Performance Tester Internship

Responsibilities

• You will be the expert in pushing the platform to its limits, guaranteeing optimal user experience even under peak load.
• Test Strategy &
• Design comprehensive load, stress, and endurance testing strategies for critical systems, focusing on the high-volume e-commerce checkout funnels, payment gateway integrations, and API responsiveness across the modular monolith.
• Execution & Analysis: Execute tests using industry-standard tools (e.g., JMeter, Gatling) and cloud-based load testing services.
• Analyze results to accurately identify performance bottlenecks in the Node.js/NestJS services, database queries (PostgreSQL/Redis), and infrastructure components.
• Critical Flow Testing: Specifically test the performance and throughput of key supply chain APIs and user flows, including real-time inventory checks (WMS integration), order placement (OMS), and search functionality (Meilisearch).
• Optimization Recommendations
• Collaborate closely with the SRE and development teams to translate performance data into clear, actionable optimization strategies for code, database indices, caching (Redis), and infrastructure (auto-scaling).
• CI/CD Integration: Work with the DevSecOps team to integrate performance testing as a mandatory quality gate within the CI/CD pipeline to prevent performance regressions in new deployments.
• Required Technologies & Tools
