This role goes beyond conventional Java development — we need someone who understands how to engineer high-performance, low-latency Java applications that run natively on the z/OS platform and integrate seamlessly with legacy enterprise systems.This position requires deep knowledge of Java in the context of z/OS internals, particularly in the areas of Java Native Interface (JNI), database interaction (JDBC, SQLJ), and system-level online performance. You will work with both legacy and modern components to develop robust, high-throughput services that are critical to enterprise operations.Essential Skills
- Develop and optimize Java-based applications running natively on IBM z/OS in online mode under CICS
- Analyze and improve performance at the JVM level, focusing on memory usage, tuning, and CPU cycles on z/OS.
- Integrate Java applications with native z/OS components using JNI, C/C++, and LE (Language Environment) interfaces.
- Implement efficient data access solutions using JDBC, SQLJ, and DB2 for z/OS best practices.
- Collaborate closely with z/OS systems programmers, DBAs, and COBOL/CICS developers to ensure reliable and performant interoperability.
- Review SMF records, RMF reports, and monitor WLM metrics to guide tuning and system integration.
- Develop and maintain shell scripts, and support automation for Java workloads on z/OS.
- Drive initiatives to modernize legacy systems using Java and hybrid integration models.
