• Collaborate with cross-functional teams, including developers, product managers, and designers, to ensure software meets business and technical requirements.
• Analyze test results and performance metrics, providing recommendations for improving system performance and reliability.
• Develop and execute performance test scripts and scenarios using tools like JMeter, Gatling, or LoadRunner.
• Simulate high-volume load conditions and analyze system behavior under stress.
• Monitor application performance in different environments, identifying bottlenecks in application servers, databases, APIs, and network layers.
• Work closely with DevOps/infra teams to optimize system performance and scalability.
• Participate in code reviews, emphasizing testability and performance concerns.
• Maintain automated test scripts and testing frameworks for both functional and performance testing.
• Continuously improve software testing and development practices.
• Review requirements and technical design documents to provide early, constructive feedback.
• Investigate and resolve product complaints or reported performance issues under company guidelines.
• Participate in Agile ceremonies such as sprint planning and backlog grooming.
