Executive 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.

Your mission: build a best-in-class fiat payments platform that integrates PSPs, bank rails, and real-time networks, while orchestrating them intelligently for resilience, compliance, and user experience.

• Define and own the product roadmap for KAST’s fiat payments platform.
• Partner with engineering to design event-driven, reliable, ledger-safe services for deposits, withdrawals, and payouts.
• Integrate and optimize PSPs, banks, and real-time payment networks (e.g., PIX, UPI, Faster Payments).
• Balance cost, approval rates, and resilience with smart routing and failover strategies.
• Work with Compliance and Ops to embed KYC/AML and regulatory controls directly into the payment flows.
• Set and track KPIs: success = rapid, seamless onboarding, near-zero payment failures, and instant reconciliation.

• 10-12+ years in product management, with at least 5+ in payments, PSPs, or banking rails.
• Proven track record building core payment infrastructure or orchestration platforms.
• Deep knowledge of PSPs, real-time rails, settlement, reconciliation, and risk/fraud controls.
• Experience working closely with engineers on API-first, event-driven, cloud-native systems.
• Entrepreneurial mindset: ruthless prioritization, bias to ship, and ability to balance speed with compliance.

• Build the payments brain behind a global, stablecoin-first challenger bank.
• High ownership, zero bureaucracy, and direct impact.
• Work with a world-class team.
• Competitive comp + meaningful equity.
• Join a no-BS, high-energy team on track to be the next unicorn.
