ZL Tech

• Gather non-functional requirements and translate them into performance test strategies, workload models, and SLAs (response time, throughput, concurrency, error rate).
• Design, script, and execute load, stress, endurance, spike, and scalability tests using tools such as JMeter, LoadRunner.
• Perform API/web services performance testing (REST/SOAP) and database-level performance validation.
• Analyse test results to identify bottlenecks (application, database, network, or infrastructure) and work with engineering teams to resolve them.
• Prepare detailed performance test reports, dashboards, and executive summaries with clear recommendations.
• Contribute to capacity planning and pre-production performance sign-off for major releases.

• 7 years of overall QA/testing experience, with 3+ years focused specifically on performance testing.
• Strong hands-on experience with JMeter and/or LoadRunner working on Enterprise Applications.
• Solid understanding of performance testing concepts: load, stress, soak/endurance, spike, and scalability testing.
• Experience with performance scripting for HTTP/HTML, REST/SOAP web services, and correlation/parameterization techniques.
• Working knowledge of SQL for backend validation and query performance analysis.
• Basic scripting ability (Java, Python, or Shell) for test data setup and automation of test workflows.
• Good understanding of the full performance test lifecycle — requirement gathering, planning, scripting, execution, analysis, and reporting.
• Strong at Debugging/Troubleshooting/Log Analysis.

• Exposure to cloud environments (AWS/Azure) and containerized applications (Docker/Kubernetes).
• Experience integrating performance tests into CI/CD pipelines
• Knowledge of microservices architecture and distributed system performance considerations.
• Performance testing certifications (e.g., LoadRunner/JMeter certification, Certified Performance Tester).

• Bachelor’s degree in Computer Science, Information Technology, or a related field.
• Strong analytical and problem-solving skills with the ability to work independently under release timelines.
• Excellent written and verbal communication skills to present findings to technical and business stakeholders.
