Job Title: Telecom OSS Modernization Architect Legacy Mainframe to Cloud-Native Specialist
Required Skills:

Core Responsibilities:
Architecture Transformation: Define end-to-end functional architecture to transition legacy, monolithic TIRKS mainframe systems (z/OS, IMS, DB2) into modern midrange, cloud, or service-based platforms.
Monolith Decomposition: Deconstruct legacy TIRKS PL/I or COBOL business logic, IMS databases, and JCL paths into modern, decoupled microservices.
API-First Design: Architect and enforce the implementation of high-performance RESTful or gRPC APIs to expose circuit design, inventory, and provisioning capabilities.
Domain-Driven Design (DDD): Translate historical TIRKS concepts like Connecting Facility Assignments (CFAs), circuit IDs, and trunk layouts into modern domain models.
Cloud-Native Migration: Direct the containerization (Kubernetes) and migration of core functionality into cloud environments (AWS, Azure, or GCP).
Event-Driven Integration: Replace legacy batch jobs and CICS transactions with real-time, event-driven pipelines using Apache Kafka.
Dual-Run Strategy: Implement data-sync strategies (like Change Data Capture) to run TIRKS and new cloud services in parallel during transition phases.
