Senior qa engineer (payments)

Are you the kind of QA engineer who enjoys digging deep into how payment systems really work — from transaction authorization to settlement — and making sure every step behaves exactly as it should?

We’re looking for a Senior QA Engineer who thrives on testing complex payment systems and transaction flows. You’ll join the Card Rails team, ensuring the reliability and quality of the infrastructure that powers card-present (POS) and card-not-present (e Commerce) payments across Africa.

This role sits at the intersection of legacy stability and modern automation, where you’ll help shape a shift-left quality strategy, build intelligent test automation, and validate payment lifecycles across acquirers, card schemes, and merchants.

If you enjoy breaking systems in smart ways, designing robust testing strategies, and ensuring mission-critical platforms run flawlessly, this role is for you.
