Smart Contract QA Engineer, Atlas Oracle

BNB Chain; Kuala Lumpur; On-site; MYR 120,000 - 180,000; Full time

Job summary

BNB Chain is seeking an experienced Smart Contract QA Engineer to design and implement automated testing frameworks for oracle contracts, covering unit, integration, and end-to-end tests.

You will create security test cases, simulate on-chain conditions, assist in audits, and document results. Proficiency in Solidity and testing tools such as Hardhat, Truffle, or Foundry is required. This role emphasizes agile collaboration and ongoing benchmarking.

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or related field.
• 3+ years of experience in smart contract testing or development with Solidity and testing frameworks (Hardhat, Truffle, Foundry).
• Solid understanding of oracle mechanisms (Chainlink, Band Protocol) and attack vectors (flash loan, data tampering).
• Knowledge of blockchain concepts (consensus, gas optimization, event logs) and tools (Web3.js, Ethers.js).
• Ability to develop automated testing scripts using JavaScript/TypeScript, Python, or similar languages.
• Experience in security testing or code auditing is preferred, with knowledge of vulnerabilities (reentrancy, overflow).
• Strong communication and collaboration skills in an agile environment.

Responsibilities

• Design and implement automated testing frameworks for oracle smart contracts, covering unit tests, integration tests, and end-to-end tests.
• Develop and execute security test cases focusing on price data feeds, off-chain data retrieval, and multi-party consensus mechanisms.
• Simulate on-chain and network abnormal conditions to conduct stress and fault-tolerance testing.
• Collaborate with developers to perform vulnerability scans and assist in code audits before deployment.
• Create and maintain test documentation, defect reports, and quality assessment reports.
• Verify the accuracy of oracle node data and conduct performance benchmarking.
• Continue following blockchain testing tools and best practices and introduce new methodologies to improve efficiency.

Job description

Core Responsibilities:

• Design and implement automated testing frameworks for oracle smart contracts, covering unit tests, integration tests, and end-to-end tests.
• Develop and execute security test cases, focusing on core scenarios such as price data feeds, off-chain data retrieval, multi-party consensus mechanisms, and resistance to Sybil attacks.
• Simulate various on-chain and network abnormal conditions (e.g., high Gas fees, network latency, node failures) to conduct stress testing and fault tolerance testing.
• Work closely with the development team to perform vulnerability scanning and assist in code audits before contract deployment, ensuring no critical security risks.
• Create and maintain clear test documentation, defect reports, and quality assessment reports.
• Participate in verifying the accuracy of oracle node data and conducting performance benchmarking.
• Continuously follow blockchain testing tools and best practices, and introduce new testing methodologies to enhance efficiency.

Requirements:

• Bachelor’s degree or higher in Computer Science, Software Engineering, or a related field.
• 3+ years of experience in smart contract testing or development, with proficiency in Solidity and mainstream testing frameworks (e.g., Hardhat, Truffle, Foundry).
• Deep understanding of oracle mechanisms (e.g., Chainlink, Band Protocol) and awareness of common attack vectors (e.g., flash loan attacks, data tampering).
• Familiar with fundamental blockchain concepts (consensus mechanisms, Gas optimization, event logs, etc.) and tools (e.g., Web3.js, Ethers.js).
• Capable of developing automated testing scripts using JavaScript/TypeScript, Python, or similar languages.
• Experience in security testing or code auditing is preferred, with knowledge of common vulnerabilities (e.g., reentrancy, integer overflow) and mitigation methods.
• Strong communication skills and a collaborative mindset, adaptable to agile development environments.

Preferred Qualifications:

• Hands‑on experience in testing or developing oracle projects, with familiarity in decentralized data sources and node networks.
• Knowledge of zero‑knowledge proofs, TEE (Trusted Execution Environment), and other privacy‑related oracle technologies.
• Experience with performance testing tools (e.g., K6, Gatling) or on-chain monitoring tool development.
• Open‑source contributions to blockchain projects on GitHub or demonstrable testing case portfolios.
