Telecom OSS Modernization Architect â?? TIRKS/SOAC/LFACS Migration Specialist

Job Summary

We are seeking a Telecom OSS Modernization Architect with deep expertise in legacy Telcordia/Ericsson OSS systems (TIRKS, SOAC, LFACS) and modern cloud/microservices architecture. This role will lead the end-to-end transformation of legacy mainframe-based circuit provisioning systems into modern, service-based platforms — covering architecture design, AS-IS to TO-BE mapping, data migration, integration rationalization, and cutover planning.

Required Skills

• Telecom OSS Expertise: 10–15+ years of telecom infrastructure experience, with deep technical knowledge of the Ericsson/Telcordia suite, specifically circuit provisioning lifecycles within TIRKS.
• Legacy Mainframe Proficiency: Comprehensive background in IBM mainframe environments, including z/OS internals, JCL, IMS databases, VSAM, and CICS transaction processing.
• Modern Systems Architecture: Practical experience with API-first architectures, Microservices, Site Reliability Engineering (SRE) principles, and cloud environments like AWS or Azure.
• Data & ETL Skills: Mastery of advanced SQL, data modeling, database design principles, and enterprise data migration tooling.

Education

Bachelor's or Master's degree in Telecommunications, Computer Science, or Network Engineering.

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.
• As-Is to To-Be Mapping: Map current-state (AS-IS) legacy TIRKS data flows, circuit provisioning rules, and system interfaces to design future-state (TO-BE) software architectures.
• Data Migration & Validation: Oversee the structural extraction, cleanup, and loading (ETL) of critical network inventory, connecting facility assignments (CFAs), and trunk line data into new systems.
• Integration Rationalization: Deconstruct and rewire complex interfaces linking TIRKS to other Telcordia modules like SWITCH, FACS, WFA, and SOAC.
• Risk & Cutover Management: Formulate phased migration and system decomposition strategies to guarantee zero disruption to ongoing network order controls or field dispatch workflows.
