Performance Test Engineer

Responsibilities

• Understand and review application requirements to identify performance testing needs and formulate detailed performance test plans and strategies.
• Design, develop, and execute performance, load, stress, endurance, and scalability test scenarios.
• Develop and maintain performance test scripts using Apache JMeter or similar performance testing tools.
• Identify appropriate workload models, user journeys, test data, concurrency levels, and performance benchmarks based on business requirements.
• Execute performance tests across different test environments and monitor application behavior under varying workloads.
• Analyze performance test results and identify bottlenecks related to application, database, API, network, CPU, memory, and other system components.
• Prepare detailed performance test reports, including test scenarios, workload configuration, response times, throughput, error rates, resource utilization, and identified bottlenecks.
• Conduct baseline, benchmark, load, stress, spike, and endurance testing as required.
• Collaborate with Developers, QA, DevOps, Database, and Infrastructure teams to investigate and resolve performance-related issues.
• Raise performance defects with appropriate evidence and work closely with development teams for root-cause analysis and resolution.
• Validate application performance after fixes and conduct regression/performance testing to ensure that issues have been resolved.
• Integrate performance testing into CI/CD pipelines and support continuous performance testing where applicable.
• Develop reusable performance test scripts and frameworks to reduce manual effort and improve testing efficiency.
• Monitor application and server performance during test execution using relevant monitoring and profiling tools.
• Coordinate with the client QA/Performance Testing team and other technology stakeholders for test planning, execution, and reporting.
• Generate performance test reports for every Sprint/initiative and provide walkthroughs of findings and recommendations to stakeholders.
• Proactively identify opportunities to improve application performance, test coverage, automation, and overall testing processes.
• Support pre-release and post-deployment performance validation where required.
• Investigate production performance issues, customer complaints, and application-related performance incidents.
• Identify potential performance risks and communicate them to relevant stakeholders with appropriate recommendations.
• Follow organizational policies, information security requirements, and applicable compliance standards.
• Maintain proper test documentation, evidence, scripts, results, and performance metrics.
• Work closely with business and technology stakeholders to understand performance expectations and ensure successful delivery of technology changes.
