Performance Test Engineer

To execute end-to-end Performance Testing for SAP S/4HANA and its integrated systems, ensuring reliability, scalability, and stability of enterprise applications across UI, API, and backend layers.

The Performance Test Engineer will work closely with the Test Lead, Basis, and Infrastructure teams to design test scripts, execute workloads, analyze results, and provide actionable insights for performance optimization.

Key Responsibilities

Performance Test Design & Planning

• Participate in requirement analysis for SAP S/4HANA applications and all integrated boundary systems, including middleware, APIs, IDocs, batch jobs, and Kafka event flows, to understand business-critical scenarios and Non-Functional Requirements (NFRs).

• Translate SAP and integration NFRs into measurable KPIs such as dialog response time, API latency, IDoc processing time, batch job runtime, queue throughput, event lag, and system resource utilization across SAP application, HANA DB, middleware, and GCP infrastructure.

• Assist in defining workload models and concurrency patterns based on SAP Day-in-the-Life operationscovering UI (SAP GUI/Fiori), API/OData requests, IDoc triggers, background jobs, file interfaces, and Kafka message burstsensuring realistic simulation of end-to-end business processes.

• Support preparation of the Performance Test Plan covering SAP modules (MM, SD, WM, FI), non-SAP boundary applications, integration flows, batch job schedules, and event-driven workloadswith aligned timelines, entry/exit criteria, and environment dependencies for each release.

Scripting & Test Data Preparation

• Develop and maintain performance test scripts using LoadRunner (SAP GUI, SAP Web, Web HTTP) and Apache JMeter ( APIs, Kafka).
• Implement correlation and parameterization techniques to ensure realistic and reusable scripts.
• Configure SAP GUI scripting for SAP business flows such as Goods Receipt, Goods Issue, ASN Processing, and Stock Movements.
• Create, manage, and parameterize test data sets (materials, batches, storage bins, delivery numbers, vendor IDs, customer IDs, IDoc payloads, Kafka event messages) ensuring data integrity across repeated test cycles.
• Maintain structured version control and documentation for all scripts, test data files, correlation rules, execution settings, and environment-specific configurations using Git, Confluence, or repository standards.

Test Environment Setup & Validation

• Validate test environment readiness with the support of Basis and Infra teams.
• Verify SAP system configurations (work processes, logon groups) and ensure GCP resources are appropriately allocated.
• Coordinate with environment teams to confirm connectivity, user access, and interface availability before execution.
• Support test data refresh and environment cleanup activities.

Test Execution & Monitoring

• Execute different types of performance tests Load, Stress, Endurance, and Failover tests across SAP and non-SAP systems.
• Monitor system performance during test runs using tools such as Dynatrace, Grafana, SAP ST03/ST12/STAD.
• Track and log transaction throughput, response time, and error rates during execution.
• Capture system resource utilization across application, database, and middleware layers.
• Ensure proper logging, evidence capture, and adherence to test governance during execution.

Analysis & Reporting

• Analyze test results to identify bottlenecks in application, API, database, and network layers.
• Correlate findings with Dynatrace traces, SAP Workload Analysis, and HANA DB performance statistics.
• Prepare performance summary reports including observations, root cause hypotheses, and improvement recommendations.
• Highlight deviations from SLAs and work with the Test Lead and development teams to retest after fixes.
• Maintain an issue tracker for performance defects and assist in validation of post-tuning test runs.

Collaboration & Continuous Improvement

• Work closely with the Performance Test Lead, SAP Basis, Integration, and Infrastructure teams to troubleshoot bottlenecks.
• Participate in regular performance review meetings and provide technical updates on execution progress.
• Support test automation and CI/CD integration of performance tests (using Jenkins or equivalent).
• Contribute to the maintenance of reusable test assets, data sets, and performance reports in the project repository.
• Continuously upskill on new tools, SAP modules, and GCP performance monitoring features.

Experience & Qualifications

• 47 years of experience in Performance Testing and Analysis, with 2+ years in SAP S/4HANA environment.
• Hands-on experience scripting and executing with LoadRunner and JMeter.
• Good understanding of SAP business transactions (MM, SD, WM, FI) and HANA database behavior.
• Working knowledge of monitoring and troubleshooting via Dynatrace, Grafana, and SAP ST03/STAD.
• Exposure to API performance testing (OData, REST, Kafka).
• Strong analytical skills and ability to interpret logs and performance metrics.
• Bachelors degree in Computer Science, Information Systems, or equivalent.

Success Metrics

• On-time execution of performance test cycles and readiness reports.
• Accuracy and quality of performance defect identification.
• SLA adherence for critical business scenarios.
• Reusability of test scripts and assets across sprints.
• Contribution to performance improvement and tuning initiatives.
• Collaboration effectiveness and adherence to test governance standards.
