Analyse response times, throughput, error rates, resource utilisation and overall application behaviour under varying workloads.
Identify performance bottlenecks and conduct root cause analysis across application, database, infrastructure and integration layers.
Work collaboratively with engineering, infrastructure and application teams to investigate performance issues and implement improvements.
Support performance tuning activities and coordinate subsequent testing to validate improvements.
Establish performance baselines, acceptance criteria, service-level targets and measurable non-functional requirements.
Produce detailed performance test results, dashboards and reports, communicating findings to technical and programme stakeholders.
Manage defects identified through performance testing, ensuring appropriate investigation, remediation and re-testing.
Support test environment preparation, test data requirements and overall performance test execution readiness.
Significant commercial experience in non-functional testing and performance engineering within complex enterprise environments.
Strong, hands-on experience with Apache JMeter, including script development, parameterisation, correlation, test execution and results analysis.

Strong understanding of core banking transaction flows and the performance requirements associated with high-volume banking platforms.
Proven experience delivering load, stress, endurance, volume and scalability testing.
Ability to develop realistic performance scenarios and translate business requirements and transaction volumes into measurable technical performance criteria.
Strong analytical skills, with the ability to identify and distinguish application, database, infrastructure and integration-related performance bottlenecks.
Experience conducting performance investigations, defect analysis and root cause identification.
Experience working across complex, integrated technology environments.
Strong communication skills, with the ability to present technical findings and recommendations to engineering and programme stakeholders.
