Performance Tester & Load Testing

Key Responsibilities

• Design, develop, and execute performance and load-testing scenarios across HTTP/API endpoints and event-driven/WebSocket traffic.
• Build and execute load, stress, spike, endurance, and scalability tests.
• Analyze performance metrics, including response times, latency percentiles (P50, P90, P95, P99), error rates, and throughput.
• Identify performance bottlenecks across application, API, database, and infrastructure layers.
• Develop realistic test scenarios that simulate production-like user behavior and traffic patterns.
• Configure and execute distributed load tests to evaluate application performance under high-volume traffic.
• Monitor application performance and system health during test execution.
• Use observability tools to analyze logs, metrics, traces, and resource utilization.
• Collaborate with developers, architects, and infrastructure teams to troubleshoot performance issues and recommend optimizations.
• Prepare detailed performance test reports, findings, and recommendations.
• Support performance tuning, root cause analysis, and remediation activities.

Required Technical Skills

• 10+ years of experience in Quality Engineering / Software Testing.
• Strong hands-on experience in Performance Testing and Load Testing.
• Experience with performance testing tools such as:
• Locust
• Gatling
• JMeter or similar performance testing frameworks.
• Strong understanding of HTTP protocols, REST APIs, and WebSocket communication.
• Experience designing and executing performance test scenarios for distributed systems.
• Knowledge of load generation, concurrency, throughput, latency, and response-time analysis.
• Experience analyzing performance metrics, including P95/P99 latency and error rates.
• Strong troubleshooting and bottleneck identification skills.
• Familiarity with observability and monitoring tools such as:
