Job Title: Senior IBM Z Communications Programmer (ALC Specialist)

Location: Remote

Overview

We are seeking a highly specialized and experienced Senior IBM ALC programmer to support our mission-critical, ALC-based communications processing application within a z/OS environment. This role is critical for ensuring low-latency, high-volume data transfer and transactional integrity. The ideal candidate will possess deep, hands-on expertise in Assembler Language Code (ALC/BAL), applying these skills to network and messaging components.

This position requires an individual who understands the fundamental workings of the IBM z/Architecture, network stacks, and the z/OS operating system.

Key Responsibilities
  • ALC Development and Maintenance (Communications Focus): Write, debug, and maintain custom high-performance code written in Assembler Language Code (ALC/BAL) to support a communications application.
  • System Diagnosis and Debugging: Perform advanced diagnostics, including reading and analyzing system dumps (SVC, ABEND) and network traces to identify and resolve complex, intermittent communications failures at the memory and instruction level.
  • JCL and Automation: Develop and maintain complex JCL and REXX scripts for message processing automation, monitoring, and problem recovery.
Required Skills and Experience
  • 7+ years of direct, hands-on experience as an IBM Z Systems Programmer supporting high-volume transactional or communications environments.
  • Expert-level proficiency in Assembler Language Code (ALC/BAL) is mandatory, with specific experience writing system for communications protocols (TCP/IP).
  • Deep understanding of IBM z/Architecture, z/OS kernel operation, and cross-memory services.
  • Experience with advanced debugging tools (e.g., IPCS) and specialized performance monitoring utilities (e.g., OMEGAMON, NetView).
  • Strong knowledge of network protocols in the mainframe context (TCP/IP, SNA/VTAM).
  • Exceptional problem-solving skills and the ability to work independently on critical system failures.
Preferred Qualifications
  • A Bachelor's degree in Computer Science or a related technical field.
  • Current IBM Systems Programmer certification for z/OS.
  • Familiarity with mainframe security products (e.g., RACF, ACF2) as they relate to network access and channel security.
