Software Engineer in Test – Performance Testing

Responsibilities

• Design, develop, and execute scalable performance test strategies to validate the reliability, scalability, and responsiveness of enterprise applications and distributed systems.
• Develop and maintain automated performance test scripts using k6 to simulate real-world user workloads and identify system bottlenecks.
• Analyze application, database, and infrastructure performance metrics to identify performance issues and provide recommendations for optimization.
• Design and maintain reusable performance testing frameworks, utilities, dashboards, and reporting solutions.
• Build and maintain performance dashboards and automated reports using InfluxDB, Grafana, and Flux queries.
• Collaborate with Software Engineers, Product Managers, DevOps, and Infrastructure teams to establish performance requirements and integrate performance testing into the software development lifecycle.
• Integrate performance testing into Azure DevOps CI/CD pipelines to enable continuous performance validation.
• Execute load, stress, endurance, spike, scalability, and capacity testing across cloud-native and distributed application environments.
• Develop SQL queries to support test validation, performance analysis, and database performance investigations.
• Produce performance analysis reports, communicate findings, and partner with development teams to validate performance improvements.
• Support performance testing in containerized and distributed environments using Docker and Kubernetes where applicable.
• Promote performance engineering best practices, standards, and continuous improvement initiatives.
• Define, monitor, and analyze key performance metrics, including latency, throughput, and system resource utilization, using observability platforms such as InfluxDB, Prometheus, Grafana, and similar tools.
