REMOTE Mainframe Modernization Architect – Telecom OSS

• Senior Leader with Telecom OSS infrastructure experience, including leadership of large, cross-functional modernization programs. Deep technical expertise in TIRKS circuit provisioning lifecycles.
• Strong IBM Mainframe skills (z/OS, JCL, IMS, VSAM, CICS).
• Hands-on modern architecture experience (APIs, microservices, AWS/Azure).
• Master of SQL, data modeling, and enterprise ETL migration tools.
• Proven mainframe modernization experience led or architected at least one largescale legacy modernization program using a tiered disposition model (retire, re-host, replatform, AI-assisted refactor, replace-with-COTS).
• Familiarity with real-time API enablement patterns (z/OS Connect, CICS Transaction Gateway, MQ-based request/reply) and data replication / CDC approaches (e.g., Debezium, Db2) is strongly preferred.
• Applied Gen-AI tooling for modernization hands-on experience using generative AI tools (e.g., GitHub Copilot, Amazon Q Developer / CodeWhisperer, Claude, or equivalent) for legacy code comprehension, COBOL/JCL analysis and autodocumentation, test-case generation, and AI-assisted refactoring.
• Must be able to define where AI accelerates delivery and where human-in-the-loop (HITL) review and validation are mandatory.
