About the Role

We are looking for a Senior Performance Tester who can independently design, execute, and analyze performance test strategies using JMeter and BlazeMeter, while working closely with application development, DevOps, and infrastructure teams to identify and resolve performance bottlenecks across the application stack.

Key Responsibilities

• Design and implement performance, load, stress, soak, and scalability test plans using Apache JMeter and BlazeMeter for web, API, and microservices-based applications.
• Collaborate with application development teams to understand system architecture, transaction flows, and critical business scenarios to be tested.
• Translate non-functional requirements (NFRs) into measurable performance test scenarios and SLAs (response time, throughput, error rate, concurrency).
• Build and maintain reusable JMeter test scripts (HTTP, REST/SOAP APIs, JDBC, WebSocket) including correlation, parameterization, and assertions.
• Configure and manage test execution on BlazeMeter, including distributed load generation, cloud-based test scheduling, and CI/CD integration.
• Monitor system resources (CPU, memory, thread pools, DB connections, GC behavior) during test execution in coordination with infra/dev teams.
• Analyze test results, identify bottlenecks (application code, database queries, network, infrastructure), and work with developers/architects to drive root-cause resolution.
• Prepare and present performance test reports, trend analysis, and executive summaries to technical and leadership stakeholders.
• Integrate performance testing into CI/CD pipelines (Jenkins/Azure DevOps/GitHub Actions) for shift-left performance validation.
• Define and maintain performance testing standards, best practices, and reusable frameworks/templates across projects.
• Participate in capacity planning and production readiness reviews for new releases or infrastructure changes.
• Mentor junior performance testers and review their scripts/test plans.

Required Skills & Experience

• 6+ years of hands-on experience in performance testing using Apache JMeter.
• Strong working experience with BlazeMeter (test scheduling, cloud load generation, reporting, CI/CD integration).
• Solid understanding of performance testing concepts: load, stress, spike, soak, endurance, and scalability testing.
• Experience testing REST APIs, microservices, and database-driven applications.
• Ability to read and interpret application logs, APM tools (AppDynamics, Dynatrace, New Relic, or Azure Application Insights) to correlate performance issues.
• Working knowledge of scripting (Groovy/BeanShell within JMeter, or Shell/Python) for custom test logic.
• Familiarity with CI/CD tools (Jenkins, Azure DevOps, GitHub Actions) and integrating performance tests into pipelines.
• Understanding of client-server architecture, HTTP protocols, caching, load balancing, and database performance tuning basics.
• Strong communication skills — able to work directly with developers, architects, and business stakeholders to explain findings and negotiate fixes.
• Experience preparing detailed performance test reports and presenting results to both technical and non-technical audiences.
