- Support proof-of-concepts, mock migrations, and dry runs by validating mappings, reconciling results, and refining migration design.

- Produce detailed migration documentation, including design specifications, validation rules, reconciliation reports, and planning artifacts.

- Apply industry best practices for migration planning, including :

1. End-to-end traceability from source to target.

validation, and reconciliation.

- Experience with Amdocs (Ensemble, C1), Netcracker, and Siebel CRM systems.

- Knowledge of TM Forum SID models and their application in telecom data standardization.

- Proven experience in subscriber & billing data migrations (discovery to cutover).

- Familiarity with data governance, audit, and compliance frameworks in telecom

environments.

Preferred Qualifications :

- Exposure to migration accelerators, ETL tools like Informatica, or data validation frameworks.

- Experience working in Agile environments with cross-functional teams.
