In this role, you will closely work with developers, ensuring that both functional correctness and non-functional performance metrics are continuously met and exceeded.Your expertise in automating test environments, analyzing JVM-level and system-level performance, and driving test efficiency in high-throughput mainframe ecosystems will be critical to our mission of delivering scalable, optimized, and resilient enterprise systems.Essential Skills
- Design and implement automated test frameworks for integration and system-level testing of Java and of Cobol online applications under CICS, focusing on speed, scalability, and efficiency.
- Partner with development to establish early performance baselines, define SLA/SLO thresholds, and proactively identify performance regressions.
- Automate the provisioning and configuration of performance test environments in z/OS, including Java runtimes, USS scripts, DB2 data, and WLM policies.
- Execute and analyze load, stress, and endurance tests using native and third-party tools; interpret JVM GC logs, heap dumps, CPU usage, and z/OS SMF/RMF metrics.
- Build validation harnesses for Java services utilizing JNI, JDBC, SQLJ, and DB2 for z/OS – optimized for performance-sensitive test scenarios.
- Use tools like OMEGAMON, MainView, RMF Monitor, and custom scripts to track system resource consumption, memory contention, and processor utilization (including zIIP/zAAP offload efficiency).
- Integrate validations into CI/CD pipelines and gate releases based on strict performance metrics and KPIs.
- Bachelor’s or Master’s degree in Computer Science, Engineering, or a related technical field.
