Description

  • Design and implement automated unit, integration, and end-to-end testing frameworks for oracle smart contracts.
  • Develop and execute security test cases for price feeds, off-chain data retrieval, multi-party consensus, and Sybil-attack resistance.
  • Simulate high gas fees, network latency, node failures, and other abnormal conditions for stress and fault-tolerance testing.
  • Partner with developers on vulnerability scanning and pre-deployment code audits to identify critical security risks.
  • Create and maintain test documentation, defect reports, and quality assessment reports.
  • Verify oracle node-data accuracy and conduct performance benchmarks.
  • Research blockchain testing tools and best practices, introducing improved testing methodologies.

Requirements

  • Bachelor’s degree or higher in Computer Science, Software Engineering, or a related field.
  • 3+ years of smart contract testing or development experience.
  • Proficiency in Solidity and testing frameworks such as Hardhat, Truffle, or Foundry.
  • Understanding of oracle mechanisms such as Chainlink and Band Protocol, including attack vectors such as flash loans and data tampering.
  • Knowledge of blockchain concepts including consensus mechanisms, gas optimization, and event logs.
  • Experience with Web3.js, Ethers.js, and automated test scripting in JavaScript/TypeScript, Python, or similar languages.
  • Security testing or code-auditing experience, including vulnerabilities such as reentrancy and integer overflow, is preferred.
  • Strong communication and collaboration skills in agile development environments.
  • Hands-on oracle project experience, including decentralized data sources and node networks, is preferred.
  • Knowledge of zero-knowledge proofs, TEE, privacy-focused oracle technologies, performance testing tools such as K6 or Gatling, on-chain monitoring, or relevant open-source contributions is preferred.
