Blockchain / Web3 Developer

WazirX is India's most widely used cryptocurrency exchange platform, handling billions of dollars in monthly trading volume. As a Blockchain/Web3 Developer, you will build the smart contract infrastructure, DeFi protocol integrations, and blockchain data indexing systems that power WazirX's trading, staking, and NFT platforms. Your responsibilities include writing and auditing Solidity smart contracts on Ethereum and Polygon networks, building ERC-20 and ERC-721 token contracts with OpenZeppelin security standards, developing Graph Protocol subgraphs for on-chain event indexing, integrating wallet connections via WalletConnect and MetaMask, building cross-chain bridge interfaces, and contributing to WazirX's internal blockchain research blog. Security is paramount — you will participate in smart contract audits and work with external auditors like CertiK. This role offers exposure to the full Web3 stack in a regulated, well-funded Indian crypto environment.
