Job Title: Telecom OSS Modernization Architect – TIRKS/SOAC/LFACS Migration Specialist 

Required Skills: 

• Telecom OSS Expertise: At least 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.
