Role in brief
Golfiuns is hiring a Smart Contract Developer to build and deploy smart contracts for DeFi, NFTs, and DAOs. This role involves designing on-chain solutions, optimizing performance, and ensuring contract security. It suits a developer with 1-3 years of experience in Solidity and EVM, looking to contribute to core protocol development.
About the role
This role focuses on the complete lifecycle of smart contract development, from initial design to deployment and maintenance. You will be responsible for creating contracts for various Web3 applications, including decentralized finance, non-fungible tokens, and decentralized autonomous organizations. A key part of the work involves architecting the underlying logic for these on-chain solutions.
A significant aspect of this position is ensuring the efficiency and security of the smart contracts you develop. This includes optimizing code for gas usage and conducting internal security reviews to identify and mitigate vulnerabilities. You will also integrate these contracts with other system components, such as backend and frontend interfaces.
Collaboration is central to this role, as you will work closely with product, backend, and security teams throughout the development process. Your input will be valued in protocol design and technical decision-making, contributing to the overall direction of the projects. Success in this position means delivering secure, efficient, and well-integrated smart contract solutions.
The salary for this full-time remote position ranges from $90,000 to $100,000 annually.
