Job Summary

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.

Key Responsibilities

• Design, develop, and maintain HLASM programs interfacing with CICS, IMS or batch processes.
• Reverse-engineer legacy assembler code for business-critical applications (e.g., payment settlement, policy adjudication).
• Optimize low-level routines for memory, speed, and IO in large transaction systems.
• Analyze and debug system and application abends using IPCS, SYSPRINT dumps, etc.
• Create and maintain system exits, user exits, and assembler-based subroutines integrated with COBOL/PLI programs.
• Collaborate with Systems Programming, DB2/IMS teams and Application Development for performance tuning.
• Ensure compliance with data privacy and security regulations (e.g., PCIDSS, HIPAA).
• Understand mainframe architectures and system-level programming concepts to work effectively with the operating system like zOS and hardware.
• Design, optimize, and manage Job Control Language (JCL) for complex batch processing, data handling, and mainframe utilities.
• Perform system-level debugging, troubleshooting, and optimization to ensure the stability and performance of Assembler-based applications and mainframe systems.
• Work closely with cross-functional teams including system analysts, application developers, and operations teams to understand requirements, translate them into technical specifications, and implement solutions.
• Create and maintain clear technical documentation including code comments, system diagrams, and user guides.
• Provide essential production support for mainframe environments which may include participating in production support rotations, diagnosing, reproducing, and resolving customer issues.
• Ensure code complies with organizational standards and best practices for security, performance, and maintainability. Adhere to security and control and change control processes.
• Provide support for batch cycles, weekend releases, and financial year-end processing.

Key Responsibilities

• 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.
