Purpose Statement

• As a level II Software Engineer in our Payments Technology team, you will play an integral part in a cross-functional team responsible for the full lifecycle of our card machine software, from concept and design, through development and testing, to deployment and ongoing operation in the field. You will design, develop, test, deploy, maintain and enhance native Android applications running on POS devices, as well as the server-side components that power them, translating requirements from the business or technical analyst and actively participating with the delivery team in design and problem-solving.

Reliability, performance and transaction integrity are non-negotiable, the code you write processes real money, in real time, at scale.
