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.
