- Problem-Solving & Autonomy: Ability to independently troubleshoot complex on-chain issues, debug smart contracts, and drive technical tasks to completion with minimal supervision.
- Smart Contract Security Best Practices: Strong understanding of common smart contract vulnerabilities and how to mitigate them.
- Smart Contract Development Tools & Testing Frameworks: Experience with tools like Hardhat, Foundry, Truffle or Anchor for development, testing, and deployment.
- Smart Contract Upgrade Patterns: Familiarity with various smart contract upgradeability patterns
- Off-Chain Scripting/Interaction: Experience writing scripts (e.g., using Typescript/Javascript with Ethers.js/Web3.js, or GoLang) to interact with and manage smart contracts.
- CI/CD for Smart Contracts: Experience with continuous integration and continuous deployment pipelines for smart contracts.
- Understanding of Distributed Systems Principles: A good grasp of concepts relevant to building and interacting with distributed systems.
