Senior Frontend Engineer (Fintech / Web3)

About the Project

We’re building a borderless, self-custodial remittance app that lets users send, receive, and hold stablecoins (USDC / EURC) across countries, with on/off-ramp integration, account-abstraction wallets, and virtual bank accounts.

Our goal is to make stablecoin payments as easy as Revolut or Wise.

You’ll be joining a small, product-driven team building the first version of the app from the ground up.

• Implement user onboarding, KYC, and account-abstraction wallet flows.

• Set up reusable UI components, design systems, and frontend documentation.
