks. Since July 2024, we’ve scaled from zero to nearly a million users, becoming the go-to card for the crypto community.

By building directly on-chain, we offer what traditional financial rails can’t: instant yield, flexible collateralized lending, and enhanced investment products. Our cards bring stablecoins to life: spend at 100M+ merchants, withdraw at ATMs, and enable new ways to access credit.

Our culture is velocity × excellence. We move fast, obsess over product quality, and aim to outpace legacy players. Our ambition is clear: to build the next generation of financial services and make KAST the #1 stablecoin bank globally.

You will own and scale KAST’s Business Banking product for US-founded, globally operating startups. This role is for a hands-on builder who ships fast, is obsessively customer-focused, works in ambiguity, and delivers outcomes.

At KAST, speed matters more than anything else. Ideas don’t win - execution does. Only results matter.

Join a no-BS, high-energy team solving complex problems in a fast-paced environment. Every role matters, and your work will shape how people move money, manage digital assets, and experience financial products worldwide.
