This position requires deep, demonstrated Java expertise. Knowledge of COBOL and prior experience converting mainframe systems to modern systems is a significant differentiator, given that the task order translates the legacy code base to a modern software language (i.e., Java) within a micro services architecture. *This position is contingent upon contract award.* Responsibilities: Translate and re-factor the legacy code base into a modern software language (i.e., Java) within the defined micro services architecture. Update and perform static code analysis of the current legacy code base — including COBOL, ASM, JCLs, and Copybooks — to identify functional and non-functional code across the entire baseline. Leverage AI/ML tools and processes to translate the legacy code base where appropriate, ensuring those tools and processes are used efficiently and effectively. Optimize translated code leveraging microservices architecture or other architecture that modularizes functionality. Design and develop new software products or major enhancements to existing software; address problems of systems integration, compatibility, and multiple platforms. Implement translated code so it functions within the pre-production environment supporting development, test, and integration activities.
