Job Summary (List Format) Blockchain QA Engineer
- Ensure correctness, security, and reliability of a verifiable financial data platform anchored to blockchain.
- Validate data-heavy pipelines and ensure ISO 20022 semantic consistency.
- Test blockchain attestation logic, including cryptographic proofs and smart contracts.
- Validate end-to-end chain of custody for financial records: canonicalization, cryptographic integrity, blockchain attestations, selective disclosure, and reconciliation.
- Design, implement, and maintain automated test suites for backend APIs (Golang), smart contracts (Solidity/EVM), and data pipelines (ETL/normalization).
- Conduct rigorous manual testing for complex financial transaction edge cases.
- Perform functional and security testing of smart contracts; validate on-chain state transitions and event emissions.
- Test scenarios involving chain reorganizations, gas spikes, network latency, and failed attestations using tools like Hardhat, Foundry, or Truffle.
- Validate ISO 20022 semantic mapping and perform differential testing to ensure data fidelity.
- Test Merkle tree construction and proof inclusion logic.
- Conduct load and fuzz testing on data ingestion, proof-generation services, smart contracts, and API endpoints.
- Collaborate with Cybersecurity to validate identity and provenance layers.
- Integrate blockchain testing into CI/CD pipelines (ArgoCD/GitHub Actions).
- Develop custom scripts (Python, Go, JS) for test data and event stream simulation.
- Track and document bugs, providing clear reproduction steps.
- Requires 4+ years of QA/SDET experience, 2+ years in blockchain/Web3 QA, and proficiency in at least one programming language (Golang, Python, JS/TS).
- Experience with blockchain testing frameworks (Foundry, Hardhat), API testing tools, and cryptographic primitives.

What is a QA in a job?
QA stands for Quality Assurance, which is a process or department in a company responsible for ensuring that products or services meet a certain level of quality
In a job, QA may refer to the role of a Quality Assurance Engineer or a Software Testing Engineer, who is responsible for designing and implementing quality control procedures to ensure that products or services meet the company's quality standards
A QA Engineer may be involved in various stages of the product or service development cycle, from designing and planning quality control procedures to executing testing and analysis to identify and address issues or defects
They may also work closely with other departments, such as engineering, product management, and customer support, to ensure that customer needs are met and that products or services meet the desired level of quality
In the context of Web3, Quality Assurance (QA) refers to the process of testing decentralized applications (DApps), smart contracts, and other blockchain-based solutions to ensure their functionality, security, and performance
The role of a QA Engineer in Web3 may involve designing and implementing testing strategies to identify and fix bugs, vulnerabilities, and other issues that could affect the user experience, data integrity, or network security
Some of the specific responsibilities of a QA Engineer in Web3 may include:
- Developing test cases and scenarios for DApps, smart contracts, and other blockchain-based solutions
- Conducting automated and manual testing to identify and fix issues
- Collaborating with developers, product managers, and other stakeholders to ensure the quality of the product
- Ensuring that DApps and smart contracts are compatible with different blockchain networks and standards
- Contributing to the development of tools and frameworks for testing Web3 applications.
