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.
