Remitee, a fast-growing fintech specialized in international payments, is looking for a Senior Blockchain Engineer to join our Technology team.

Our Blockchain team is building the on-chain infrastructure behind Remitee's treasury and cross-border settlement: stablecoin liquidity flows, tokenized balances and on-chain accounting that reconciles with our core ledger. In this role you will design, write, test and ship smart contracts and the backend services that interact with them, running in production and moving real value for our Treasury team and our banking and payment partners. You will own technical decisions end-to-end, from contract architecture and security to custody integration, gas management and monitoring.

We are looking for a developer who has already taken blockchain products to mainnet, not just tutorials or hackathon projects, and who understands what it takes to operate them safely in a regulated financial environment.

Key Responsibilities
- Design, develop, test and deploy Solidity smart contracts on EVM networks,



including token contracts (ERC-20 and custom token logic), access control and upgradeable patterns.
- Build and maintain the backend services that interact with the chain: transaction submission, nonce and gas management, event indexing and reconciliation against our internal ledger.
- Integrate with digital asset custody and wallet infrastructure (MPC wallets, policy engines, transaction signing workflows).
- Implement stablecoin flows (e.g. USDC) for funding, settlement and liquidity across corridors, including on/off-ramp and cross-chain integrations (e.g. Circle CCTP or bridge protocols).
- Own smart contract security: threat modeling, comprehensive test suites, fuzzing and static analysis, and coordination with external auditors.
- Evaluate and benchmark EVM networks (L1s and L2s) considering finality, cost, tooling, custody support and liquidity.
- Set up observability for on-chain components: monitoring and alerting on failed o
