Description and Requirements
Job Summary
MetLife is seeking a Senior Software Development Engineer to lead technical design and delivery for mission-critical mainframe applications supporting high-volume financial and payment systems. The role will focus on modernizing COBOL programs, optimizing z/OS performance, and enabling API integration through IBM z/OS Connect Enterprise Edition (EE), while ensuring reliability, security, and compliance across the PCTS, GPAY, and FMS platforms.
Key Responsibilities
• Design, develop, and optimize COBOL applications on z/OS, leveraging Enterprise COBOL 6.x features for performance and maintainability.
• Build and deploy RESTful APIs using IBM z/OS Connect EE: map copybooks/DFHCOMMAREA or CICS channels/containers to JSON; configure CICS IPIC connections; integrate with APIC/MQ.
• Author and maintain JCL, batch utilities (IDCAMS/DFSORT), and CICS transactions; ensure robust restart/recovery strategies and data integrity across DB2/VSAM.
• Implement and enforce RACF security for datasets, transactions, and API endpoints, partnering with platform/security teams on certificates and OAuth flows.
• Collaborate on workload scheduling (OPC/IBM Z Workload Scheduler) and release/change management, including lower-to-prod promotion and cutover/backout planning.
• Drive engineering best practices: code reviews, automated testing, documentation, runbooks, and operational readiness (monitoring/alerting, incident response).
• Mentor and upskill engineers; lead KT sessions and foster consistent Agile/SDLC practices across onshore/offshore teams.
Core Requirement - IBM z/OS Connect EE
• Demonstrated hands-on expertise building and operating IBM z/OS Connect EE services and APIs using IDz/z/OS Connect projects.
• Proficiency mapping mainframe data structures (copybooks/DFHCOMMAREA or CICS channels/containers) to JSON schemas and validating request/response payloads.
• Configuration experience for CICS IPIC connections, environment-specific endpoints/ports, APIC backend routing, OAuth/JWT, and certificate/keyring management.
• Troubleshooting experience across lower and production environments (e.g., BAQR* errors, authorization/JSON format issues) using logs/traces and collaboration with platform teams.
