Job Description
We're seeking a highly skilled Senior Assembler Programmer with deep expertise in HLASM development in zOS environments. This role supports low-level system programming and performance-sensitive banking and insurance applications such as transaction authorization, batch reconciliation, and legacy claim processing. The role involves designing, developing, and maintaining HLASM programs, reverse-engineering legacy code, optimizing routines, debugging system abends, and creating system exits. It also requires collaboration with various teams, ensuring compliance, and managing JCL for complex batch processing.
Good To Have:
- Experience with COBOL or other mainframe languages
- Strong working knowledge of IBM MQSeries for messaging and integration
- Familiarity with mainframe automation tools or ITIL processes
- Exposure to modernization projects (e.g., reengineering or replatforming mainframe workloads)
- Understanding of Agile methodologies and DevOps for mainframe (e.g., Endevor, Git, Jenkins for zOS)
- Knowledge of IBM zOS internals, storage and file systems (VSAM, zFS, etc.)
- Experience in Problem diagnosis, dump reading and debugging with IPCS a plus
- Knowledge of REXX
Must Have:
- Design, develop, and maintain HLASM programs interfacing with CICS, IMS or batch processes.
- Reverse-engineer legacy assembler code for business-critical applications.
- Optimize low-level routines for memory, speed, and IO in large transaction systems.
- Analyze and debug system and application abends using IPCS, SYSPRINT dumps.
- Create and maintain system exits, user exits, and assembler-based subroutines.
- Integrate assembler-based subroutines with COBOL/PLI programs.
- Collaborate with Systems Programming, DB2/IMS teams and Application Development.
- Ensure compliance with data privacy and security regulations.
- Understand mainframe architectures and system-level programming concepts.
- Design, optimize, and manage Job Control Language (JCL).
- Perform system-level debugging, troubleshooting, and optimization.
- Work closely with cross-functional teams.
- Create and maintain clear technical documentation.
- Provide essential production support for mainframe environments.
- Ensure code complies with organizational standards and best practices.
- Adhere to security and control and change control processes.
- Provide support for batch cycles, weekend releases, and financial year-end processing.
