Blockchain Specialist for NFT & DeFi Platform
Budget: £36 – £0 GBP
About CAW
CAW is a Social-Fi platform merging the familiarity of social networking with blockchain-native ownership. Users mint and manage NFTs, participate in DeFi protocols, and build tokenized communities — all within an interface designed to feel natural to people who have never touched Web3 before. The stack covers ERC-721 and ERC-1155 NFTs, social token issuance, staking, token swaps, liquidity pools, and secure wallet integration, built on Solidity, Node.js, React/TypeScript, and Web3.js.
The Role
You will own the smart contract layer — from architecture through audit — and work directly with product, backend, and frontend teams to ship DeFi and NFT features that are secure, efficient, and ready for production. This is a technical leadership position: your design decisions will define how the protocol evolves, and your judgment will set the bar for quality across the engineering team.
What You Will Do
– Design and develop Solidity smart contracts — covering NFT minting and management (ERC-721/1155), social token issuance, staking, swaps, and liquidity pool mechanics.
– Own protocol architecture — making pragmatic decisions on contract upgradeability, gas efficiency, and cross-contract composability.
– Lead security reviews and audits — identifying reentrancy, oracle manipulation, and access control risks before code reaches production.
– Drive backend and frontend integration — collaborating with Node.js and React/TypeScript engineers to ensure contract interfaces are clean and well-documented.
– Set engineering standards — through code reviews, testing strategy (Hardhat/Foundry), and documentation that the rest of the team can build on.
