Position Overview

QT Global Software Ltd is currently in the process of revamping the Rwanda Revenue Authority (RRA)’s Domestic Tax Systems. These systems include the Electronic Invoicing System known as EBM, e-Tax, and the Local Government and Revenue Accounting and Reporting systems. In that regard, QT Global Software Ltd is looking for a Senior Tax Expert to support the process of revamping these tax systems.

The Senior Tax Expert (Tax Systems Business Analyst) plays a dual strategic role, combining deep tax domain knowledge with business analysis capabilities to drive the successful development and deployment of desired tax system functionalities. This role includes solution shaping, requirements management, system validation, and governance support across the tax systems revamp process.

The incumbent acts as the critical bridge between tax subject-matter expertise and technology delivery — ensuring that tax systems are designed, built, and deployed in full alignment with tax laws, business objectives, and operational needs.

Ensure proper defect management, resolution tracking, and regression testing for tax rule changes

Own tax quality assurance from a domain perspective throughout system delivery
