Software Technical Lead

About KAST

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.

• Strong full-stack capabilities including modern front-end frameworks (React.js, Next.js).
• Experience in blockchain development, smart contracts, DApps, and Web3 technologies is highly valued.
• Extensive expertise with cloud platforms (AWS, GCP), including architecture design, cost optimization, and multi-region deployments.
• Expert-level understanding of distributed systems, microservices patterns, event-driven architecture, and system design at scale.
• Deep experience with database architecture, sharding, replication, and performance optimization across SQL and NoSQL systems.
• Proven track record in establishing CI/CD best practices, release engineering, and deployment strategies (blue-green, canary, feature flags).
• Demonstrated ability to lead, grow, and retain engineering talent.
• Expert knowledge of security architecture, compliance requirements, and secure development lifecycle.
• Strong experience driving Agile transformation and optimizing team delivery processes.
