Design Web3 Jobs in Australia

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 onchain, we’ll 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 how users experience stablecoins in the real world—paying at 100M+ merchants, withdrawing at ATMs, and accessing new forms of credit. Our ambition is clear: make KAST the #1 stablecoin bank globally.

We’re hiring a Senior UX UI Designer to craft high-conversion mobile experiences across onboarding, cards, payments, savings, and referrals. You’ll work closely with Product, Engineering, and Compliance to ship designs that are simple, fast, and compliant—without compromising on quality.

Your mission: Build an experience that moves as fast as our users and make KAST the category leader. You’ll come forth with initiative ideas on UI and UX which have never been seen before. KAST will be the most intuitive, premium, and addictive stablecoin banking app.

• Own end-to-end design for core journeys (KYC → card activation → first spend).
• Turn complexity (on-chain actions, compliance steps, FX, fees) into simple UX.
• Build and maintain clean, extensible design systems.
• Prototype rapidly (Figma/Proto tools) and validate with users; iterate using analytics.
• Partner with Product & Engineering to scope MVPs, define acceptance criteria, and
• Ensure design quality in the build.

• 6-10 years designing consumer mobile apps for fintech, payments, challenger banks, or the Big 5: Google, Apple, Facebook, Amazon, and Microsoft.
• You think differently, never settling for category norms.
• Strong systems thinking: component libraries, tokens, motion, and responsive rules.
• Fluency in Figma (auto-layout, variants), prototyping, and developer-ready specs.
• Data-driven mindset: comfortable with funnels, A/B testing, and iteration loops.
• Curiosity (or experience) in Web3/crypto, with a knack for simplifying complexity.
• Founder mindset: you own outcomes, communicate clearly, and ship relentlessly.

• Shape the user journeys at one of the fastest-scaling Web3 challenger banks.
• High ownership, zero bureaucracy, and direct impact on millions of users.
• Competitive comp + meaningful equity.
• Join a high-energy, no-BS team on track to be the next unicorn.
