OSI Digital looking for a skilled Automation Test Engineer with strong programming expertise in Java and hands-on experience in developing and maintaining automated test solutions for web applications and REST APIs. The ideal candidate should have practical experience with Selenium, Rest Assured, automation framework development, SQL Server, and CI/CD integration using Jenkins and/or Azure DevOps.

The candidate will contribute to building scalable, reusable, and maintainable automation frameworks, integrating automated tests into continuous integration and delivery pipelines, and improving testing efficiency through AI-assisted automation tools.

Key Responsibilities

• Design, develop, execute, and maintain automated test scripts for web applications and REST APIs.
• Develop and enhance reusable automation frameworks using Java, Selenium, and Rest Assured.
• Implement UI automation covering functional workflows, regression scenarios, validations, and end-to-end business processes.
• Develop API automation scripts to validate REST endpoints, request and response payloads, status codes, headers, authentication, and error handling.
• Design positive, negative, boundary, and exception-handling test scenarios for APIs and web applications.
• Apply Java programming best practices, including object-oriented programming, collections, exception handling, and reusable component design.
• Integrate automated test suites into Jenkins and/or Azure DevOps pipelines and support scheduled and release-based executions.
• Analyze automation execution reports, troubleshoot failures, distinguish application defects from script or environment issues, and improve test stability.
• Use SQL queries and joins to validate application data, prepare test data, and verify database-level results using Microsoft SQL Server.
• Use Git for source control, branching, pull requests, code reviews, and collaborative automation development.
• Leverage AI tools to accelerate test case generation, automation script development, debugging, code refactoring, and framework improvements, while validating generated outputs before integration.
• Explore and contribute to modern automation solutions using Playwright with TypeScript and Python where appropriate.
• Collaborate with developers, manual QA engineers, business analysts, and DevOps teams to improve automation coverage and release quality.
• Maintain automation documentation, execution reports, reusable utilities, test data, and framework standards.
