Mainframe SCM Infrastructure Engineer

Location: Buenos Aires, Argentina

Technical responsibilities — Mainframe Infrastructure Engineer (CA-Endevor + CI/CD; API/CLI + custom wrappers; REXX & Python)

• Own CA-Endevor platform administration and configuration across dev/test/prod: 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 / generate procedures to enable deterministic builds (compile/link/edit flows, copybook/include handling, and middleware hooks such as DB2/CICS/IMS where applicable).

• Build and maintain Endevor automation interfaces using supported APIs/CLI plus custom wrapper services/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/evidence, integrate with approvals, and publish results to downstream systems.

• Develop REXX utilities for z/OS-side automation (inventory queries, dataset/member validation, job/JCL generation, operational tooling, 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/monitor batch steps when required, and enforce promotion sequencing.

• Define and enforce quality gates and policy controls in pipelines: compile success, test execution where feasible, 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 + wrappers (RACF/ACF2/TSS + Endevor ACLs): least privilege, privileged access management patterns, and audit logging for API/CLI actions.

• Monitor and tune Endevor operational health and performance: 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), delivering RCA and implementing preventive fixes.

• Maintain documentation and standards: 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.
