"Performance Test Lead – PeopleSoft, Mainframe

Performance Test Lead - PeopleSoft Mainframe

Project Context:
We need an experienced Performance Test Lead Engineer for Enterprise General Ledger (eGL) platform which encompasses both frontend and backend components. The front-end is PeopleSoft Application and back-end is JCL COBOL running on Mainframe. The current database is DB2 (Z/OS). The eGL platform is going thourgh a change as our client needs to exit out of DB2 (ZOS) and remove PeopleSoft package dependency from DB2. The target state architecture would have PeopleSoft integration with Oracle. DB2 (Z/OS) will still exist but wont interact with PeopleSoft Application (Front-End). There will be data exchange/replication between DB2 and Oracle.

Required Experience:

• 12 years in IT and Financial Services with a strong focus on Performance Engineering and Testing.
  
• 10 years designing and implementing Performance Test Strategies for enterprise applications.
  
• Hands-on experience with LoadRunner and JMeter for frontend backend and interface performance testing.
  
• Expertise in measuring performance of data exchange and replication interfaces between heterogeneous systems (e.g. DB2 and Oracle) including:
  
• Validating data transfer latency throughput and consistency.
  
• Designing tests for ETL processes replication jobs and batch data movement.
  
• Monitoring network and middleware performance during data exchange.
  
• Strong knowledge of PeopleSoft Application performance tuning and Mainframe (JCL COBOL) batch optimization.
  
• Proficiency in SQL performance tuning for DB2 and Oracle databases.
  
• Provide recommendations for tuning system components for better throughput and response times.
  
• Leverage experience in Banking/Finance systems and General Ledger (GL) processes to ensure performance testing aligns with business-critical operations.
  

Responsibilities:

Performance Testing Strategy:

• Design and implement performance strategy for online applications and mainframe batch processes.
  
• Define performance benchmarks and SLAs in collaboration with stakeholders.
  

Execution & Analysis:

• Conduct load stress and endurance testing for online screens batch programs and data replication jobs.
  
• Simulate real-world workloads to validate system stability and responsiveness.
  
• Analyze test results to identify performance bottlenecks in application database and data exchange layers.
  
• Write and execute complex SQL queries (e.g. SELECT JOIN aggregate functions) to validate data integrity during performance tests.
  
• Help optimizing SQL queries and database interactions to improve system performance.
  
• Analyze database performance metrics and recommend tuning strategies.
  

Optimization:

• Collaborate with development and infrastructure teams to resolve performance issues and optimize application code database queries and batch job scheduling.
  

Collaboration & Reporting:

• Work with development infrastructure and DBA teams to resolve performance issues in PeopleSoft mainframe jobs and replication processes.
  
• Recommend tuning strategies for application code database queries and batch job scheduling.
  

Continuous Improvement:

• Prepare detailed performance reports highlighting application and interface performance metrics.
  
• Drive initiatives to enhance performance testing methodologies tools and automation frameworks.
  
• Stay updated on emerging trends in performance engineering and data replication technologies.
  

Preferred Skills:

• Experience with JMeter and LoadRunner or other industry leading application performance management tools.
  
• Experience with data replication tools (e.g. GoldenGate CDC solutions).
  
• Familiarity with CI/CD integration for performance testing.
  
• Strong understanding of banking/finance domain processes especially General Ledger (GL).
