Role Overview

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. The role involves writing secure and gas-efficient contracts and integrating them into real, production front-ends. This position 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.
