Overview

J.P. Morgan is seeking a Mainframe SCM Infrastructure Engineer to own and evolve the CA-Endevor platform and associated CI/CD toolchain. This role sits within the Corporate Sector and is based in Buenos Aires, Argentina.

Technical Responsibilities

• •Own CA-Endevor platform administration and configuration across dev/test/prod environments, including tasks/STCs, repository connectivity, libraries, SMP/E maintenance, upgrades, and currency management.
• •Engineer and govern the Endevor inventory model (environments, systems, subsystems, types, stages, mappings) aligned to SDLC, release governance, and separation of duties.
• •Configure and maintain processors and generate procedures to enable deterministic builds, including compile/link/edit flows, copybook/include handling, and middleware hooks such as DB2, CICS, and IMS where applicable.
• •Build and maintain Endevor automation interfaces using supported APIs/CLI plus custom wrapper services and scripts, including versioning, backward compatibility, error contracts, and usage standards.
• •Develop Python automation and wrapper tooling to orchestrate Endevor lifecycle actions (create/update packages, move/generate/promote), capture metadata and evidence, integrate with approvals, and publish results to downstream systems.
• •Develop REXX utilities for z/OS-side automation including inventory queries, dataset/member validation, job/JCL generation, operational tooling, and exception reporting, integrating with wrapper interfaces where needed.
• •Implement and support Jenkins pipelines (pipeline-as-code) that invoke Endevor via API/CLI wrappers, manage credentials securely, submit and monitor batch steps when required, and enforce promotion sequencing.
• •Define and enforce quality gates and policy controls in pipelines: compile success, test execution, static analysis, dependency checks, and required approvals before promote.
• •Implement traceability and provenance end-to-end: map commit/build IDs to Endevor element/package identifiers, capture promotion history, label builds/releases, and support audit evidence retrieval.
• •Administer security controls across Endevor and wrappers using RACF/ACF2/TSS and Endevor ACLs, applying least privilege, privileged access management patterns, and audit logging for API/CLI actions.
• •Monitor and tune Endevor operational health and performance including task health, API/CLI throughput, contention/ENQs, backlog/queue behavior, repository growth, and recovery procedures.
• •Troubleshoot complex failures across the toolchain (processor failures, package conflicts, wrapper/API errors, Jenkins pipeline breaks, inventory drift) and deliver root cause analysis with preventive fixes.
• •Maintain documentation and standards covering API/CLI wrapper contracts, REXX/Python code standards, pipeline templates, runbooks, DR procedures, and onboarding guidance for application teams.
• •Define, test, and execute backup/restore and DR procedures for Endevor repositories, critical datasets, and wrapper components, including routine DR exercises and validation evidence.
