We leverage the power of digital assets and blockchain to build an inclusive financial ecosystem to advance the freedom of money and improve financial access for people around the world.

We are looking for a Java Backend Engineer with on-chain development experience to join our On-Chain Payments team. You will build the backend infrastructure that bridges traditional banking rails and blockchain networks, enabling seamless fiat-to-crypto conversion and on-chain transaction processing.

  • Integrate with blockchain networks (EVM-compatible chains and others) for on-chain fund settlement
  • Build APIs and services that connect banking channels with on-chain liquidity
  • Collaborate with the P2P and Fiat teams on cross-system integrations
  • Ensure transaction reliability, idempotency, and fault tolerance across on-chain and off-chain systems
  • Monitor chain status and handle edge cases such as reorgs, gas spikes, and failed transactions

    • Requirements

  • 3–5 years of Java backend development experience
  • Experience with Web3/blockchain development: on-chain interactions, wallet integrations, smart contract calls
  • Familiarity with EVM chains (Ethereum, BSC, etc.) or other L1/L2 ecosystems
  • Proficiency in Spring Boot and common distributed system components
  • Fluency in English is required to be able to coordinate with overseas partners and stakeholders. Additional languages would be an advantage.
  • Experience in fintech or crypto payment systems is a strong plus
