OSS Solution Architect

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 cloudor 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.
