Group Technical Architect

Dallas, Texas Job Summary Telecom OSS Modernization Architect (TIRKS Migration) Job Summary Lead the architectural transformation of legacy, monolithic TIRKS mainframe systems into modern cloud and midrange platforms. You will map AS-IS data flows, deconstruct Telcordia interfaces, and oversee data migration to ensure zero disruption to network order controls. This is a hands-on architect role that pairs deep mainframe knowledge with a modern, AIassisted modernization approach — using Gen-AI tooling to accelerate legacy code comprehension, artifact generation, and migration — while safeguarding the reliability and integrity of mission-critical OSS provisioning. 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. Preferred / Nice to Have Prior experience modernizing Telcordia OSS estates. Exposure to TM Forum standards (SID, eTOM, Open APIs) for target-state architecture. Experience building an AI-assisted modernization narrative or accelerator framework for enterprise migration programs. Familiarity with legacy data formats and constructs (EBCDIC, COMP-3, copybooks) and modern data pipelines.
