We are seeking a QA Engineer with strong expertise in Blockchain technologies to ensure the quality, security, and reliability of blockchain-based applications.

Validate smart contracts for correctness, security vulnerabilities, gas optimization, and compliance with business logic.
Test blockchain operations including node setup, network configurations, consensus mechanisms, and transaction lifecycle.
Conduct API testing for blockchain services and integrations with off-chain systems.
Identify, log, track, and verify defects using defect management tools.
Collaborate closely with blockchain developers, architects, and DevOps teams throughout the SDLC.
Participate in security testing, including vulnerability assessment and basic penetration testing for smart contracts.
Support UAT, production validation, and post-deployment monitoring.
Ensure adherence to quality standards, best practices, and regulatory requirements (where applicable).

Essential skills/knowledge/experience:

- Ethereum / Polygon / BSC / Hyperledger Fabric / Corda (any one or more)
Experience with blockchain testing tools such as:
- Truffle, Hardhat, Ganache, Remix, Foundry (or similar)
Experience with API testing tools (Postman, REST clients).
Familiarity with CI/CD pipelines and DevOps practices.
Bachelor’s or Master’s degree in computer science, Engineering, or related field.

Desirable skills/expertise

Blockchain certifications or formal training will be an added advantage.
BFSI Industry experience a bonus.
Knowledge of test automation frameworks.
