Performance Tester

Role and responsibility: - Identifies performance test environment requirements and works with the infrastructure, network operations, environment and release teams to setup the environment for effective SLA measurements - Works with the different project stakeholders to help define and document performance SLAs, requirements and expectations around critical factors such as response time, throughput, transactions/second, concurrent users, CPU utilization, memory, disk, network utilization, thread counts, connection pooling, hit ratios - Learns the underlying architecture under the COTS products and Enterprise applications utilizing the blueprints and architectural diagrams available within the program - Develops data driven test scripts and executes performance and load testing of the applications - Designs and executes daily load tests large system level performance tests - Collects, analyzes and reports performance testing results to the project, program and business stakeholders - Reviews the performance test scripts created or modified by peers to ensure compliances with standards - Collaborates with the test automation team to leverage reusability of existing scripts - Creates knowledge management related deliverables such as tools related processes and procedures - Be the performance test specialist Initial Analysis and Presenting Strategy - Capture business goals, critical workflows, and expectations. - Align stakeholders on performance testing scope, goals, and deliverables. Requirements and Planning documents - Define performance metrics (like throughput, latency, error rates) Identify: - Business-critical paths - Peak transaction rates - Processes for high business impact Environment Setup : Ensure the test environment mimics production like in terms of Hardware, Software & Configuration Script Development : Using JMeter, Record key business processes, Parameterize for real-world data, Correlate to handle session data and tokens Workload Simulation : Integrate JMeter with Azure Load Testing to Distribute load across regions, Simulate user behavior at scale & Execute stress, steady load, and spike tests Monitoring and Analysis - Real-time monitoring of: Resource consumption, Latency & Error rates - Collect metrics: Avg/max response times, Throughput & Resource utilization - Diagnose issues: Database locks, Memory leaks & Inefficient code paths Optimization (support developer) - collaborate with dev teams to Fix performance bottlenecks, Re-run load tests after fixes & Validate improvements Reporting - Create detailed reports covering: Scenarios, Test environment, Load profiles & outcome - Present findings to stakeholders with focus on: System strengths & Areas requiring improvement Qualifications - Min 7 years Performance testing experience - Requires Mobile App testing knowledge for both Hybrid and Native Apps - Should have a basic knowledge on Six Sigma Methodology and statistics - Experience in test automation and proficiency in creating automated unit, build and regression test suites - Should have knowledge on analyzing the performance of mobile App - Trouble shooting performance related technical issues and strategizing performance tests for large or distributed programs Skills: Performance Tuning, Jmeter, Api Testing, Load Testing, Scripting, Sql Queries Experience: 7.00-10.00 Years
