01Job Description
We are looking for a versatile and meticulous QA / Applications Test Engineer with a strong background in testing .NET applications alongside web, API, and legacy enterprise software. In this role, you will design, implement, and execute comprehensive manual and automated testing strategies to ensure the highest quality, reliability, and security across our software ecosystem.
The ideal candidate will feel equally comfortable testing core C#/.NET desktop or web applications as they do validating third-party integrations, backend databases, and non-.NET auxiliary applications.
02Key Responsibilities
Test Strategy & Execution: Create, maintain, and execute comprehensive manual and automated test cases for .NET (C#, .NET, Oracle) applications as well as broader enterprise software.
Automation Engineering: Build and extend scalable automation frameworks using tools like Selenium, Playwright, or Cypress (with C# or JavaScript/TypeScript) to reduce manual regression overhead.
API & Integration Testing: Validate RESTful and SOAP web services using utilities like Postman or SoapUI, ensuring seamless end-to-end data flows between .NET systems and external applications.
Defect Management: Identify, isolate, record, and track software bugs using Jira or Azure DevOps (TFS). Work closely with cross-functional development teams to ensure quick resolution.
Database Verification: Write and run complex SQL queries to perform backend data validation, verify data integrity, and check migration workflows.
CI/CD Integration: Integrate automated test suites into DevOps build pipelines (Jenkins, GitHub Actions, or Azure Pipelines) to facilitate continuous testing.
