- Hands-on experience with smart contracts using Solidity (preferred) and development tooling (Hardhat/Foundry/Truffle/Remix).
- Experience working with EVM-based chains (Ethereum/Polygon/Arbitrum/Optimism/BSC) or enterprise chains (Hyperledger Fabric/Corda/Quorum).
Roles & Responsibilities
Smart Contract Engineering & Web3 Development
- Design, develop, and maintain smart contracts (Solidity/Vyper or relevant stack) aligned with product and security requirements.
- Build backend/Web3 components for contract interaction, including transaction orchestration, signature flows, nonce management, and gas strategies.
- Integrate and manage Web3 SDKs.
- Develop and manage contract deployment pipelines, covering ABI/versioning, migrations, upgrade strategies (proxy patterns), and release coordination.
- Implement secure patterns for smart contracts and support smart contract testing.
Node Operations & Infrastructure
- Deploy, configure, and operate blockchain nodes and supporting infrastructure, including full nodes/archival nodes, RPC endpoints, and validator nodes (as applicable).
- Manage node upgrades, chain configuration changes, and incident response for production networks.
- Implement operational tooling for node health checks, RPC performance monitoring, log aggregation, and alerting.
- Handle blockchain-specific reliability concerns such as re-org handling, finality considerations, peer connectivity, RPC failover, and rate limiting.
