Role: Performance Test Engineer (2+ Years Experience) Location: Coimbatore (In Office) Job Summary: We are seeking a skilled Performance Test Engineer with hands-on experience in testing both serverless and traditional server-based systems , as well as mobile applications . The ideal candidate will have a strong understanding of performance testing tools, cloud platforms (AWS/Azure/GCP), CI/CD pipelines, and mobile environments. You will be responsible for identifying bottlenecks, simulating load, and ensuring the scalability, reliability, and efficiency of applications under varying loads and network conditions. Key Responsibilities: Design, develop, and execute performance, load, and stress tests for applications built on serverless (e.g., AWS Lambda) and server-based (e.g., Node.js, Java) architectures. Plan and conduct mobile performance testing across different devices and network conditions to simulate real-world usage. Collaborate with development, DevOps, and mobile teams to define test scenarios based on real-world workloads , SLAs , and user behaviour patterns . Analyses test results to identify system bottlenecks, CPU/memory utilization issues, and latency problems across both web and mobile platforms . Monitor and benchmark API performance, infrastructure scalability, third-party system integrations, and mobile responsiveness. Use cloud-native tools and third-party solutions (e.g., AWS X-Ray, CloudWatch, k6 , JMeter , Gatling , Artillery ) to simulate and monitor traffic. Automate performance tests and integrate them into CI/CD pipelines . Generate detailed test reports with actionable insights and optimization recommendations for both web and mobile systems. Continuously refine performance testing strategies for scalability, cost-efficiency , mobile performance , and test coverage . Required Skills & Experience: 2+ years of hands-on experience in performance and load testing . Practical experience with tools such as k6 , Apache JMeter , Artillery , Gatling , or similar. Solid understanding of server less services (AWS Lambda, Step Functions, API Gateway) and server-based systems (e.g., EC2, containerized APIs). Experience monitoring performance using tools like CloudWatch , X-Ray , or equivalent. Familiarity with distributed tracing tools such as Open Telemetry , Jaeger , or AWS X-Ray . Proficiency in JavaScript/Node.js, Java , or Python for scripting and automation. Familiarity with CI/CD pipelines (e.g., GitHub Actions, GitLab CI, Jenkins) and experience embedding performance tests into workflows. Experience with mobile performance testing using tools like Charles Proxy , Firebase Performance Monitoring , Xcode Instruments , or Android Profiler . Knowledge of API protocols (REST, WebSocket’s), authentication mechanisms, and latency-related factors. Experience in cloud environments, preferably AWS . Strong understanding of auto-scaling mechanisms in both server less and traditional environments. Nice to Have: Proficiency with IaC tools like Terraform, AWS CloudFormation, or Serverless Framework. Knowledge of event-driven architectures and message queues like Amazon SQS, Kafka, or RabbitMQ. Awareness of security and compliance considerations in performance testing (e.g., rate limiting, HIPAA, GDPR). Basic understanding of front-end performance testing using Lighthouse, Webpage Test, or Sitespeed.io. Experience with Real User Monitoring (RUM) tools like New Relic Browser, Datadog RUM, or Google Analytics. Mobile performance testing exposure across platforms (iOS/Android) and networks (3G/4G/5G) including battery usage, cold start time, and memory profiling. Test data generation using Mockaroo, Faker.js, or custom scripts.
