What You Will Be Doing

• Design, develop, and maintain enterprise-grade automation frameworks using Python and PyTest
• Build automated testing solutions for APIs, backend services, web applications, and cloud platforms
• Partner closely with Software Engineers throughout the development lifecycle to improve software quality
• Create reusable automation libraries and testing utilities that scale across multiple engineering teams
• Develop automated regression, smoke, functional, integration, and end-to-end test suites
• Integrate automated testing into CI/CD pipelines to support continuous delivery
• Identify quality gaps early through automation and proactive testing strategies
• Debug complex software issues and work alongside developers to resolve production defects
• Contribute to automation standards, coding best practices, and quality engineering initiatives
