Principal Product Manager - Cards - Stablecoin Banking

KAST is redefining stablecoin banking for global citizens, crypto professionals, Web3-native businesses, and high-inflation markets hungry for USD-backed banking. Backed by top-tier global investors and led by the ex-APAC CEO of Circle, our leadership team spans Circle, Airwallex, Revolut, Wise, Grab, Zoom, AWS, and leading OTC desks. We’ve scaled from zero to nearly a million users at ridiculous speed.

By building directly on-chain, we deliver what traditional rails can’t: instant yield, flexible collateralized lending, and richer investment products. With a premium user focus and a culture built on velocity × excellence, we’re moving fast to outpace legacy players and build the next generation of financial services.

Cards are at the heart of our value proposition. They’re how users experience stablecoins in the real world - paying at 100M+ merchants globally, withdrawing at ATMs, and accessing new forms of credit. Our ambition is clear: make KAST the #1 crypto card offering globally - the Centurion of crypto, the Centurion for new wealth.

We’re hiring a Principal Product Manager - Cards to own the card product end-to-end. From commercial customer offerings, to detailed scheme integrations, to fraud and compliance controls, you’ll lead the product that makes stablecoins spendable everywhere.

Your mission: integrate card partners today, build our own processing capabilities tomorrow, and design an iconic product that makes stablecoins spendable everywhere. You will build the "Centurion of crypto.
