Key Responsibilities:

Performance & Non-Functional Testing

• Design and execute performance, load, stress, capacity, scalability, endurance, spike, concurrency, and resilience testing using Apache JMeter.
• Develop realistic workload models based on production volumes, transaction profiles, peak periods, growth forecasts, and service-level requirements.
• Test REST APIs, databases, messaging interfaces, asynchronous services, batch processes, and end-to-end business workflows.
• Develop and maintain reusable JMeter performance-testing frameworks and scripts.
• Perform distributed and non-GUI JMeter execution.
• Integrate performance testing into CI/CD pipelines.
• Analyse response time, throughput, percentile latency, error rate, resource utilisation, and recovery behaviour.
• Correlate test results with application, JVM, database, infrastructure, network, and messaging metrics.
• Identify performance bottlenecks and work with development, architecture, infrastructure, operations, and database teams for resolution.
• Perform resilience testing involving component failures, dependency failures, retries, backlogs, recovery, and failover scenarios.

AI-Enabled Quality Engineering:

• Use approved AI tools for test-scenario and edge-case generation.
• Use AI assistance for JMeter/Playwright script creation, synthetic test-data preparation, log analysis, defect investigation, automation refactoring, and documentation.
• Validate all AI-generated testing assets through appropriate human review.
• Ensure confidentiality, security, traceability, and maintainability when using AI tools.
