## About the role

We're looking for a mid-level to senior Flutter engineer who understands DeFi — not just how to build a beautiful mobile app, but how DeFi products (lending, staking, swaps, savings, and self-custody wallets) actually work on-chain. You'll build consumer-facing DeFi products end to end, translating complex on-chain flows into interfaces that are clear, trustworthy, and delightful. You'll collaborate closely with backend, product, and design to ship money-movement features that are secure and reliable.
