QA Test Automation Engineer

Key Responsibilities: Design and automate robust API tests using Postman, scripting libraries, validating high-throughput transactional endpoints, ledger events, and external partner webhooks. Collaboration & Growth: Partner closely with backend developers, implementation teams, and release managers to integrate automated tests into CI/CD deployment pipelines and maintain continuous regression coverage. Technical Requirements : 4-6 years of automated QA experience with deep, hands-on expertise in Postman (collections, environment variables, pre-request scripts, JavaScript assertions), RESTful API protocols, and JSON/XML validation Bonus Skills: Familiarity with Newman CLI integration in Jenkins/GitHub Actions, basic Python or JavaScript automation frameworks, SQL verification, and exposure to fintech or blockchain ledger systems., Develop, structure, and maintain modular Postman test collections with advanced JavaScript assertions for response schema, status codes, latency, and business logic. Automate collection execution via Newman CLI inside CI/CD pipelines (e.g., Jenkins, GitHub Actions, GitLab CI) for seamless regression testing. Validate API endpoints, payload variations, edge cases, authentication workflows (OAuth2, bearer tokens, API keys, mTLS), and asynchronous webhook events. Perform backend data reconciliation by executing SQL queries to verify database state transitions following API transaction execution. Log, prioritize, and track defects in Jira, providing clear reproduction steps, network request/response logs, and environment configurations. Collaborate with development and implementation teams to review API specifications (Swagger/OpenAPI) and define acceptance criteria before feature development begins.
