Key Responsibilities :

- Develop, maintain, and execute comprehensive test plans and test cases.

- Lead manual and automated testing efforts across various platforms (web, mobile, API, desktop).

- Identify, log, and track defects using defect management tools (e.g., JIRA, Azure DevOps).

- Participate in requirements reviews and provide feedback on testability and quality risks.

- Collaborate with cross-functional teams (Dev, BA, PM, DevOps) to ensure clarity on requirements and timelines.

- Perform regression, functional, integration, performance, and user acceptance testing.

- Support test automation efforts; write and maintain scripts in tools such as Selenium, Postman, or JMeter.

- Mentor junior testers and review their test cases and results.

- Ensure compliance with QA standards, processes, and best practices.

- Provide test estimates and contribute to test strategy and planning.

- Contribute to the testing of MES applications and validate shop floor workflows, data capture, and system integration with ERP platforms.

- Work closely with manufacturing and business teams to understand MES use cases, system behaviors, and ensure production-readiness of MES functionalities.
