Responsibilities

📍Design, develop, test, and deploy secure and efficient smart contracts on EVM-based blockchains (Ethereum, Polygon, BNB Chain, etc.). 📍Write clean, well-structured, and optimized Solidity code with consideration for gas efficiency and security. 📍Implement smart contract standards (ERC-20, ERC-721, ERC-1155, etc.) and custom token logic where required. 📍Collaborate with frontend and backend developers to integrate smart contracts with Web3 libraries (ethers.js, web3.js). 📍Conduct smart contract audits (internal and via external tools like Slither, MythX, Hardhat security plugins). 📍Develop and maintain test suites for contracts using Hardhat/Truffle/Foundry with Mocha/Chai/Jest. 📍Configure deployment pipelines, upgradeable contracts (using OpenZeppelin libraries), and manage migrations. 📍Implement event logging for dApp interaction and efficient indexing (The Graph or similar). 📍Provide technical insight into blockchain architecture and contribute to dApp design and scalability. 📍Stay updated with the latest Ethereum ecosystem developments, Layer-2 scaling, and gas optimization techniques.

Required Skills

📍Primary (Smart Contracts – Expert) 📍3+ years of professional experience with Solidity and EVM-based contract development. 📍Strong knowledge of smart contract standards (ERC-20, ERC-721, ERC-1155, ERC-4626, ERC-3643 etc.). 📍Experience deploying contracts on Ethereum, Polygon, Arbitrum, Optimism, or other EVM-compatible chains. 📍Familiarity with development frameworks: Hardhat, Truffle, Foundry, Brownie. 📍Strong grasp of smart contract security (reentrancy, overflows, access control, frontrunning, etc.). 📍Hands-on experience with gas optimization techniques.

The crypto industry is evolving rapidly, offering new opportunities in blockchain, web3, and remote crypto roles — don’t miss your chance to be part of it.
