Performance Tester Job Description: Must have: Design and develop load, stress, endurance, and scalability tests for web applications, APIs, and backend systems using Apache JMeter . Write test plans, scenarios, and scripts based on business requirements, technical specifications, and system performance objectives. Execute performance testing for both front-end and back-end systems, simulating real-world user loads. Monitor system performance during testing, including response times , transaction times , throughput , and resource utilization ( CPU, Memory, and Disk I/O ). Analyse performance test results to identify bottlenecks, performance degradation, and areas for optimization. Provide detailed performance reports, including recommendations for improving system performance. Present findings to stakeholders and collaborate with development teams to resolve performance issues. Collaborate with developers and system engineers to fine-tune applications and infrastructure based on test results. Develop scripts for automated regression and load testing to ensure system stability over time. Work closely with development teams to ensure performance considerations are integrated into the development lifecycle. Maintain proper documentation of test plans, test cases, results, and lessons learned from performance testing. Experience using Apache JMeter for performance testing (creating and executing test scripts, reporting, and analysis). Strong understanding of performance testing concepts (load testing, stress testing & scalability testing). Strong problem-solving skills, particularly in diagnosing performance issues and identifying root causes. Ability to analyse performance test results and generate actionable insights. Excellent verbal and written communication skills to present test results and collaborate with cross-functional teams. Ability to document test cases, issues, and recommendations clearly. Experience with cloud-based performance testing using platforms such as AWS , and Azure . Experience working in Agile or DevOps or DevSecOps environments. Good to have: Familiarity with CI/CD pipelines and tools like Azure DevOps , Jenkins and GitLab for integrating tests. Knowledge on other Performance Test Tools like Gatling , K6 and Locust. Certifications related to performance testing or JMeter, such as Certified JMeter Tester or ISTQB Performance Tester. Bachelors degree in computer science , Information Technology , or a related field. 3+ years of experience in performance testing, with direct expertise in Apache JMeter or similar tools. Experience in performance testing in a web or cloud-based application environment is highly desirable. Familiarity with load balancing, database performance tuning, or web server configurations. Automate performance tests and integrate them into CI/CD pipelines for continuous monitoring. Familiarity with scripting languages such as Groovy, JavaScript, or Python for test automation. Experience with monitoring tools like AWS CloudWatch , Grafana, New Relic, Dynatrace, Datadog or AppDynamics to analyze system performance. Assist in identifying performance goals and ensuring they align with business objectives. Recommend improvements in code, system configurations, and hardware resources to enhance overall application performance.
