Key Responsibilities:

📍Design, develop, and deploy smart contracts (primarily Solidity or Vyper) for features such as staking, token issuance, multi-sig, governance, and trading. 📍Integrate on-chain contracts with backend systems and off-chain data using oracles and event listeners (e.g., The Graph, Chainlink). 📍Optimize gas usage, ensure contract upgradeability, and maintain test coverage with unit/integration tests using frameworks like Hardhat or Foundry. 📍Contribute to wallet integrations, token standards (ERC-20, ERC-721, ERC-1155), and bridging mechanisms across chains. 📍Review and audit smart contracts internally and externally, identifying security vulnerabilities and business logic issues. 📍Collaborate with product, backend, and frontend teams to deliver blockchain features end-to-end. 📍Stay up to date with latest L1/L2 developments, EIPs, and tooling to propose and implement improvements.

Required Qualifications:

📍4+ years of software engineering experience, with 2+ years specifically in blockchain development. 📍Strong experience with Solidity, and knowledge of EVM internals, gas optimization, and contract design patterns. 📍Familiarity with Ethereum and L2 ecosystems (Polygon, Arbitrum, Optimism, zkSync). 📍Proficient with blockchain development tools: Hardhat, Foundry, Truffle, Web3.js, Ethers.js. 📍Deep understanding of token standards, DeFi protocols, and on-chain governance. 📍Experience with multisig wallets, time locks, oracles, and decentralized identity (DID) frameworks. 📍Comfortable working with Git, CI/CD, Docker, and collaborative environments.
