Blockchain & Crypto Integration Engineer

About the role

USDT TRC-20 and TRX payments are already a meaningful share of customer top-ups. As we add USDC, BTC Lightning, and SOL settlement, plus on-chain treasury operations for cross-border partner payouts, we expect to bring on a dedicated integration engineer who owns the blockchain interface end-to-end — wallet derivation, address pool rotation, transaction polling, on-chain confirmation policy.

What you'll do

  • Extend the payment-processor plugin architecture to support additional chains (Ethereum L2s, Solana, Bitcoin Lightning) under a unified interface.
  • Own the HD wallet derivation, address pool management, and on-chain polling workers for each chain.
  • Implement on-chain settlement for partner payouts in stablecoin, including FX hedging coordination with the treasury team.

What we expect

  • 3+ years building production crypto payment systems — not DeFi protocols, but boring custody-aware integration work.
  • Direct experience with at least two of: Tron, Ethereum, Solana, or Bitcoin chain APIs (explorer endpoints + RPC nodes), plus on-chain confirmation strategies for at-least-once delivery.
  • Working knowledge of HD wallet (BIP32/BIP44) derivation, key custody best practices, and the practical security tradeoffs between hot/warm/cold wallet architectures.

Stack we use

Go for the on-chain polling workers, PostgreSQL for transaction state, chain RPC + explorer endpoints across Tron / Ethereum / Solana / Bitcoin networks, HSM or KMS-backed key management for production custody.

Compensation

On the radar. Compensation is calibrated to local cost of living when we open this role — we publish bands when we begin interviewing, not before. USD-denominated regardless of jurisdiction, contractor or employment depending on your legal situation.
