Job description

Key Requirements

• Senior Leader with 15+ years of 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.
• Degree in Computer Science, Telecom, or Network Engineering.

Top Responsibilities

1. System Transformation — Map and migrate legacy TIRKS mainframe systems to cloud or service‑based platforms.
2. Interface Deconstruction — Rewire complex integrations between TIRKS and adjacent modules such as SWITCH, FACS, WFA, and SOAC.
3. Data Migration — Oversee extraction and validation of critical network inventory, CFAs, and trunk line data.
4. AI‑Assisted Modernization — Establish and govern the use of Gen‑AI tooling across the modernization lifecycle: reverse‑engineering undocumented logic, generating design and test artifacts, and accelerating code refactoring — with appropriate guardrails, review gates, and quality controls.
