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.
- Solid 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.
