We are Fam, a Shanghai-based company building a one-stop community engagement hub for the web3 era. Founded by ex-Googlers and backed by leading international VCs along with dozens of top angel investors and creators from both web2 and web3, we stay small, focused, and driven by product excellence and the people behind it.
What is this role?
This is a full-time senior Blockchain Developer / Web3 Backend Engineer position. The role centers on smart-contract and backend engineering for our NFT and community platform, and it is open to candidates working remotely from anywhere.
What will you do?
- Design, develop, and deploy NFT-related smart contracts-primarily in Solidity on EVM-compatible chains-while handling testing, security audits, and gas optimization.
- Build and maintain the backend services and off-chain databases that interact with the blockchain, including on-chain and off-chain data analysis and processing pipelines.
- Ensure system security, scalability, and stability by participating in capacity planning, performance tuning, and troubleshooting.
What makes you a great fit?
You bring a solid computer-science foundation with strong data-structure and algorithm skills, plus proven programming and problem-solving abilities. You have hands-on experience developing and optimizing smart contracts in Solidity, using tools such as Truffle and Hardhat, and working with libraries like OpenZeppelin. You are comfortable with the ERC-721, ERC-721A, and ERC-1155 standards, and you have production experience with Golang or another backend stack. You also know your way around MySQL, MongoDB, Redis, and data-processing tools such as Kafka. Prior work launching large-scale or complex smart contracts on Ethereum, contributing to DeFi projects, or working in security-focused environments is highly valued. All communication happens in English.
What's in it for you?
We offer a competitive salary plus equity, and the position supports fully remote work so you can collaborate from anywhere.
