Senior Performance Test Engineer

Duties:

• Design and develop detailed performance test strategies plans scenarios and scripts to evaluate system behavior under various load conditions ensuring applications meet defined performance scalability and reliability benchmarks.
• Develop comprehensive performance testing protocols including load stress spike endurance and scalability testing. Assess system behavior across all layersapplication API database network and infrastructureto ensure optimal performance and resource utilization.
• Identify analyze and diagnose performance bottlenecks such as slow response times memory leaks CPU spikes thread contention and database query inefficiencies. Collaborate with development and DevOps teams to recommend and validate performance improvements.
• Monitor and analyze performance metrics logs and system behavior using appropriate monitoring and profiling tools. Maintain detailed reports of findings tuning efforts and performance benchmarks to ensure traceability and continuous improvement.
• Create and maintain comprehensive documentation of performance test scenarios workload models test results tuning recommendations and baseline metrics to support knowledge sharing and compliance standards.
• Work closely with cross-functional teamsincluding architects developers DevOps and product ownersto ensure performance requirements are defined early and validated throughout the development lifecycle.
• Provide actionable feedback and optimization recommendations evaluating system architecture database interactions caching mechanisms and infrastructure configurations to improve overall system efficiency.
• Implement enhance and maintain performance automation frameworks and CI/CD integrations to enable continuous performance testing and early detection of performance regressions.
