We re looking for a skilled Blockchain Developer to design, build, and maintain smart contracts and decentralized applications across EVM-compatible chains. You ll work with product, design, and engineering teams on Web3 projects including DeFi platforms, NFT marketplaces, and decentralized exchanges, writing secure and gas-efficient contracts and integrating them into real, production front ends. This role suits someone who thinks in adversarial terms about contract security and enjoys owning a feature from architecture through mainnet deployment.

Key Responsibilities

• Design, develop, test, and deploy smart contracts using Solidity on Ethereum and EVM-compatible chains such as Polygon, Arbitrum, Optimism, or Base.

• Build and maintain decentralized applications (dApps) for DeFi, NFT, and exchange platforms.

• Integrate smart contracts with front-end applications using Web3.js, Ethers.js, or wagmi.

• Write comprehensive tests, including unit and invariant tests, using Foundry or Hardhat.

• Optimise smart contracts for gas efficiency and transaction performance.

• Identify and mitigate common security vulnerabilities such as reentrancy, access control failures, and oracle manipulation.

• Collaborate with cross-functional teams including product, design, and backend engineering.

• Monitor and upgrade deployed contracts in response to security issues or network upgrades.

• Document contract functionality, architecture, and deployment procedures.

• Stay current with blockchain trends, Layer-2 developments, and evolving security best practices.

Required Skills & Qualifications

• Strong proficiency in Solidity and solid understanding of the Ethereum Virtual Machine (EVM).

• Hands-on experience with Foundry or Hardhat for testing and deployment.

• Experience with Web3.js, Ethers.js, or wagmi for front-end integration.

• Understanding of common smart contract standards (ERC-20, ERC-721, ERC-1155).

• Working knowledge of Git and version control systems.

• Strong problem-solving and analytical skills, with an eye for security-critical code.

Good to Have

• Experience deploying to Layer-2 networks such as Arbitrum, Optimism, Base, or zkSync.

• Experience integrating with established DeFi protocols such as Uniswap, Aave, or Chainlink.

• Exposure to non-EVM ecosystems such as Solana (Rust) or other chains.

• Experience with static analysis tools such as Slither, and prior participation in a smart contract audit.

• Familiarity with node and RPC providers such as Alchemy, Infura, or QuickNode.

• Understanding of account abstraction and modern wallet integration (RainbowKit, WalletConnect).

Eligibility

• 2+ years of hands-on blockchain development experience.

• Bachelor s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

• Available to work on-site in Gurugram, 5 days a week.

What You ll Get

• Opportunity to work on cutting-edge Web3 and blockchain projects across DeFi, NFT, and exchange platforms.

• A collaborative, high-performance engineering culture.

• Competitive compensation based on experience.

• Exposure to global clients across DeFi, NFT, and enterprise blockchain.
