Summary: The Telecom OSS Modernization Architect – Legacy Mainframe to Cloud-Native Specialist is responsible for transitioning legacy IBM mainframe systems to modern cloud-native architectures. This role involves decomposing monolithic systems, designing API-first solutions, and leading migrations to cloud environments. The architect will implement high-performance APIs and modernize data processes during the transition. A strong background in cloud technologies and microservices is essential for success in this position.

Key Responsibilities:

  • Define end-to-end functional architecture for transitioning legacy mainframe systems into modern platforms.
  • Decompose legacy mainframe business logic and databases into modern, decoupled microservices.
  • Architect and implement high-performance APIs to expose key functionalities.
  • Translate legacy concepts into modern domain models using Domain-Driven Design principles.
  • Lead the containerization and migration of core functionality into cloud environments.
  • Replace legacy batch processes with real-time, event-driven pipelines.
  • Implement data-sync strategies to run legacy and new cloud services in parallel during transition phases.

Key Skills:

  • Legacy Decoupling: Proven track record of decomposing IBM mainframe systems (z/OS, IMS DB/DC, DB2) using patterns like the Strangler Fig pattern.
  • Cloud & Containerization: Expert-level mastery of Kubernetes, Docker, and enterprise cloud architecture patterns.
  • API & Service Mesh: Extensive experience with API gateways, service mesh (Istio/Linkerd), and schema protocols (OpenAPI/Swagger).
  • Modern Development: Proficiency in Java (Spring Boot), Go, or Python for building highly resilient, distributed microservices.
  • Data Pipelines: Experience with real-time data streaming (Kafka, Flink) and modern distributed databases (PostgreSQL, MongoDB).
  • Education: Bachelor’s or Master’s degree in Telecommunications, Computer Science, or Network Engineering.
