  • Gas Optimization: Continuously optimize smart contract logic to minimize gas costs and improve transaction throughput.
  • Integration: Integrate Web3 libraries (Web3.js, Ethers.js) with our frontend applications to enable seamless wallet interactions.
  • Security Audits: Conduct rigorous code reviews and internal security audits to mitigate vulnerabilities before deployment.
  • Team Leadership: Mentor junior developers and establish best practices for smart contract development and deployment.

Qualifications

  • Education: Bachelor’s degree in Computer Science, Mathematics, or a related technical field.
  • Tools: Proficiency in development tools such as Hardhat, Truffle, Foundry, and Git.
  • Security: Deep understanding of blockchain security principles, smart contract vulnerabilities (Reentrancy, Overflow, etc.), and how to mitigate them.
  • Web3: Experience integrating with wallets (MetaMask, WalletConnect) and understanding of token standards (ERC-20, ERC-721, ERC-1155).
  • Communication: Excellent verbal and written communication skills with the ability to explain complex technical concepts to non-technical stakeholders.
