responsibilities - Mainframe Infrastructure Engineer (CA-Endevor + CI/CD; API/CLI + custom wrappers; REXX & Python)\nOwn CA-Endevor platform administration and configuration across dev/test/prod: tasks/STCs, repository connectivity, libraries, SMP/E maintenance, upgrades, and currency management.\n\nEngineer and govern the Endevor inventory model (environments/systems/subsystems/types/stages/mappings) aligned to SDLC, release governance, and separation of duties.\n\nConfigure 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).\n\nBuild and maintain Endevor automation interfaces using supported APIs/CLI plus custom wrapper services/scripts, including versioning, backward compatibility, error contracts, and usage standards.\n\nDevelop 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.\n\nDevelop 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.\n\nImplement 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.\n\nDefine and enforce quality gates and policy controls in pipelines: compile success, test execution where feasible, static analysis, dependency checks, and required approvals before promote.\n\nImplement 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.\n\nAdminister security controls across Endevor + wrappers (RACF/ACF2/TSS + Endevor ACLs): least privilege, privileged access management patterns, and audit logging for API/CLI actions.\n\nMonitor and tune Endevor operational health and performance: task health, API/CLI throughput, contention/ENQs, backlog/queue behavior, repository growth, and recovery procedures.\n\nTroubleshoot complex failures across the toolchain (processor failures, package conflicts, wrapper/API errors, Jenkins pipeline breaks, inventory drift), delivering RCA and implementing preventive fixes.\n\nMaintain documentation and standards: API/CLI wrapper contracts, REXX/Python code standards, pipeline templates, runbooks, DR procedures, and onboarding guidance for application teams.\n\nDefine, test, and execute backup/restore and DR procedures for Endevor repositories, critical datasets, and wrapper components, including routine DR exercises and validation evidence.","description_format":"text","description_chars":2852,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Supply
