We are seeking a Blockchain Web3 Engineer with hands-on experience in smart contracts and blockchain infrastructure. The role involves developing, deploying, and maintaining smart contracts and Web3 components, as well as managing blockchain nodes and related infrastructure.

Required Skills
  • Strong understanding of blockchain fundamentals: transactions, blocks, gas/fees, wallets/keys, RPC, finality, and consensus basics.
  • Hands-on experience with smart contracts (Solidity preferred) and development tools (Hardhat, Foundry, Truffle, Remix).
  • Experience with EVM-based chains (Ethereum, Polygon, Arbitrum, Optimism, BSC) or enterprise chains (Hyperledger Fabric, Corda, Quorum).
Roles & Responsibilities
  • Design, develop, and maintain smart contracts and Web3 backend components.
  • Manage contract deployment pipelines (ABI/versioning, migrations, upgrades) and implement secure patterns.
  • Deploy, configure, and operate blockchain nodes (full, archival, validator) and supporting infrastructure.
  • Implement tooling for node monitoring, RPC performance, logging, and alerting.
  • Handle blockchain reliability concerns: re-orgs, finality, peer connectivity, RPC failover, and rate limiting.
