We are currently delivering a major Billing Transformation Programme, introducing a new enterprise billing platform to replace our existing system. Alongside this transformation, we must continue to support and maintain our current platform, ensuring continuity and accuracy while carefully managing complex and business‑critical data, processes, and structures. This creates a unique opportunity to be part of a high‑impact programme, helping to protect and evolve our billing capability while transitioning to a modern, future‑ready solution.

This role is both strategic and hands‑on, requiring you to define QA frameworks while actively participating in testing activities to support successful delivery. This position is ideal for a QA professional who thrives in transformation programmes, enjoys working across complex system, data, and business validation scenarios, and can lead quality initiatives while stepping into execution when needed.
