Senior Performance Engineer

Working within the Technology QA (Tech QA) team, the Senior Performance Engineer (SPE) is responsible for ensuring the performance, availability, scalability and reliability of a suite of products. Collaborating with multiple stakeholders to develop a fit for purpose performance engineering and testing strategy that covers all aspects of the product, including cross program dependencies.

Job Outline:

• Participate in all phases of the Performance Engineering lifecycle Requirement Gathering, Design, Development, Scripting, Execution, Analysis, Troubleshooting, Tuning, Reporting


• Collaborate with Architecture, Solution Design and Development teams to design for Performance.


• Understand Non-Functional Requirements and the application, including the underlying architecture and technology stack, and ensure the system performance is within defined SLAs


• Execute appropriate performance tests against the established Performance Testing Framework for Component Tests and End to End Tests across systems and understand the Cross Program Dependencies and ensure performance tests are carried out with understanding of impact.


• Ensures each feature/design requirement has an appropriate non-functional test which exercises the architecture and design and demonstrates appropriately the stability of the solution and conduct thorough analysis of test results at feature level identifying bottlenecks and issues, working with Site Reliability Engineers to take appropriate diagnostic action.


• Define test data strategy and collaborate with the Test Data Management team to generate on-demand data and collaborate with the Architect for defining the Workload model. Monitor production workloads and performance, and update/refine the workload model


• Collaborate with Architects and Product Owners to establish APM, monitoring and tracing strategy. Leverage Application performance management and profiling tools to identify, isolate and resolve performance bottlenecks
