Non Tech Product Manager Jobs in Web3

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 will 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 today’s 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 stablecoin bank globally.

We’re hiring a Principal Product Manager - KAST Pay to own our core banking and payments platform. This is the product that makes deposits seamless, payouts instant, and transfers magical.

Your mission: build a world-class stablecoin banking core – integrating custody, ledgers, and reconciliation – and pair it with payments infrastructure that handles deposits, payouts, and peer-to-peer transfers across fiat and crypto rails.

At KAST, ideas are worth zero. Execution at ridiculous speed is everything. You’ll be expected to ship relentlessly, overcommunicate progress, and make the complex (custody, ledgers, reconciliation) stupid simple.
