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

- OwnCA-Endevor platform administration and configurationacross dev/test/prod: tasks/STCs, repository connectivity, libraries, SMP/E maintenance, upgrades, and currency management.
- Engineer and govern theEndevor inventory model(environments/systems/subsystems/types/stages/mappings) aligned to SDLC, release governance, and separation of duties.
- Configure and maintainprocessors / generate proceduresto enable deterministic builds (compile/link/edit flows, copybook/include handling, and middleware hooks such as DB2/CICS/IMS where applicable).
- Build and maintainEndevor automation interfacesusing supportedAPIs/CLIpluscustom wrapper services/scripts, including versioning, backward compatibility, error contracts, and usage standards.
- DevelopPython automation and wrapper toolingto orchestrate Endevor lifecycle actions (create/update packages, move/generate/promote), capture metadata/evidence, integrate with approvals, and publish results to downstream systems.
- DevelopREXX utilitiesfor z/OS-side automation (inventory queries, dataset/member validation, job/JCL generation, operational tooling, exception reporting), integrating with wrapper interfaces where needed.
- Implement and supportJenkins pipelines (pipeline-as-code)that invoke Endevor viaAPI/CLI wrappers, manage credentials securely, submit/monitor batch steps when required,



and enforce promotion sequencing.
- Define and enforcequality gates and policy controlsin pipelines: compile success, test execution where feasible, static analysis, dependency checks, and required approvals before promote.
- Implementtraceability and provenanceend-to-end: map commit/build IDs to Endevor element/package identifiers, capture promotion history, label builds/releases, and support audit evidence retrieval.
- Administersecurity controlsacross Endevor + wrappers (RACF/ACF2/TSS + Endevor ACLs): least privilege, privileged access management patterns, and audit logging for API/CLI actions.
- Monitor and tuneEndevor 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), deliveringRCAand implementing preventive fixes.
- Maintaindocumentation and standards: API/CLI wrapper contracts, REXX/Python code standards, pipeline templates, runbooks, DR procedures, and onboarding guidance for application teams.
- Define, test, and executebackup/restore and DRprocedures for Endevor repositories, critical datasets, and wrapper components, including routine DR exercises and validation evidence.
