  • Solid understanding of smart contract security and vulnerabilities
  • Experience with Hardhat, Foundry, or similar frameworks
  • Strong software engineering fundamentals (testing, Git, CI/CD)
  • Ability to work across multiple projects and adapt quickly
  • Experience with DeFi protocols, staking, or token economies
  • Experience working with auditors or security reviews
  • Familiarity with upgradeable contracts (proxy patterns)
  • Backend experience (Node.js / TypeScript)
  • Experience in client-facing or consulting environments
