Job description

IBM Mainframe lead (Z/OS)

Strong hands-on experience with REXX scripting, JCL, RACF security, mainframe SDLC, and z/OS automation, with nice-to-have skills in z/OS Connect EE.
Note: Current IBM Mainframe name: IBM Z

System z Series: This was a line of mainframes that evolved into the current IBM Z family. System z9 and System z10: These were specific models within the z Series family.

Key Responsibilities:

  • Develop and maintain REXX execs (scripts) to perform CRUD operations on RACF objects, including users and entitlements.
  • Review, update, and write JCL (Job Control Language) to perform batch operations involving RACF datasets.
  • Analyze and optimize existing JCL scripts and REXX execs to support RACF management automation.
  • Participate in all phases of the mainframe application development SDLC, from design and development to testing and deployment.
  • Collaborate with cross-functional teams to ensure security, compliance, and performance standards are met.
  • Document processes and maintain clear, detailed technical documentation for RACF-related automation and batch processing workflows.

Required Qualifications:

  • Proven experience with REXX scripting, especially for RACF users and entitlement automation.
  • Strong expertise in JCL, including reading, writing, and modifying batch jobs.
  • In-depth understanding of RACF (Resource Access Control Facility) and related security concepts.
  • Solid understanding of the mainframe SDLC and experience with enterprise-level development and deployment practices.
  • Ability to troubleshoot and optimize mainframe processes independently.
  • Intangibles: Sense of Urgency, Proactiveness, Professionalism - Excellent verbal and written communication skills.

Nice To Have

  • Hands-on experience in z/OS Connect EE (Enterprise Edition), including configuration, integration and setup.

Terms:

  • JCL (Job Control Language): is a scripting language used on IBM mainframe operating systems (like z/OS) to instruct the system how to execute jobs. It essentially tells the system what programs to run, what data to use, and what resources are needed for a job. JCL is a crucial part of mainframe operations, enabling batch processing, scheduling, and resource
  • REXX (Restructured Extended Executor): is a high-level, general-purpose scripting/programming language developed by IBM.
  • CRUD operations (Create, Read, Update, Delete): it refers to the four fundamental operations used to manage data in databases and applications. These operations are essential for interacting with databases and building data-driven applications.
  • RACF (Resource Access Control Facility): a software security product by IBM that provides access control and auditing for z/OS and z/VM operating systems. It's designed to manage user authentication, resource access, and logging for mainframe environments. Essentially, RACF helps organizations secure their mainframe environment by controlling who can access specific resources and what actions they can perform
  • z/OS Connect EE: a product that extends z/OS Connect, enabling you to expose and access z/OS assets (like CICS, IMS, Db2, and MQ) as RESTful APIs using JSON, says IBM. It allows for rapid development and deployment of APIs, simplifying integration with cloud and mobile applications, and leveraging the security and scalability of the z/OS platform
