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
